SUPPLEMENTARY REPORT ON THE LOW-INCOME POPULATION: 1966 TO 1972
This report presents detailed social and e.7.o-nomic statistics for the population of the LIn..tedStates below the low-income level' in 196e, rn1972, based on the March 1967 to 1973 CurrentPopulation Surveys. The data in this reportw,ie extracted from a series of tabulations pre-pared for and previously distributed by theOffice of Economic Opportunity (OEO). Theysupplement the data on the low-income populationalready published in other Series P-60 reports.Financial support for the preparation of thisreport was provided by the Office of AssistantSecretary for Planning and Evaluation, Depart-ment of Health, Education, and Welfare.
Data are presented here on the low-incomestatus of p-rsons cross-classified by age, familystatus, raLe, sex, work experience, occupatic,n,industry, major activity during survey week,income of a specified type, and metropolitan-nonmetropol itan residence. Some of these datahave been included in recent Series P-60 reportson the low-income population; however, this isthe first time that they are being shown as ahistorical series. Data are also shown on resi-dence in the 10. Federal regions' and on thecharacteristics of persons between 100 and 125percent and 125 and 150 percent of the low-incomelevel; these data have not been published inthe P-60 reports. The forthcoming detailed reporton the low-income population based on the March1974 Current Population Survey will includecomparable data for the year 1973.
The data in this report are based on samplesurveys and so caution must be used whenmakingcomparisons. Apparent differences between fig-ures could be the result of sampling variabilityrather than true differences in the population. Seepage 55 for estimates and further explanation ofsampling variability. The sampling errors for
'The low-income threshold for a nonfarm familyof four was $4,275 in 1972, t4,137 in 1971, andt3,317 in 1966. See page 48 for a detailed ex-planation of the low-income definition.

the estimated number of persons below the low-income level in each of the 10 Federal regionsare relatively larger than those at the U.S. level.(See tables A-10, A-11, and A-12.)
In analyzing data on the low-income population,the following limitations should be noted. Thelow-income concept has been developed in orderto identify, in dollar terms, a minimum level ofincome adequacy for families of different types inkeeping with American consumption patterns.Based on an analysis of the percent of incomedevoted to food expenditures, an estimate wasdeveloped of the minimum cost at which anAmerican family, making average choices, canbe provided with a diet meeting recommendednutritional goals. Consequently, it is an overallstatistical yardstick which reflects the differentconsumption requirements of families of differentsize, taking into account family composition andfarm-nonfarm residence. Insofar as individualcircumstances or consumption patterns differ, thedollar value of the low-income threshold for agiven family size may not represent the moneyincome required by an individual family to main-tain a level of economic well-being equivalent toother families with similar incomes. For a de-tailed discussion of the low-income concept, seeCurrent Population Reports, Series P-60, No. 91,"Characteristics of the Low-Income Population:1972."

Current Population Survey Reports. A detailedexplanation of the low-income concept appears inCurrent Population Reports, Series P-23, No. 28,"Revision in Poverty Statistics, 1959 to 1968."
A detailed description of the original povertyindex developed by the Social Security Adminis-tration appears in the following articles by MollieOrshansky published in the Social SecurityBulletin: "Counting the Poor: Another Look atthe Poverty Profile,' January 1965, and in "Who'sWho Among the Poor: A Demographic View ofPoverty," July 1965.
Data on poverty based on the original povertydefinition appear in Current Population Reports,Series P-60, No, 54, "The Extent of Poverty inthe United States: 1959 to 1966." Comprehensivedata and analysis of poor persons and familiesbased on the revised definition of poverty appearin Series P-60, No. 68, "Poverty in the UnitedStates, 1959 to 1968;" P-60, No. 76; "24 MILLIONAMERICANS, Poverty in the United States: 1969;"P-60, No. 81, "Characteristics of the Low-IncomePopulation: 1970;" P-60, No. 86, "Characteristicsof the Low-Income Population: 1971;" and P-60,No. 91, "Characteristics of the Low-IncomePopulation: 1972." Data based on the CurrentPopulation Survey showing the distribution offamilies and persons, by income levels, appearin the other P-60 reports, the latest of whichis P-60, No. 90, "Money Income in 1972 ofFamilies and Persons in the United States.'
Decennial Census
Low-income data collected in the 1970 Censusof Population appear in a number of publishedreports. Selected characteristics of low-incomepersons, families, and unrelated individuals,for the United States, each of the States, counties,standard metropolitan statistical areas, urbanizedareas, and urban places are presented in 1970Census of Population, Vol. I, Characteristics ofthe Population, chapter C, "General Social andEconomic Characteristics." Statistics on low-income status in 1969 of persons and familiesby detailed characteristics, including cross-classifications by race, age, weeks worked,education, type of family, etc., are presentedin 1970 Census of Population, Vol. I, Character-istics of the Population, chapter D, "DetailedCharacteristics," for some or all of the followingareas: United States, each of the States, andstandard metropolitan statistical areas of 250,000inhabitants or more. Further information iscontained in Data Access Description No. 29,Collection, Evaluation, and Processing SeriesCEP-7, "Low- Income Data from the 1970 Census."
Cross-classifications of low-income status in1969 for persons and families by detailed social,economic, and housing characteristics are pre-sented in 1970 Census of Population, Volunie IIReport PC(2)- 9A, "Low- Income Population."Tables are generally for the United States,although some are repeated for regions andmetropolitan- nonmetropolitan residence. Data onthe social, economic, and housing characteristicsof the low-income population residing in poverty
areas in the 50 largest cities can be found in 1970Census of Population, Volume 11 Report PC(2)-9B,"Low- Income Areas in Large Cities," and Supple-mentary Report PC(S1)-56, "Selected Character-istics of the Population in Low-Income Areas ofLarge Cities."
Statistics on income in 1969 collected in theCurrent Population Survey of March 1970 differfrom data for that year from the 1970 censusdespite the fact that the same basic concept wasused in both instances. In the first place, thesurvey data exclude the institutional population andmost members of the Armed Forces living on post.These two groups were included in the census.Secondly, college students are generally enumer-ated at their own homes in the Current PopulationSurvey and classified as family members, butwere enumerated at their college residence in thecensus, usually as secondary individuals. Thirdly,the small group of Current Population Surveyenumerators was more experienced and had moreintensive training and supervision than the largenumber of temporary census enumerators andmay have more often obtained more accurateanswers from respondents. Furthermore, ap-proximately 60 percent of the households wereself-enumerated in the 1970 census. Moreover,income data in the Current Population Survey arebased on responses to separate questions on eighttypes of income, as well as responses to additionalyes-no circles within 3 of these questions, whereasin the census only six questions were used,
In general, the number of persons and familiesbelow the low- income level reported in the censusis higher than that reported in the Current Popu-
3
lation Survey. The number of poor persons in the1970 census was 27.1 million compared to 24.1million derived from the March 1970 CurrentPopulation Survey. The comparable figures forlow-income families were 5.5 million and 5.0million, respectively.
