summary
1. #Demography
This week's topic is demography.
Demography is the study of human population.
Demographics is also a study of changes in population, birth, death, and migration.
There is something important in demographic.
It is to establish a reliable measure of total population, birth rate, and death rate.
It is difficult to obtain reliable demographic in many countries.
This is especially difficult in developing countries.

The demographic changes are affected by the nation's economy.
It is a theory that explains the changes in mortality and birth rate.
In the pre-industrial age, population growth rate is relatively low because both birth rate and mortality rate are high.
In most post-industrial societies, both birth rates and mortality are low.
3. #Population Growth and Overpopulation
Overpopulation is a rapid increase in population and thus exceeds the population limit of the area.
Overpopulation is not a function of individuals.
They compare the number of resources they need to survive.
Presently, every year the world's human population grows by approximately 80 million.
Most of the world population growth occurs in developing countries.
Some of the characteristics of overpopulation are as follows.
First, it has a high fertility rate and a low average life expectancy.
Second, the lack of arable land and the resulting surplus food.
Third, crime rates increase as people steal resources to survive.
There is such a problem.
my opinion
Demography is an interesting subject for me.
Problems and characteristics of population growth were interesting.
It also found that the world is undergoing a population growth.
Our country has a problem with the lack of population.
I think other countries have different population problems.
For example, there are aging problems and urbanization problems.
Therefore, I think that it should establish measures to solve these problems for each country.
I read your post well. Your article is a good summary of this link and it was good to read. I like this theme interestingly too. As I studied this link, I realized that it is important to study the population when studying society!
ReplyDeleteI think so. Is there effect way to solve problem of low population? What is your opinion about way to solve this problem?
