CONSUMER PRICE INDEX: JANUARY 2007 The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.3 percent in January, before
seasonal adjustment, the Bureau of Labor Statistics of the U.S. Department of Labor reported today. The January level of 202.416 (1982-84=100) was 2.1 percent higher than in January 2006.
The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) increased 0.2 percent in January, prior to seasonal adjustment. The January level of 197.559 (1982-84=100) was 1.8 percent higher than in January 2006.
The Chained Consumer Price Index for All Urban Consumers (C-CPI-U) increased 0.3 percent in January on a not seasonally adjusted basis. The January level of 117.417 (December 1999=100) was 1.9 percent higher than in January 2006. Please note that the indexes for the post-2005 period are subject to revision. Previously published and revised data for 2005 and 2006 are shown on page 5. CPI for All Urban Consumers (CPI-U)

of 0.4 percent in December. Energy costs, which increased 4.2 percent in December, declined 1.5 percent in January. Within energy, the index for petroleum-based energy fell 3.1 percent, while the index for energy services rose 0.5 percent. The food index rose 0.7 percent in January, its largest advance since a 0.8 percent increase in April 2005. The index for all items less food and energy advanced 0.3 percent in January, following a 0.1 percent rise in December; an increase in the index for medical care accounted for about 60 percent of the acceleration.
The food and beverages index rose 0.7 percent in January. The index for food at home increased 0.9 percent,
following a 0.3 percent decrease in December. The index for fruits and vegetables, which declined 1.7 percent in December, increased 1.3 percent in January. The indexes for fresh fruits and for fresh vegetables increased 1.5 and 1.9 percent, respectively, while the index for processed fruits and vegetables decreased 0.3 percent. The indexes for nonalcoholic beverages and for other food at home, each of which declined 0.2 percent in December, increased 0.8 and 0.9 percent, respectively, in January. The index for dairy products advanced 1.3 percent in January, following a 0.1 percent rise in December, reflecting large price increases for milk, cheese and ice cream. The index for meats, poultry, fish, and eggs, which also increased 0.1 percent in December, advanced 0.8 percent in January, reflecting increases in the indexes for other meats and for fish and seafood--up 2.7 and 1.4 percent, respectively. The indexes for beef and for pork each increased 0.3 percent, while poultry prices fell 0.4 percent. The index for cereal and bakery products increased 0.3 percent in January, the same as in December. The other two components of the food and beverages index--food away from home and alcoholic beverages--increased 0.5 and 0.9 percent, respectively.
The index for housing rose 0.2 percent in January, following a 0.4 percent increase in December. The index
for fuels and utilities, which increased 1.2 percent in December, rose 0.3 percent in January. The index for fuel oil declined 5.6 percent in January, following a 2.8 percent increase in December. The index for natural gas, which had increased sharply in November and December, declined 3.0 percent in January. These declines were more than offset by increases in the indexes for electricity and for water, sewer and trash collection--up 2.0 and 1.0 percent, respectively. The index for shelter increased 0.3 percent in January, the same as in December. Within shelter, the index for rent rose 0.4 percent; owners' equivalent rent increased 0.2 percent; and the index for lodging away from home rose 1.1 percent. (Prior to seasonal adjustment, the index for lodging away from home increased 4.6 percent.) The index for household furnishings and operations, which rose 0.1 percent in December, declined 0.3 percent in January.
The transportation index declined 0.8 percent in January. The index for gasoline prices, which rose 6.9
percent in December, declined 3.0 percent in January. Gasoline prices, which rose sharply in the first part of 2006, before declining throughout most of the second part of the year, were 2.7 percent lower than a year ago and 32.0 percent lower than their peak level recorded in July 2006. The index for new vehicles was virtually unchanged in January, following declines in each of the preceding three months. (As of January, about 82 percent of the new vehicle sample was represented by 2007 models. The 2007 models will continue to be phased in, with appropriate adjustments for quality change, over the next several months as they replace old models at dealerships.) The index for used cars and trucks decreased 0.7 percent in January. The index for public transportation rose 1.5 percent in January, reflecting a 2.1 percent increase in the index for airline fares.