For a more detailed discussion of the overallincome differences between the 197C -.ensus andthe Current Population Survey, see "PreliminaryEvaluation of 1969 Money Income Data Collectedin the 1970 Census of Population and Housing"by Mitsuo Ono, American Statistical AssociationProceedings of the Social Statistics Section, 1972.
Comparability of Data in Detailed Tablesof This Report With Corresponding Data
in Series P-60, Nos. 86 and 91
Data in this report differ from those in otherSeries P-60 reports in the following ways:
1, In this report, persons are classified bytheir own race, rather than by the race of thefamily head.
2. Data for income years 1969 and 1970are based on 1960 census population controlsand therefore differ from those shown in P-60,Nos. 86 and 91, which are b?sed on 1970 censuspopulation controls.
Also note that the source of the underlying0E0 tabulation for each detailed table in thisreport is listed on page 61 of appendix B.

APPENDIX t
DEFINITIONS AND EXPLANATIONS
Population coverage. This report excludes in-mates of institutions and unrelated individualsunder 14 years old. It .includes only those ap-proximately 1.0 million members of the ArmedForces living off post or with their families onpost. Since the original 0E0 tabulations includeunrelated individuals under 14 years, counts ofthese persons are presented in Table A-1.
Farm-nonfarm residence. The farm popula-tion refers to rural residents living on farms.The method of determining farm-nonfarm res-idence in the present survey is the same as thatused in the 1960 and 1970 censuses and in theCurrent Population Surveys since 1960, but differsfrom that used in earlier surveys and censuses.According to the current definitions, the farmpopulation consists of all persons living in ruralterritory on places of less than 10 acres yieldingagricultural products which sold for $250 or morein the previous year, or on places of 10 acresor more yielding agricultural products whichsold for $50 or more in the previous year. Ruralpersons in institutions, motels, and tourist camps,
and those living on rented places where no landis used for farming are not classified as farmpopulation.
The nonfarm population, as the term is usedhere, comprises persons living in urban areas andrural persons not on farms.
Metropolitan-nonmetropolitan residence. Thepopulation residing in standard metropolitan sta-tistical areas (SMSA's) constitutes the met-ropolitan population. Except in New England, anSMSA is a county or group of contiguous countieswhich contains at least one city of 50,000 inhab-itants or more, or "twin ( ities" with a combinedpopulation of at least 50,000. In addition to thecounty or counties containing such a city or cities,contiguous counties are included in an SMSA if,according to certain criteria, they are essentiallymetropolitan in character and are socially andeconomically integrated with the central city. InNew England, SMSA's consist of towns and cities,rather than counties,
The 1972 and the revised 1971 figures shown inthis report for SMSA's are based on the SMSA'sas defined on the basis of the 1970 census. Data

Note: Unrelated individuals under 14 years old are not classified by poverty status; they are allconsidered below the low-income level by definition. Questions on income are only asked of persons14 years old and over; consequently, unrelated individuals under 14 years have neither family income nor
incomes of their own.

Income. For each person 14 years old andover in the sample, questions were asked on theamount of money income received in the precedingcalendar year from each of the following sources:(1) Money wages or salary; (2) net income fromnonfarm self-employment; (3) net income fromfarm self-employment; (4) Social Security; (5)dividends, interest (on savings or bonds), incomefrom estates or trusts or net rental income;(6) public assistance or welfare payments; (7)unemployment and workmen's compensation, gov-ernment employee pensions, or veterans' pay-ments; (8) private pensions, annuities, alimony,regular contributions from persons not living inthis household, net royalties, and other periodicincome.
When an indefinite amount was reported by therespondent, a specific value was assigned duringprocessing wherever possible. If the indefiniteamount was reported in terms of a range, themidpoint of the range was assigned, e.g., $10,000to $15,000 was coded as $12,500. Open-endedamounts were converted to designated specificamounts, e.g., over $10,000 was coded as $15.000.
It should be noted that although the incomestatistics refer to receipts during the precedingyear the characteristics of the person, such as age,labor force status, etc., and the composition offamilies refer to the time of the survey. Theincome of the family does not include amountsreceived by persons who were members of thefamily during all or part of the income year ifthese persons no longer resided with the family atthe time of enumeration. On the other hand, familyincome includes amounts reported by relatedpersons who did not reside with the family duringthe income year but who were members of thefamily at the time of enumeration.
Data on income collected in the CPS are limitedto money income received before payments forpersonal income taxes, Social Security, uniondues, Medicare deductions, etc. Money income isthe sum of the amounts received from earnings;Social Security and public assistance payments;dividends, interest, and rent; unemployment andworkmen's compensation; government and privateemployee pensions; and other periodic income.(Certain money receipts such as capital gainsare not included.) Therefore, money income doesnot reflect the fact that many families receivepart of their income in the form of nonmoneytransfers such as food stamps, health benefits,2nd subsidized housing; that many farm familiesreceive nonmoney income in the form of rent-free housing and goods produced and consumedon the farm; or that nonmoney incomes are also
46
received by some nonfarm residents which oftentake the form of the use of business transportationand facilities, full or partial payments by businessfor retirement programs, medical and educationalexpenses, etc.' These elements should beconsidered when comparing income levels. More-over, readers should be aware that for manydifferent reasons there is a tendency in house-hold surveys for respondents to underreport theirincome. Overall aggregate income compiled inthe CPS was about 90 percent of benchmarkestimates in 1972. From an analysis of independ-ently derived income estimates, it has beendetermined that wages and salaries tend to bemuch better reported than such income types aspublic assistance, Social Security, and net incomefrom interest, dividends, rentals, etc.
Money wages or salary is total money earn-ings received for work performed as an employeeduring the income year. It includes wages, salary,Armed Forces pay, commissions, tips, piece-ratepayments, and cash bonuses earned, before de-ductions were made for taxes, bonds, pensions,union dues, etc.
Net income from nonfarm self-employmentis net money income (gross receipts minusexpenses) from one's own business, professionalenterprise, or partnership. Gross receipts in-clude the value of all goods sold and servicesrendered. Expenses include costs of goods pur-chased, rent, heat, light, power, depreciationcharges, wages and salaries paid, business taxes(not personal income taxes), etc. The value ofsalable merchandise consumed by the proprietorsof retail stores is not included as part of netincome.
Net income from farm self-employment isnet money income (gross receipts minus operatingexpenses) from the operation of a farm by a personon his own account, as an owner, renter, or share-cropper. Gross receipts include the value of allproducts sold, government crop loans, moneyreceived from the rental of farm equipment toothers, and incidental receipts from the sale ofwood, sand, gravel, etc. Operating expenses in-

It should be notedthat federal outlays for in-kind benefits, whichin table 558 include "Medicaid" and "Medicare"-inaddition to "Income security in kind", cannot beequated to increases in consumer income becausethey do not necessarily release equivalent amountsof funds for either consumption or savings.
elude cost of feed, fertilizer, seed, and otherfarming supplies, cash wages paid to farmhands,depreciation charges, cash rent, interest on farmmortgages, farm building repairs, farm taxes (notState and Federal income taxes), etc. The valueof fuel, food, or other farm products used forfamily living is not included as part of net income.In genera 1, inventory changes were not consideredin determining net income; however, replies basedon income tax returns or other official records doreflect inventory changes.
