1. summary
Demography is the study of human population dynamics.
The history of demography begins with the life tables of early mathematicians.
Censuses, another demographic tool, were institued for primarily political purposes: as a basis for taxation, as a basis for political representation.
Demography's two of the most important indicators are birth and death rates.
Fertility and Fecundity, Mortality is the ways to explore the elements of population change.
It also says Population Growth and overpopulation.
Overpopulation indicates a scenario in which the population of a living species exceeds the carrying capacity of its ecological niche. It is not simply a population-rich state, but a comparison of population and available resources.
2. intersting things

This explains the difference in population growth between pre-industrial and post-industrial societies.
As with all models, this is an idealized, composite picture of population change in these countries. The model is a generalization that applies to these countries as a group and may not accurately describe all individual cases.
3. discussion point

It is because there are too many people compared to resources.
Lack of resources causes conflict.
There are too many conflicts with resources in the world.
Economic and diplomatic conflicts sometimes lead to war.
