1. summary
Demography is a study of the changes in population, size, distribution and composition, birth, death, migration, and social mobility.Demography depends heavily on human birth and death figures.
First, let's look at the fertility rate. The fertility rate of each country is different. The most influential factor in the fertility rate of women is the level of education of women. The higher the level of education, the lower the fertility rate.
The next thing to look at is mortality.In advanced countries, infant mortality rate is lower. In developed countries, life expectancy is higher. In addition to these numerical results, this article describes various concepts.
Demographic transition implies that mortality rates are not kept at the same rate but mortality rates are lower than birth rates.
Overpopulation refers to a sudden increase in population, which exceeds the local population limit.
If all of the earth's produce is distributed equally, a large population will be able to eat, It is not by capitalism. Therefore, overpopulation leads to famine, child poverty, increased crime for survival.
The solution to this overpopulation is a natural solution (death due to hunger problems) or economic development.
Another concept is urbanization. Urbanization refers to the process of concentration of population into urban areas, which is a change in urban lifestyles. Urbanization occurs because it can not improve the level of life in the countryside. This also happens because there are more benefits and services in the city. However, this urbanization is accompanied by a heat island effect.
2. intersting things
It was interesting that the fertility rate was related to the education level of women.
There will be a number of factors here.
So I want to study these factors.
3. discussion point
Urbanization reduces the number of young rural residents.
If this happens, there will be no people left in the countryside.
What is the solution to this situation?