Social Security includes Social Security pen-sions and survivors' benefits, and permanent dis-ability insurance payments made by the SocialSecurity Administration prior to deductions formedical insurance and railroad retirement in-surance checks from the U.S. Government."Medicare" reimbursements are not included.
Dividends, interest (on savings or bonds),i:,come from estates or trusts, net rental incomeor net royalties include dividends from stock-holdings or membership in associations, intereston savings or bonds, periodic receipts fromestates or trust funds, net income from rentalof a house, store, or other property to others,receipts from boarders or lodgers, and netroyalties.
Public assistance or welfare paymentsinclude public assistance payments such as old-ageassistance, aid to families with dependent children,and aid to the blind or totally disabled. Separatepayments received for hospital or other medicalcare (vendor payments) are excluded from thisitem.
Unemployment compensation, governmentemployee pensions, or veterans' payments in-clude: (I) Unemployment compensation receivedfrom government unemployment insuranceagencies or private companies during periods ofunemployment and any strike benefits receivedfrom union funds; (2) government employee pen-sions received from retirement pensions paid byFederal, State, county, or other governmentalagencies to former employees (including membersof the Armed Forces) or their survivors; (3)money paid periodically by the Veterans' Ad-ministration to disabled members of the ArmedForces or to survivors of deceased veterans,subsistence allowances paid to veterans foreducation and on-the-job training, as well asso-called "refunds" paid to ex-servicemen asGI insurance premiums; also includes (4) work-men's compensation received periodically frompublic or private insurance companies for injuriesincurred at work. The cost of this insurance musthave been paid by the employer and not by theperson.
Private pensions, annuities, alimony, reg-ular contributions from persons not living in thehousehold, and other periodic income include thefollowing types of income: (1) Private pensionsor retirement benefits paid to a retired personor his survivors by a former employer or by aunion, either directly or through an insurancecompany; (2) periodic receipts from annuities orinsurance; (3) alimony and child support; (4)contributions 1eceived periodically from personsnot living in the household; and (5) other periodicincome such as military family allotments, netgambling winnings, and other kinds of periodicincome other than earnings.
Receipts not counted as income. Receipts fromthe following sources were not included as income:(1) Money received from the sale of property, suchas stocks, bonds, a house, or a car (unless theperson was engaged in the business of selling suchproperty, in which case the net proceeds would becounted as income from self-employment); (2)withdrawals of bank deposits; (3) money borrowed;(4) tax refunds; (5) gifts; and (6) lump sum in-heritances or insurance payments.
All sources of income may be combined intotwo major types:
Total money earnings--the algebraic sumof money wages or salary and net income fromfarm and nonfarm self-employment; and
Income other than earnings--the algebraicsum of all sources of money income except wagesand salaries and income from self-employment.
Total money income. The algebraic sum ofmoney wages and salaries, net income from self-employment, and income other than earningsrepresents total money income. The total incomeof a family is the algebraic sum of the amountsreceived by all income recipients in the family.
The low-income data for families and unrelatedindividuals include those that were classified ashaving no income in the income year and thosereporting a loss in net income from farm andnonfarm self-employment or in rental income.Many of these were living on income "in kind,"savings, or gifts; or were newly constitutedfamilies, unrelated individuals who had recentlyleft families, or families in which the solebreadwinner had recently died or had left thehousehold. However, many of the families andunrelated individuals who reported no incomeprobably had some money income which was notrecorded in the survey.
4/Median income. The median income is the
amount which divides the distribution into twoequal groups, one having incomes above themedian, and the other having incomes below themedian.
Mean income. The mean income is the amountobtained by dividing the total income of a group bythe number of families or unrelated individuals(as appropriate) in that group.
Comparability of Current Population Surveyincome data with other data from Bureau ofEconomic Analysis (BEA) personal income series.
e income ata presentee in this report are notdirectly comparable with estimates of aggregatepersonal income prepared by the Bureau ofEconomic Analysis (formerly the Office ofBusiness Economics) of the Department of Com-merce. The lack of correspondence stems fromthe following differences in definition and cov-erage:
Income definition. The personal income seriesincludes, among other items, the following typesof nonmoney income which are not included in thecensus definition: Wages received in kind, thevalue of food and fuel produced and consumed onfarms, the net rental value of owner-occupiedhomes, the property income received by mutuallife insurance companies, and the value of theservices of banks and other financial inter-mediaries rendered to persons without the as-sessment of specific charges. These items ofincome in kind account for about 4 percent oftotal personal income. The Census Bureau defi-nition of income, on the other hand, includes suchitems as regular contributions for support re-ceived from persons who do not reside in the sameliving quarters, income received from roomersand boarders residing in households, and em-ployee contributions for social insurance whichare not included in the personal income series.These items, however, represent a much smallerincome total than the nonmoney items includedin personal income.
Source of data. The personal income seriesis estimated largely on the basis of data derivedfrom business and governmental sources. Thesesources include the industrial and populationcensuses, employers' wage reports under theSocial Security programs, and records of dis-bursements to individuals by governmentalagencies. The income data presented in the censusreports, on the other hand, are based directly onfield surveys of households. As discussed inthe section "Source and reliability of the esti-mates," income data obtained in household inter-views are subject to various types of reporting
48
errors which tend to produce an understatementof income. It is estimated that the income surveysconducted by the Bureau of the Census during thepast few years have obtained about 89 percent ofthe comparable aggregate total money income, 97percent of the comparable aggregate money wageor salary income, 84 percent of the comparableaggregate money Social Security income, and 73percent of the comparable aggregate money publicassistance income included in the personal in-come series prepared by the BEA. Comparableestimates are not available for the low-incomepopulation.
Low-Income (poverty) definition. Low-incomestatistics presented in this report are based ona definition developed by the Social SecurityAdministration in 1964 and revised by a FederalInteragency Committee in 1969.
Statistics presented in Census Bureau reportsprior to publication of Current Population Reports,Series P-60, No. 68, "Poverty in the United States,1959 to 1968," were based on the poverty indexdeveloped by the Social Security Administration(SSA) in 1964. This index provided a range ofincome cutoffs adjusted by such factors as familysize, sex of the family head, number of childrenunder 18 years old, and farm-nonfarm residence.At the core of this definition of poverty was anutritionally adequate food plan ("economy" plan)designed by the Department of Agriculture for"emergency or temporary use when funds arelow." The SSA poverty cutoffs also took intoaccount differences in the cost of living betweenfarm and nonfarm families. Annual revisions ofthese cutoffs were based on price changes ofthe items in the economy food budget.
