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 = 21/1000
Then convert to 100
Growth 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? 1.9
What 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?
Try being a demographer!