The index for apparel rose 0.3 percent in January, following a 0.2 percent increase in December. (Prior to
seasonal adjustment, apparel prices fell 2.2 percent, reflecting post-holiday discounting.) Medical care costs rose 0.8 percent in January and are 4.3 percent higher than a year ago. The index for
medical care commodities--prescription drugs, nonprescription drugs, and medical supplies--increased 0.6 percent. The index for medical care services advanced 0.9 percent. The indexes for professional services and for hospital and related services increased 0.8 and 0.6 percent, respectively.
The index for recreation increased 0.1 percent in January. Increases in the indexes for pets, pet products and
services, for club membership dues and fees for participant sports, and for admissions to movies, theaters, concerts, and sporting events more than offset declines in the indexes for video and audio, for sporting goods, for photography, and for toys.
The index for education and communication declined 0.1 percent in January. Educational costs increased
0.1 percent, reflecting a 1.7 percent increase in the index for college textbooks. Communication costs decreased 0.4 percent. Within the communication group, the index for information and information processing declined 0.4 percent as a 0.1 percent increase in telephone services was more than offset by declines in the indexes for personal computers and peripheral equipment, for computer software and accessories and for internet services and electronic information providers. The last mentioned component has declined in each of the last seven months and is 22.1 percent lower than in January 2006.
The index for other goods and services increased 0.8 percent in January. The index for tobacco and smoking
products, which rose 1.5 percent in December, increased 3.1 percent in January and accounted for four-fifths of the January advance in this major group.

Consumer Price Index data for February are scheduled for release on Friday, March 16, 2007, at 8:30 A.M. (EDT).
Consumer Price Index Levels to Three Decimal Places Effective with this release of the Consumer Price Index (CPI), the Bureau of Labor Statistics has begun
computing percent changes based upon three decimal place indexes rather than one decimal place indexes. This change applies to the All Items Consumer Price Index and all component indexes for the CPI-U, CPI-W, and C-CPI-U, for the U.S. City Average and for all other published areas. In addition, CPI index values are displayed to three decimal places in all paper and electronic publications. As in the past, percent changes are rounded to one decimal place.
This change in procedure addresses a rounding issue that has resulted in published percent changes
that are 0.1 percentage point higher or lower than the same percent changes based on unrounded index values (i.e., indexes to three or more decimal places). These differences can be particularly important when percent changes are very small. Publishing the index values to three decimal places, and using these values to compute percent changes, essentially eliminates the rounding differences. This change only affects the presentation of the index data. Index values continue to be calculated from underlying price data in the same manner as in the past, and no systematic upward or downward effect on the data is introduced. The levels of future indexes will be affected only in that they will be published to three decimal places rather than one. Official CPI data previously published will not be revised.

Note on Sampling Error in the Consumer Price Index
The CPI is a statistical estimate that is subject to sampling error because it is based upon a sample of
retail prices and not the complete universe of all prices. BLS calculates and publishes estimates of the 1-month, 2-month, 6-month and 12-month percent change standard errors annually, for the CPI-U. These standard error estimates can be used to construct confidence intervals for hypothesis testing. For example, the estimated standard error of the 1 month percent change is 0.06 percent for the U.S. All Items Consumer Price Index. This means that if we repeatedly sample from the universe of all retail prices using the same methodology, and estimate a percentage change for each sample, then 95% of these estimates would be within 0.12 percent of the 1 month percentage change based on all retail prices. For a 1-month change of 0.2 percent in the All Items CPI for All Urban Consumers, we are 95 percent confident that the actual percent change based on all retail prices would fall between 0.08 and 0.32 percent. For the latest data, including information on how to use the estimates of standard error, see “Variance Estimates for Changes in the Consumer Price Index, January 2005- December 2005 in the CPI Detailed Report, February 2006. These data are available on the CPI home page (http://www.bls.gov/cpi), using the following link http://www.bls.gov/cpi/cpivar2006.pdf C-CPI-U Index Revisions
In accordance with the previously-announced schedule, the Bureau of Labor Statistics is revising the 2005 and 2006 values of the Chained Consumer Price Index for All Urban Consumers (C-CPI-U), effective with the release of January 2007 data.