As a result of deliberations of a Federal In-teragency Committee in 1969, the following twomodifications to the original SSA definition ofpoverty were recommended: (1) that the SSAthresholds for nonfarm families be retained forthe base year 1963, but that an:.ual adjustmentsin the levels be based on changes in the ConsumerPrice Index (CPI) rather than on changes in thecost of food included in the economy food plan;and (2) that the farm thresholds be raised from70 to 85 percent of the corresponding nonfarmlevels. The combined impact of these twomodifications resulted in an increase of 360,000poor families and 1.6 million poor persons in 1967.The reasons for making these changes are outlinedbelow.
Change in cost of living adjustment. Annualrevisions of the SSA poverty thresholds were basedonly on the average per capita cost of the foods
in the economy food budget. This method of up-dating these cutoffs did not fully reflect increasesin the overall cost of living during the 1960's.The pace at which the general cost of livingadvanced in recent years was not uniformlymatched by increases in the price of goods inthe economy food plan. Thus, general pricechanges since 1959 were not paralleled by com-parable changes in the poverty thresholds.
The differences between changes in the costof the economy food budget and the overall costof living led to the adoption of the CPI as thebasis for annual revisions in the income cutoffs.Although the CPI is not designed to measure thechanging market conditions faced solely by low-income families, it does reflect the fact thatprices of food and nonfood commodities do notalways advance at the same rate. Employing theCPI to adjust the low-income thresholds annuallyhas another advantage over the earlier adjustmenttechnique. Although the economy food plan isrepriced annually, the data are not publishedregularly but are available only on request. TheCPI, on the other hand, is regularly publishedand is a generally accepted measure of changes inthe "cost of living." Table A-2 shows the changesin the CPI between 1966 and 1972 and thecorresponding average thresholds for a nonfarmfamily of four.

Change in the farm-nonfarm relationship.Under the old definition, the poverty thresholds forfarm families were adjusted for the average valueof food consumed by these families which theyhad grown themselves. Based on a 1961 study ofhousehold consumption which indicated that thevalue of food produced by farm families for homeuse amounted to about 30 percent of their totalfood budget, the poverty cutoffs for farm familieswere established at 70 percent of the nonfarmlevels.
Up to the present time, no entirely satis-factory means of determining the income re-quired for equivalent levels of living for farmand nonfarm families has been provided by studieson this subject. Further research is needed toanalyze the differences in the costs between farmand nonfarm families. Although it is not yetpossible to quantify exactly all the factors con-tributing to cost of living differences betwegnfarm and nonfarm families, research alreadycompleted suggests that the differences are notas great as provided for by the 70 percentdifferential. After weighing the available evi-dence, the Review Committee agreed that nar-rowing the farm-nonfarm differentia I to 85 percentmore nearly reflects the overall cost of livingdifferences between farm and nonfarm familiesthan the previously used differential.
Alternate levels. Because the low-incomelevel currently in use by the Federal Governmentdoes not meet all the needs of the analysts of thedata, two variations of the poverty definition arepresented in this report, one set at 125 percent ofthe official government standard and the other at150 percent of this standard. The alternate cut-offs are obtained by multiplying the income cut-offs at the low-income level by 1.25 and 1.50.Thus, the income cutoffs in 1972 for a nonfarmfamily of four at 125 percent and 150 percent ofthe low-income level were $5,344 and $6,413,respectively.
Weighted average thresholds at the low- incomelevel. The low-income cutoffs used by the Bureauof the Census to determine the low-income statusof families and unrelated individuals consist of aset of 124 thresholds arranged in a four-dimensional matrix consisting of family size(from one person, i.e., unrelated individuals, toseven or more person families) cross-classifiedby presence and number of family members under18 years old (from no children present to six ormore children present), sex of head, and farm-nonfarm residence. Unrelated individuals andtwo-person families are further differentiated byage of head (under 65 years and 65 years andover). The total family income of each family inthe sample is tested against the appropriatedollar threshold to determine the low-incomestatus of that family. If the family's total incomeis less than its corresponding cutoff, the familyis classified as below the low-income level. Theaverage thresholds shown in table A-3 wereweighted by the presence and number of children.For example, for a given size of family, sex ofhead, and residence category, the weightedaverage threshold for that group is obtained bymultiplying the threshold for eacii presence andnumber of children category within the given
49
family size by the number of families in thatcategory. These products are then aggregatedacross the entire range of presence and numberof children categories, and the total aggregateis divided by the total number of families in thegroup to yield the weighted average threshold atthe low-income level for that size family.
Because family composition varies by .farm-nonfarm residence, the weighted average thresh-olds at the low-income level for farm families,as shown in table A-3 will not be exactly 85 per-cent of the nonfarm levels. Moreover, since fam ilycomposition does not remain constant from year toyear, the weighted average thresholds for 1972will not reflect, identically, the change in the CPIbetween 1972 and earlier years.
Family. The term "family,* as used in thisreport, refers to a group of two or more personsrelated by blood, marriage, or adoption andresiding together; all such persons are consideredas members of the same family. Thus, if the sonof the head of the household and the son's wifeare in the household, they are treated as part ofthe head's family. On the other hand, a lodgerand his wife not related to the head of the house-hold or an unrelated servant and his wife areconsidered as additional families, and not a partof the household head's family.
Since the basic thresholds used to determinethe low-income status of families and unrelatedindividuals are applied to all families and un-related individuals, the weighted low-incomethresholds are derived using all families andunrelated individuals rather than just those fam-ilies and unrelated individuals classified as belowthe low-income level. To obtain the weightedlow-income thresholds for families and unrelatedindividuals below 125 percent and below 150 per-cent of the low-income level, the weighted thresh-olds shown in table A-3 may be multiplied directlyby 1.25 and 1.50, respectively.
Head of family. One person in each family wasdesignated as the head. The head of a family isusually the person regarded as the head by mem-bers of the family. Women are not classified asheads if their husbands are resident members ofthe family at the time of the survey. Marriedcouples related to the head of a family are in-cluded in the head's family and are not classifiedas separate families.
Size cf. family. The term "size of family'refers to the number of persons who are livingtogether and are related to each other by blood,marriage, or adoption.
50
Table A-3. WEIGHTED AVERAGE THRESHOLDS AT THE LOW-INCOME LEVEL IN 1972 BY SIZE OF FAMILY ANDSEX OF HEAD, BY FARM-NONFARM RESIDENCE
'For unrelated individuals, sex of the individual.
Unrelated individual. The term "unrelated in-dividuals as used in this report, refers topersons 14 years old and over (other than in-mates of institutions) who are not living with anyrelatives. An unrelated individual may constitutea one-person household by himself, or he may bepart of a household including one or more otherfamilies or unrelated individuals, or he mayreside in group quarters such as a rooming house.Fhus, a widow living by herself or with one ormore other persons not related to her, a lodgernot related to the head of the household or to any-one else in the household, and a servant living inan employer's household with no relatives areexamples of unrelated individuals.
