Demographics the study of human population growth and change

Compare Canada and Cuba -

Which one has more babies born each year?

Which one is probably growing faster?

How can we account for these differences?

We need to be able to compare countries of different geographic sizes

Birth rate Death rate

– # out of 1000 allows us to compare countries of different geographical sizes

Population Growth rate

“Natural Rate of increase” Population growth rate calculated % change = (birth rate + immigrations) – (death rate + emigration)

(everybody IN) minus (everybody OUT)

Try it with your data!Bolivia: BR: 29 DR: 8% change = 29/1000 – 8/1000 = 21/1000Then convert to 100Growth rate?2.1%World GR = 1.2%

Total Fertility Rate (TFR)

Total Fertility rate (TFR) = average # of children a woman will have over her lifetime

TFR in US 1950’s was 3.7 by 1972 less than 2.1 by 2000 officially 2.0

Today? 1.9What was behind this change? How does that relate to the India/Japan video?World: 2.4

Replacement level fertility

Ave # kids needed per woman to replace population

Higher in less developed countries 2.1 is common in more developed countries Why?

Three measures of population health

Infant mortality rate: # of infants out of 1000 that die before age 1

Life expectancy (joint or male/female) GDP or GNI PPP (Gross National Income in

Purchasing Power Parity) per capita

Check for understanding

Consider the video on India/Japan How could knowing “population with access

to improved water sources” and “population with adequate sanitation” help you predict growth rate?

Why is it that MORE infant death actually indicates HIGHER growth rate?
