Summary
When a person explains a global event,
demography is useful.
Demography depends on large data sets. Developing
countries are hard to get demographic data.
Because demography is sensitive to
population numbers, demographers focus on specific indicators of population
change.
In demography, fertility is also important. A strong predictor of
fertility is the level of education of women.
In general, the lower the
education level of women, the higher the fertility rate. Also, demography is
interested in mortality.
This article shows the population change due to food
availability. This article also shows the problem of overpopulation.
This article shows the explanation of
urbanization and the economic and environmental effects of urbanization.
Mention & Question

I am interested in population issues.
Today, most developed countries have serious population problems.
It is a
lowbrith and aging problem. This problem causes many problems.
Looking at the
graph of this problem, young people will continue to decline. And the old
people will continue to increase, and later they will suffer a serious shortage
of hands.
We must strive to solve this problem.
What do you think about this
problem? What is the solution to this problem?
