Summary
Demography is the research of human population dynamics. It’s
necessary to explain many various social phenomena. Demography focus on people
population’s changing, so demography focus specific index of changing. The most
important indexes in demography are death and birth. Sometimes, the getting
exact data is so difficult, therefore demographic understand about changing of
population and social structure so exact data and technology should be
provided. Demographic change is the synthesis and idealistic model of the general population change of the
country. It can be showed with mortality and fertility (birth rate) change
graph, so we can saw a population exposure or population change.

Interested
things
Demography is necessary study in society
research because in theory, explaining phenomena should entail fact so
demographic statics to social study. I was interested about environmental
effect phenomena that named urban heat island that is because of urban heat the
island. I was interested that building’s heat effect directly to ground that
can raise temperature of whole island.

Discussion
In this
time, world population is already overstretched. The world population exposure
can produce
many problems. So I think the world population exposure will be resolved
essentially.But in
many movie, this population exposure resolving extremely like mass destruction. Should
we reduce population essentially? The appropriate population can be achieved?