The C-CPI-U was introduced with release of July data on August 16, 2002. The index in its final form employs a Tornqvist formula and utilizes expenditure data in adjacent time periods in order to reflect the effect of any substitution that consumers make across item categories in response to changes in relative prices. The C-CPI-U was designed to be a closer approximation to a “cost-of-living” index than the CPI-U and CPI-
W. The use of expenditure data for both a base period and a current period distinguishes the C-CPI-U from the other CPI measures, which use only a single expenditure base period to compute price change over time.
Because the current expenditure data required for the calculation of the C-CPI-U are available only with a time lag, the index is issued first in preliminary form, using the latest available expenditure data at the time of publication, and is subject to two subsequent revisions. The preliminary values for each month of the preceding two years are revised annually with release of the January index. Expenditure data for the year 2005 are now available, and the C-CPI-U indexes for that year are now in final form. The initial indexes for 2006 are now revised interim indexes. The C-CPI-U U.S. All Items index values for 2005 and 2006 as originally published and revised are shown below.

The Consumer Price Index (CPI) is a measure of the average change in prices over time of goods and
services purchased by households. The Bureau of Labor Statistics publishes CPIs for two population groups: (1) the CPI for Urban Wage Earners and Clerical Workers (CPI-W), which covers households of wage earners and clerical workers that comprise approximately 32 percent of the total population and (2) the CPI for All Urban Consumers (CPI-U) and the Chained CPI for All Urban Consumers (C-CPI-U), which cover approximately 87 percent of the total population and include in addition to wage earners and clerical worker households, groups such as professional, managerial, and technical workers, the self-employed, short-term workers, the unemployed, and retirees and others not in the labor force.
The CPIs are based on prices of food, clothing, shelter, and fuels, transportation fares, charges for
doctors’ and dentists’ services, drugs, and other goods and services that people buy for day-to-day living. Prices are collected in 87 urban areas across the country from about 50,000 housing units and approximately 23,000 retail establishments-department stores, supermarkets, hospitals, filling stations, and other types of stores and service establishments. All taxes directly associated with the purchase and use of items are included in the index. Prices of fuels and a few other items are obtained every month in all 87 locations. Prices of most other commodities and services are collected every month in the three largest geographic areas and every other month in other areas. Prices of most goods and services are obtained by personal visits or telephone calls of the Bureau’s trained representatives.
In calculating the index, price changes for the various items in each location are averaged together
with weights, which represent their importance in the spending of the appropriate population group. Local data are then combined to obtain a U.S. city average. For the CPI-U and CPI-W separate indexes are also published by size of city, by region of the country, for cross-classifications of regions and population-size classes, and for 27 local areas. Area indexes do not measure differences in the level of prices among cities; they only measure the average change in prices for each area since the base period. For the C-CPI-U data are issued only at the national level. It is important to note that the CPI-U and CPI-W are considered final when released, but the C-CPI-U is issued in preliminary form and subject to two annual revisions.
The index measures price change from a designed reference date. For the CPI-U and the CPI-W the
reference base is 1982-84 equals 100.0. The reference base for the C-CPI-U is December 1999 equals 100. An increase of 16.5 percent from the reference base, for example, is shown as 116.5. This change can also be expressed in dollars as follows: the price of a base period market basket of goods and services in the CPI has risen from $10 in 1982-84 to $11.65.

Information and Analysis Section on (202) 691-7000.
Calculating Index Changes
Movements of the indexes from one month to another are usually expressed as percent changes rather than changes in index points, because index point changes are affected by the level of the index in relation to its base period while percent changes are not. The example below illustrates the computation of index point and percent changes.