Related children. "Related" children in afan include own children and all other childrenin the household who are related to the familyhead by blood, r-!-!~riagc, or adoption. In thisreport, the small number of family heads andwives 14 and 15 'ears old are included with thecount of related children under 1R.
Age. The age classification is based on theagt7r) The person at his last birthday.
Race. population is divided into threegroups on the basis of race: white, Negro, and"other races." The last category includes In-dians, Japanese, Chinese, and any other raceexcept white and Negro,
In this report, persons are classified bytheir own race rather than the race of the familyhead as in other Series 1' -60 reports. Thedifferences are negligible for both the poor andthe total population.
Years of school completed. Data on years ofschool completed in this report were derivedfrom the combination of answers to questions con-cerning the highest grade of school attended bythe person and whether or not that grade wasfinished. The questions on educational attain-ment apply only to progress in "regular" schools.Such schools include graded public, private, andparochial elementary and high schools (bothjunior and senior high), colleges, universities,and professional schools, whether day schoolsor night schools. Thus, regular schooling isthat which may advance a person toward anelementary school certificate or a high schooldiploma, or a college, university, or professionalschool degree. Schooling in other than regularschools was counted only if the credits obtainedwere regarded as transferable to a school in theregular school system.
The median years of school completed isdefined as the value which divides the distributioninto two equal groups, one havingcompleted moreschooling and one having completed less schoolingthan the median. These medians are expressedin terms of a continuous series of numbersrepresenting years of school completed. Forexample, a median of 9.0 represents the com-pletion of the first year of high school and amedian of 13.0 means completion of the firstyear of college.
Labor force and employment status. Thedefinitions of labor force and employment statusin this report relate to family heads and un-related individuals 14 years old and over.
Employed. Employed persons comprise (1)all civilians who, during the specified week, didany work at all as paid employees or in theirown business or profession, or on their ownfarm,or who worked 15 hours or more as unpaidworkers on a farm or in a business operated bya member of the family, and (21 all those whowere not working but who had jobs or businessesfrom which they were temporarily absent becauseof illness, bad weather, vacation, or labor-management dispute, or because they were takingtime off for personal reasons, whether or notthey were paid by their employers for time off,and whether or not they were seeking other jobs.Excluded from the employed group are personswhose only activity consisted of work around thehouse (such as own home housework, painting orrepairing own home, etc.) or volunteer work forreligious, charitable, and similar organizations.
Unemployed. Unemployed persons arethose civilians who, during the survey week, hadno employment but were available for work and(11 had engaged in any specific jobseeking ac-tivity within the past 4 weeks, such as registeringat a public or private employment office, meetingwith prospective employers, checking with friendsor relatives, placing or answering advertise-ments, writing letters of application, or being ona union or professional register; (2) were waitingto be called back to a job from which they hadbeen laid off; or!(3) were waiting to report to anew wage or salary job within 30 days.
Labor force. Persons are classified as inthe labor force if they were employed as civilians,unemployed, or in the Armed Forces during thesurvey week. The "civilian labor force" is corn-prised of all civilians classified as employed orunemployed.
Not in the labor force. All civilians 14years old and over who are not classified asemployed or unemployed are 'efined as "not inthe labor force.* This group who are neitheremployed nor seeking work includes personsengaged only in own home housework, attendingschool, or unable to work because of long-termphysical or mental illness; persons who areretired or too old to work; seasonal workers forwhom the survey week fell in an off season; andthe voluntarily idle. Persons doing only unpaidfamily work Mess than 15 hours) are also classi-fied as not in the labor force.
Major activity in survey week. Persons areclassified by major activity in survey week basedon the response to the question, "What were youdoing most of last week?* In this report, theugly categories of major activity shown are"Going to school* and "Other."
51
Occupation, industry, and class of worker.Persons are classified according to tie civilianjob held longest during the year. Persons whoheld two jobs or more were reported in the jobat which they worked the greatest number ofweeks.
The occupation and industry groupings in-cluded in this report were based on the classi-fication systems used in 1960 census. Dataincluded in Series P-60, Nos. 81, 86, and 91 forthe years 1970 to 1972 were based on the classi-fication systems used in the 1970 census. Adetailed comparison of the 1970 classificationsystems to those used during the 1960's may befound in the Bureau of the Census TechnicalPaper 26, 1570 Occupation and Industry Classi-fication Systems in Terms of Their 1960 Occu-pation and industry Elements.
In addition to the change in occupationaltitles between the March 1972 and the March1971 surveys which did not affect the com-parability of the data, a supplemental question,"What were your most important activities orduties?" was added which provided additionalinformation for classifying persons by occupation.In general, the major impact of this supplementalquestion was to reclassify some persons from the"managers" classification into other types ofoccupations (primarily into the major occupationgroup of "craftsmen").
Class of worker refers to the subdivision ofworkers into three groups: Wage and salaryworkers, self-employed workers, and unpaidfamily workers. The first group refers topersons working for wages, salaries, commis-sions, tips, pay "in kind", or at piece rate forprivate employer or for any government unit.The second group refers to persons working intheir own business, profession, or trade, forprofit or fees. The third group refers to personsworking without pay in a business operated by amember of the household to whom they are re-lated by blood or marriage.
Work experience. A person with work ex-perience is one who, during the preceding calen-dar year, did any civilian work for pay or profitor worked without pay on a family-operated farmor business at any time during the year, on apart-time or full-time basis.
Weeks worked in the income year. PersonsareElissified according to the number of differentweeks during the preceding calendar year in whichthey did any civilian work for pay or profit (in-cluding paid vacations and sick leave; or workedwithout pay on a family-operated farm or business.
52
Part-time or full-time jobs. A person isclassified as having worked at part-time jobsduring the preceding calendar year if :le workedat civilian jobs which provided less than 35 hoursof work per week in a majority of the weeks inwhich he worked during the year. He is classifiedas having worked at full-time jobs if he worked35 hours or more per week during a majority ofthe weeks in which he worked.
Year-round full-time worker. A year -roundfull-time worker is one who worked primarily atfull-time civilian jobs (35 hours or more perweek) for 50 weeks or more during the precedingcalendar year.
Nonworker. A nonworker is one who did notdo any civilian work in the calendar year pre-ceding tne survey.
Main reason for working part year. Forpersons who worked 1 to 49 weeks wring theyear, the main reason for working part year isbased on the response to the question "What wereyou doing most of the remaining weeks?"
Niain reason for not working. For persons whoreported that they did not work at a civilian jobfor pay or profit or on a family-. perated farmor business during the year, the main reasonfor not working is derived from the responseto the question "What were you doing most oflast year ?'
Rounding. Percentages are rounded to thenearest tenth of a percent; therefore, the per-centages in a distribution do not always add toexactly 100.0 percent. The totals, however, arealways shown as 100.0. Moreover, individualfigures are rounded to the nearest thousandwithout being adjusted to group totals, which areindependently rounded; Percentages are based onthe unrounded numbers.
