Remittance - money sent back home by workers
Population pyramids - graphic representation of popualtion dynamics. They divide the
population into 5 year COHORTS by sex. Ie: 0-4, 5-9, 10-14 etc. It is a graph as a percentage of
the total or as absolute numbers. The shape provides important information from a visual
perspective. The pyramid always shows the youngest ages at the bottom and the oldes ages at the
top.
By taking a look at Africa, we can see that impact of AIDS has greatly affected the population of
the country. We can see that this disease is directly impacting women more than men. The
population projected in 2025 would be much larger if AIDS were not in question
IN the middle east, Qatar and Saudi Arabia have a much larger population of middle aged men
that women. This is due to migrant workers coming into the countries for work.
Population pyramids for specific countries show that Brazil is expanding, Canada is stable, and
Germany is contracting. Brazil has a large numbers of children because they are high fertility
rates.
● This shows a wide base of the pyramid.
● However Brazil does have many poor people in the country.
● They do not have much of a middle class at all.
Canada's population pyramid shows a higher life expectancy than Brazil because there are more
old people living.
The baby boom generation is easy to pick out because there was such an increase in population
when they came along
West Germany's population Pyramid 1979
● The people of shortest cohort (ages 60-64) are affected by both World War 1 (low fertility
rate) and World War 2 (fought in the war)
● The cohort of the ages 40-44 is the longest. These are the people who were born between
1935 and 1939. This was the last year before WWII broke out and the economy was good
so there was a baby boom. Also, the Nazi Germans encouraged high fertility for their
expansion toward East Europe. The Nazi Germans believed that good German Women
were to give birth to many German babies. German mohters with many children wer given
mteals to award their dutifulness
● The cohorts before the 40-44 age group are smaller because those people were born during
(low fertility rate due to most men were at war) or after WWII (After which the economy
was bad so there was no baby boom (in Germany it was delayed for 1 decade such as there
was in the U.S. and Canada.)
● There is another bulge in the teenage groups because it was when the economy has gotten
better. This is also result of the "echo effect", when one point in history continue to have
effects on upcoming times