Percent changes for 3-month and 6-month periods are expressed as annual rates and are computed
according to the standard formula for compound growth rates. These data indicate what the percent change would be if the current rate were maintained for a 12-month period. Index Point Change CPI 202.416 Less previous index 201.800 Equals index point change .616 Percent Change Index point difference .616 Divided by the previous index 201.800 Equals 0.003 Results multiplied by one hundred 0.003x100 Equals percent change 0.3
Regions Defined The states in the four regions shown in Tables 3 and 6 are listed below. The Northeast--Connecticut, Maine, Massachusetts, New Hampshire, New York, New Jersey, Pennsylvania, Rhode Island, and Vermont. The Midwest--Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. The South--Alabama, Arkansas, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, West Virginia, and the District of Columbia. The West--Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.
A Note on Seasonally Adjusted and Unadjusted Data
Because price data are used for different purposes by different groups, the Bureau of Labor Statistics publishes seasonally adjusted as well as unadjusted changes each month.
For analyzing general price trends in the economy, seasonally adjusted changes are usually preferred
since they eliminate the effect of changes that normally occur at the same time and in about the same magnitude every year--such as price movements resulting from changing climatic conditions, production cycles, model changeovers, holidays, and sales.
The unadjusted data are of primary interest to consumers concerned about the prices they actually pay.
Unadjusted data also are used extensively for escalation purposes. Many collective bargaining contract agreements and pension plans, for example, tie compensation changes to the Consumer Price Index unadjusted for seasonal variation.
Seasonal factors used in computing the seasonally adjusted indexes are derived by the X-12-ARIMA
Seasonal Adjustment Method. Seasonally adjusted indexes and seasonal factors are computed annually. Each year, the last 5 years of seasonally adjusted data are revised. Data from January 2002 through December 2006 were replaced in January 2007. Exceptions to the usual revision schedule were: the updated seasonal data at the end of 1977 replaced data from 1967 through 1977; and, in January 2002, dependently seasonally adjusted series were revised for January 1987-December 2001 as a result of a change in the aggregation weights for dependently adjusted series. For further information, please see “Aggregation of Dependently Adjusted Seasonally Adjusted Series,” in the October 2001 issue of the CPI Detailed Report.
The seasonal movement of All items and 54 other aggregations is derived by combining the seasonal
movement of 73 selected components. Each year the seasonal status of every series is reevaluated based upon certain statistical criteria. If any of the 73 components change their seasonal adjustment status from seasonally adjusted to not seasonally adjusted, not seasonally adjusted data will be used in the aggregation of the dependent series for the last 5 years, but the seasonally adjusted indexes will be used before that period. Note: 44 of the 73 components are seasonally adjusted for 2007.
Seasonally adjusted data, including the All items index levels, are subject to revision for up to five
years after their original release. For this reason, BLS advises against the use of these data in escalation agreements.
Effective with the calculation of the seasonal factors for 1990, the Bureau of Labor Statistics has used
an enhanced seasonal adjustment procedure called Intervention Analysis Seasonal Adjustment for some CPI series. Intervention Analysis Seasonal Adjustment allows for better estimates of seasonally adjusted data. Extreme values and/or sharp movements which might distort the seasonal pattern are estimated and removed from the data prior to calculation of seasonal factors. Beginning with the calculation of seasonal factors for 1996, X-12-ARIMA software was used for Intervention Analysis Seasonal Adjustment.
In January 2007, BLS adjusted 37 series using Intervention Analysis Seasonal Adjustment, including
selected food and beverage items, fuel oil, motor fuels, vehicles, jewelry, admission to sporting events and educational books and supplies. For example, this procedure was used for the Motor fuel series to offset the effects of damage to oil refineries from Hurricane Katrina, as well as the effects of implementing new fuel requirements in the United States.

NOTE: Local area indexes are byproducts of the national CPI program. Each local index has a smaller sample size than the national index and is,therefore, subject to substantially more sampling and other measurementerror. As a result, local area indexes show greater volatility than the nationalindex, although their long-term trends are similar. Therefore, the Bureau ofLabor Statistics strongly urges users to consider adopting the nationalaverage CPI for use in their escalator clauses.
