1.Summary
This article explains demographics. Demography studies how the population changes due to birth, death, and aging. The reason for studying demographics is that demographic analysis can explain many sociological phenomena. This demography began in the late 18th century.
Demographic mainstream data relies on large data sets derived from registration statistics. Because population change is constantly changing, data should be analyzed with this in mind.
Among these data, there are ' fecundity' and 'fertility'. An important concept that accompanies this is the replacement level. The replacement level is the number of children a woman must have to replace her existing population. The replacement level is generally based on 2.1 children per woman. A strong predictor of fertility is the level of education of women. In general, the higher the level of education, the lower the fertility rate. This is not because of education to reduce the fertility rate. This is because women learn by educational means the opportunities for parental transfer. On the extension of this, it can be seen that the development level of the country affects the fertility rate.
Another important factor is mortality. Mortality rates vary slightly from country to country. A good country has a high mortality rate because it has a high number of elderly people even though it has good health. On the other hand, a less developed country has a high mortality rate for infants and young children. Education also has an impact on mortality. It is possible to manage their health efficiently and improve the life span.
Demographic changes are models and theories that explain the transition between birth rate and mortality. The beginning of demographic change in society begins when the mortality rate is not proportional to the fertility rate.
The population is increasing over time. It is becoming overpopulation. Excessive population causes problems of resource shortage. Without proper solutions, things will get worse. As a solution to this, scholars argue that ecosystems will control themselves. However, it is criticized as too optimistic to view the prospect.
In addition, humanity will become more diverse through immigration and urbanization. This has caused a variety of changes, such as changing the environment in which the population lives or changing the way of living.

2.What was interesting?
It was interesting that demographics was an indicator to explain social phenomena. Until I read this article, I only considered demography as a study of the number of people. So it seems that I have never seriously considered the importance of statistics as an indicator to explain sociology.
Also, the content of education related to birth rate and mortality rate was interesting. I have not been able to think that education can change the mortality and birth rate, but it was interesting because it seemed to have a new perspective through this article.
Finally, I was quite surprised to read this article about the severity of the overpopulation. I think it is a bit risky that the current overcapacity is very serious and there is no specific countermeasure for it.
3.Discussion point
The film 'Inferno' sees the problem of overpopulation as evil and tries to take away the ability of humanity to solve it. It was a movie that was interesting in reducing the number of people by eliminating the function of childbirth, rather than reducing the number by spreading the plague and killing people like the Black Death. Of course, I do not think this is an appropriate response to overcrowding. However, I am sympathetic to the fact that the overcrowding problem is serious and we must solve it. If so, what can be the appropriate countermeasures to overcome this overpopulation problem?