Base figures. An estimate of the size of thebase (number of persons and families, etc.) ofeach percent is shown, in most of the tables ofthis report. The 1P72 and 1971 base figuresshown in this report were prepared by inflatingweighted sample results to agree with independentestimates of the population based on statisticsupdated from the 1970 census. The base tiguresfor the years 1966 to 1970 were inflated to esti-mates derived from the 1960 census.
The major effects resulting from the intro-duction of population controls and estimationprocedures based on the 1970 census were to
raise the number of families from 51.2 millionto 51.6 million in the March 1970 CPS and tolower the number of related children under 18from 69.8 to 63.7 million. However, the numberof poor families and the number of related chil-dren below the low-income level remained aboutthe same--5 million and about 9.5 million,respectively. Figures for 1969 and 1970 basedon 1970 census population controls are shownin Current Population Reports, Series P-60,No. 91.

The data for 1.972 and 1971 are in someinstances not entirely comparable to figures forearlier years because of revisions in the CurrentPopulation Survey. Starting in January 1972, 1970census-based population controls, metropolitanresidence definitions, and other materials wereintroduced into the sample and estimation pro-cedures. The major item affecting compar-ability at the overall national level is the intro-duction of population controls based on the 1970census. Figures for previous years are tied inwith 1960 census-based population controls.Basically, these changes should have no sub-stantial impact on summary measures, such asmedians and means, and on proportional measures,such as percent distributions and low-income orpoverty rates. However, the changes may havemore impact on the population levels in differentsubgroupings such as the total number of personsor families either overall, within some particularincome interval, or below the low-income level.A detailed description of these changes appearsin the Bureau of L abor Statistics report, "Employ-ment anci Earnings," Vol. 18, No. 8, February1972. In this report, data for 1969 and 1970 wereinflated to independent estimates of We populationbased on 1960 census data and, therefore, differsomewhat from those shown in the Series P-60reports, Nos. 86 and 91, which are based on 1970census controls.
The figures shown in this report for metro-politan areas (SMSA's) are based on the SMSA'sas defined on the basis of the 1970 census; thosepublished in earlier years referred to SMSA's asdefined on the basis of the 1960census. There aresignificant differences in the population classifiedas metropolitan from each of these definitions.For the 1970 definition of SMSA's, see U.S. Censusof Population: 1970, NUMBER OF INHABITANTS,PC(1)-Al, United States Summary.
NONRESPONSES AND ALLOCATIONS
In the March 1973 no information wasrecorded for approximately 5 percent of the47,000 households because 00 inter% iew couldbe obtained during di,. week in which the enu-meration was conducted. In ord..: to accountfor these households, the weights assigned toother sample households of similar character-istics residing in the same sam.ple areas wereincreased accordingly. In addition, completeincome information was not reported for about17 percent of all families and 12 percent ofunrelated individual, 14 years old or over.Overall, about 12 percent of all persons 14years old and ove: in households that wereinterviewed did not report complete incomeinformation.
or more detailed information on the char-acteristics of nonrespondents, see "Character-istics of Income Nonrespondents in the ( 'urrentPopulation surve\ ," I miner ,piers, JohnCoder, and Nlitsuo Ono, American statisticalAssociation Proceedings of the social statistics
In order that the maximum amount of informa-tion can he utilized, missing income items areimputed or allocated by values which are obtainedfrom active respondents with similar economicand demographic characteristics. Beginning withthe March 1962 survey, when a respondent did notanswer one or more of the income items, all ofhis income data were imputed.
Beginning with the March 1966 survey, how-ever, in the event a respondent did not answerone or more of the income questions, the mi :singincome data for this person were imputed foronly those income items which were not answered.bach of the earnings items was handled indivi-dually, whereas income items other than earningswere handled as a group. Characteristics usedin this imputation are age. family status, race,residence, weeks worked, and major occupationgroup. The income amount assigned to a non-respondent is that observed for another personwith similar demographic and economic charac-teristics who did respond and who has beenselected systematically in the order in whichindividual records are processed.
Beginning with the 1967 Cl's, the Bureau ofthe Census introduced improved income edit andallocation procedures. rile main feature of thenew procedures is a more refined method forimputing income data which expands theuse of information 'already known about that per-son. Among the major improvements made af-fecting the income data are the following (1) an
53
expanded set of social and economic characteris-tics within which the imputations are made; inaddition to age, race, occupation, and weeksworked, the new procedures include sex and typeof family member as major variables withinwhich the missing income items are imputed; (2)the elimination of inconsistent reporting whichresulted in having workers with no earnings andearners with no weeks worked; and (3) the newimputation procedure assigns missing earningsentries first and then utilizes the earnings in-formation to assi0 missing sources of incomeother than earning,.
I loever, because of coding errors in the proc-essing of the 1965 CPS data, in that year alone itwas not possible to apply all the aforementionedimprovements to the editing and allocation pro -cedures. Since these errors produced an under-estimate of income, they had the effect of over-estimating the number of poor.
In addition, it was discovered that the computerprocedures for editing certain incorrect incomecodes caused an upward bias in the income datafor some r,spondents and therefore would tendto produce an underestimate of the number ofpoor. It is estimated that the net impact of theseerrors had the effect of overestimating the num-ber of poor families by about 120 thousand. Dueto these errors affecting the income data for 1967,data for that year are not strictly comparablewith those shown for 1966, and 1965 to 1972.
Comparison of 1966 poverty data according toorialTEL 1-1 and- revised-editing and allocation pro-ced-ures. Tn or--der to evarirrte the impact of the newprocedures, the poverty data from the March 1967
w:re rerun, thus providing a bridge for the1966 income yl ar showing the results of both theearlier and the new procedures. Both ser'es ofdata are shown in table 1 of P-60, No, 91. Thegeneral impact of he new allocation procedurewas to shift the income distribution slightly up-ward, thus decreasing by 416,000 the number ofpoor families. A more detailed description ofthe new computer editing and allocation proceduresmay he found in Current Population Reports,Series P-60, No. 59, "Income in 1967 of Familiesin the United States," pages 17 to 19,
Modifications in collecting income data in theMarch-April 1969 CI'S. Several modificationswere introduced in the collection of income datain the March and April CPS supplements. Theseinclude (1) '_'Y.tcns ion of the interview period of thesix rotation groups for which income questionswere asked in March and the use of followup formsin these six groups to accommodate householdrespondents who needed more time to obtain therequired income information (it is estimated that
54
some members of approximately 4,400 house-holds, or 9 percent of the total relevant house-holds, made use of these followup forms); (2)modification of the design and content of thequestionnaire to allow for more detailed question-ing of certain income items; thus, boxes for grossreceipts, business expense, and net income havebeen added to the self-employment incomequestions to help the interviewer and respondentdetermine net income, and "yes-no" circleswere added to the questions on income other thanearnings in order to ascertain whether the re-spondent received or did not receive income;(3) field office editing procedures were extendedto a 100 percent income edit of the CPS schedules;(4) training instructions were strengthened byincluding more detailed explanations and moreexamples; and (5) the interview group trainingsession was shifted from February to March.
Modifications in collecting income data in theMarch 1970 Current Population Survey. TheBureau introduced modifications in the collectionof income data for the March 1970 CPS supplement.These were: (1) An advance letter informinghouseholds about the collection of income data wasmailed to all households except those in the firstand fifth months. The latter households receivedspecial letters which explained the need for col-lecting both CPS and census data; (2) informationon work experience and income was collectedsimultaneously for the full sample (in previousyears, work experience information was collectedseparately from income data); (3) the interviewperiod was extended one week for three-fourthsof the sample (using followup calls and separatequestionnaires). In addition, modified pro( ..dureswhich were incorporated in the March 1969 CPSsupplement were also implemented in the March1970 CPS. Overall, data indicate that the use ofthese procedures has resulted in some improve-ment in the collection of income data. Thefamily income nonresponse rate has not onlydropped by 5 percentage points (from 19 to 14percent) bur also it appears that the proportionof aggregate income amounts collected in theMarch 1970 CPS relative to benchmark totalshas increased slightly in the March 1970 CI'Ssupplement as compared with the proportioncollected in the March 1969 CPS supplement.
Modifications in collecting income data in theMarch 1971 Current Population Survey. theBureau continued to use the improved procedureswhich were incorporated in the March 1970 CPS.Procedural changes that were instituted in theMarch 1971 CPS, among others, were:
1. The interview period was extended oneweek for all households in the sample (usingfollowup calls and separate questionnaires). In
the previous year's survey, the interview periodwas extended for only three-fourths of thesample.
2. Income from net royalties was included inthe question covering estates, trusts, or dividends,interest on savings accounts or bonds, and netrental income. In previous surveys, income fromnet royalties was included in the question coveringprivate pensions, annuities, alimony, regularcontributions from persons not living in thishousehold, and anything else.
3. An additional regional office followupwas made by telephone to obtain income amountsfor all followup cases containing one or morepersons who were not interviewed during theoriginal followup period, except for refusal.
Overall, the family income nonresponse ratein March 1973 was 16.5 percent as compared to13.7 percent in March 1972. The proportion ofaggregate income amounts collected in the March1973 CI'S relative to benchmark totals was aboutthe same as for the March 1972 CPS.
Although nonresponse rates for families bylow-income status are not available, it is knownthat families in the low._ r income intervals tendto have lower nonresponse rates than those inthe middle and upper income intervals. This isdue in part to the fact that lower income familieshave less complicated financial arrangementsthan those in other income groups. For a moredetailed discussion of this topic see paper byMitsuo Ono and Herman P. Miller, "IncomeNonresponses in the Current Population Survey,"published in Proceedings of the Social StatisticsSection, American Statistical Association, 1969.
OTHER LIMITATIONS OF THE DATA
It is known that income data are usually under-reported in household surveys, such as the CurrentPopulation Survey (CPS), when compared withaggregate benchmark estimates derived fromadministrative records.
As noted previously, overall aggregate moneyincome compiled in the CI'S was about 90percentof benchmark estimates in 1972. The proportionof aggregate income compiled in the CI'S rangedfrom a low of 45 percent for property income toa high of 98 percent for wage and salary income.The proportion picked up for Social Security andrailroad retirement payments was 92 percentwhile the comparable rate for public assistancewas 74 percent. These rates were 99 and 69percent for nonfarm and farm self-employment
income, respectively. Benchmark estimates arccompiled from data provided by the Bureau ofEconomic Analysis, Social Security Administra-tion, Veterans' Administration, etc. For moredetails regarding the procedures to developbenchmark data, see thefollowing: (1) "Appraisalof Basic Data :Walkable for Constructing IncomeSize Distribution? by Selma F. Goldsmith, pub-lished in Studies in Income and Wealth, Volume 13,National Bureau of Economic Research, 1951 and(2) "Size Distribution of Family Personal Income:Methodology and Estimates for 1964," byEdward C. Budd, Daniel B. Radner, and ,lohn C.Hinrichs, Bureau of Economic Analysis, BEA-SP73-21, June 1973.
Although every effort is made to reduce theerrors of underreporting, nonreporting or mis-reporting of income data in the Current PopulationSurvey, they still occur because of various rea-sons. Some of these are (I) overlooking incomereceived, especially small amounts of incometypes not regularly received, e.g., contributionsfrom nonhousehold members, (2) reluctance toreveal certain types of income, e.g., publicassistance, (3) rounding estimates, (4)misunder-standing the question, (5) lack of information,especially covering family members not presentat the time of interview, (6) interviewers' errors,(7) processing errors, etc. For more details onthis topic of income underreporting in censusesand surveys, see (I) Income Distribution in theUnited States (a 1960 Census Monograph), byHerman P. Miller, Bureau of the Census, 1966,(2) The Structure of Income, by Irving 13. Kravis,University of Pennsylvania, 1962, and (3) "SizeDistribution of Family Personal Income: Metho-dology and Estimates for 1964" cited earlier inthis section.
SOURCE AND RELIABILITY OFTHE ESTIMATES
Source of data, The estimates for 1966through 1972 are based on data obtainec eachMarch of the years 1967 through 1973 in theCurrent Population Survey (CPS) of the Bureauof the Census. In March 1973 the sample wasspread over 461 areas comprising 923 countiesand independent cities with coverage in eachof the 50 States and the District of Columbia.As of July 1971 approximately 47,000 occupiedhouseholds have been eligible for interview eachmonth. Of this number 2,000 occupied units,on the average, were visited but interviewswere not obtained because the occupants were notfound at home after repeated calls or wereunavailable for some other reason. In additionto the 47,000, there were also about 8,000 sampleunits in an average month which were visited butwere found to be vacant or otherwise not to be
55
interviewed. From January 1967 through July1972 the sample was spread over 449 areas,and from January 1967 through June 1971 ap-proximately 50,000 occupied housing units wereeligible for interview each month. See CurrentPopulation Reports, Series P-23, No. 22,"Concepts . and Methods Used in ManpowerStatistics from the Current Population Survey,"June 1967, pp. 7-10, for more information aboutthe sample design.
The estimating procedure used for the CPSdata involved the inflation of the weighted sampleresults to independent estimates of the civiliannoninstitutional population of the United Statesby age, race, and sex for March 1972 andMarch 1973. These independent estimates werebased on statistics from the 1970 Census ofPopulation; statistics of births, deaths, immi-gration and emigration; and statistics on thestrength of the Armed Forces. To these totalswere added the population in the Armed Forcesliving off post or with their families on post.
For data collected in the March CurrentPopulation Surveys in the years 1967-71 theindependent estimates used were based onstatistics from the 1960 Census of Population.Current Population Reports, Series P-60,Numbers 86 and 91 showed somewhat differentfigures for 1969 and 1970 since the data inthose reports were inflated to independentestimates of the population based on 1970census data. The 1972 and 1971 data by residenceare based on the 1970 census residence de-finition; therefore, they are not strictly com-parable to data for earlier years which arc basedon 1%0 census metropolitan area definition.
Reliability of the estimates. Since theestimates in this report are based on a sample,they differ somewhat from the figures thatwould have been obtained from a complete census,using the same schedules, instructions, andenumerators. Particular care should be exercisedin the interpretation of figures based on arelatively small number of cases as well as smalldifferences between figures. As in any surveywork, the results are subject to errors ofresponse and non-reporting as well as beingsubject to sampling variability.
In most cases, the schedule entries for incomeare based on memory rather than on records,and, in the majority of cases, on the memoryor knowledge of one person, usually the wifeof the family head. The memory factor in dataderived from field surveys of income producesunderestimates because the tendency is to forget
56
minor or irregular sources of income. Theseerrors of reporting are due to misrepresentationor to misunderstanding as to the scope of theincome concept.
The standard error is primarily a measureof sampling variability, that is, of the variationsthat occur by chance because a sample ratherthan the whole of the population is surveyed.As calculated for this report, the standarderror also partially measures the effect ofresponse and enumeration errors, but it doesnot measure, as such, any systematic biasesin the data. The chances are about 68 out of100 that an estimate from the sample woulddiffer from a complete census figure by lessthan the standard error. The chances areabout 90 out of 100 that this difference wouldbe less than 1.6 times the standard error,and the chances are about 05 out of 100 thatthe different %. would he less than twice thestandard error.
Fhe figures presented in tables A-4 throughA-12 are approximations to the standard errorsof various estimates shown in this report. In
order to derive standard errors that would beapplicable to a wide variety of items and couldbe prepared at a moderate cost, a number ofapproximations were required. As a result,the tables of standard errors provided are anindication of the order of magnitude ratherthan the precise standard error for any specificitem.

The reliability of. an estimated percentage,computed by using sample data for both numerator
and denominator, depends upon both the sizeof the percentage -nd the size of the total upon
which the percentage is based. Estimated per-centages are relatively more reliable than thecorresponding absolute estimates of the numer-ator of the percentage, particularly if the percentis 50 percent or more.

Table A-8 shows the standard errors ofestimated percentages of low-income personsfor the years 1966-1972. Table A-9 showsthe standard errors of estimated percentagesof low-income families for the years 19661972.The same standard errors can be used forpercentages of total families. The guidelinesused to decide whether tables A-4, A-5, A-6,or A-7 are appropriate for a particular itemshould also be used for deciding between the useof tables A-8 and A-9. Tables A-11 and A-12contain the standard errors of estimated per-centages for the 10 Federal regions.
57
Note when using small estimates. Percentagedistributions are shown in this report only whenthe base of the percentage is greater than 75,000.
Because of the large standard errors involved,there is little chance that percentages wouldreveal useful information when computed on asmaller base. Estimated totals are shown,however, even though the relative standard errorsof these totals are larger than those for thecorresponding percentages. These smallerestimates are provided primarily to permitsuch combinations of the categories as serveeach user's needs.
Differences. For a difference between twosample estimates, the standard error is approxi-mately equal to the square root of the sum ofthe squares of the standard errors of eachestimate considered separately. This formulawill represent the actual standard error quiteaccurately for the difference between twoestimates of the same characteristic in twodifterent areas, or for the difference betweenseparate and uncorrelated characteristics ?nthe same area. If, however, there is a highpositive correlation between the two character-istics, the formula will overstate the true standarderror.
Table A-8. STANDARD ERRORS OF ESTIMATED PERCENTAGES OF LOW-INCOME PERSONS FOR 1966 TO 1972
Illustration of the use of tables of standarderrors for national estimates. 'Fable 8 of thisreport shows that in 1972 there were 1,092,000total female headed families with income fromearnings below the low-income level. -FableA-5 shows the standard error on an estimateof this size to be approximately 32,000. Thechances are 6S out of 100 that the estimatewould have been a figure differing from a com-plete census figure by less than 32,000. [hechances are 95 out of 100 that the estimatewould have differed from a complete censusfigure by less than 64,000 (twice the standarderror).
Of these 1,092,000 total female headedfamilieswith income from earnings below the low-incomelevel, 46,000 or 45.4 percent were black femaleheaded families, [able A-9 shows the standarderror of 45.4 percent on a base of 1,092,000to he approximately 1.5 percent. Consequently,chances are 68 out of 100 that the estimated4"-').4 would he within 1.5 percentage points ofa ...omplete census figure, and chances are05 out of 100 that the estimate would be withinDI percentage points of a census figure; i.e.,this 05 percent confidence interval would befrom 42.4 to 48.4 percent.
Illustration of the use of tables of standarderrors for regional estimates. Table 11 ofthis report shows that in 1972 there were3,803,000 persons below the low-income levelin region \. rabic :\ -10 shows the standarderror on an estimate of this size to be approxi-mately 450,000. File chances are 68 out of 100that the estimate would have been a figurediffering from a complete census figure by
less than 450.000. The chances are 95 out of100 that the estimate would have differedfrom a complete census figure by less than900,000 (twice the standard error).
Of these 3,803,000 persons, 987,000 or 26.0percent, were black persons below the low-incomelevel in region V. Table A-11 shows thestandard error of 26.0 percent on a base of3,803,000 to be approximately 3.2. Consequently,chances are 68 out of 100 that the estimated26.0 percent would be within 3.2 percentagepoints of a complete census figure, and chancesare 95 out of 100 that the estimate would bewithin 6.4 percentage points of a census figure;i.e., this 95 percent confidence interval wouldbe from 19.6 to 32.4 percent.
Illustration of the computation of the standaruerror of a difference for national estimates.Table 8 of this report shows that in 1971 therewere 1,058,000 total female headed familieswith income from earnings below low-incomelevel. Thus, the apparent change in the numberof female headed families with income fromearnings below low-income level in 1971 and1972 is 34,000. The standard error of the1972 estimate of 1,092,000 is 32,000, asshown above. Table A-5 shows the stand-ard error on an estimate of 1,058,000to he approximately 32,000. The standarderror of the estimated change of 34,000 isabout 45,000 =/(32,000) 2
+ (32,000)2 Thismeans the chances are 68 out of 100 that theestimated difference based on the sampleswould differ from the change derived usingcomplete census figures by less than 45,000.
The 68 percent confidence interval around the34,000 change is from -11,000 to 79,000, i.e.,34,000 + 45,000. A conclusion that the averageestimate of the change derived from all possible
samples lies within a range computed in thisway would be correct for roughly 68 percentof all possible samples. The 95 percent con-
59
fidence interval from -56,000 to 124,000(34,000+
2 x 45,000), does not exclude negative valuesand hence, we cannot conclude with 95 percentconfidence that the number of female headedfamilies with income from earnings below thelow-income level in 1972 is actually greaterthan in 1971,
