1) The best memorable content in Week14: Demography

Demography is the study of human population dynamics. In other words, Demography is a research of the human population, and it studies everything related to it. For example, population structure, distribution, and population change and so on. The scope of demography is extensive. It can be a study of the whole of humanity, or it can be a small group of people or community. So why do scholars study Demography? The reason for this is that 'Demographic analysis' is an index for studying various social phenomena. In other words, research on the human population should be the study, so many social phenomena can be analyzed and understood. For example, there are various reasons such as war, epidemic spread, fashion movement, tax collection.

Demography studies are based on large data sets. These data should be updated periodically, and should be checked from time to time. This continues to change quickly, so if country do not update the data in the past, there is a high probability of errors in the study. Developed countries think importantly and do continuously this update, but sub-nations such as developing countries have difficulty in investigating it properly.

There are two criteria that we consider important when examining this.

First, the birth rate and mortality rate. In other words, population change is the most important factor in demography. Population change is due to birth and death, and the pattern has been changing ever since. For example, in the past, the fertility rate was much higher than the mortality rate, the population was maintained and the young people lived a lot. But now, in some developed and developing countries, birth rates are very low and mortality rates are low too. So the population is growing compared to the past, but there are fewer younger people and more elderly people. In other words, the population is becoming aged. Population aging has a great impact on the entire society. Research on birth and death is very important when studying demography. It is education that has a high impact on mortality. According to recent studies, the more education you receive, the longer you live. For example, a person who receives more education lives longer than others. Because he or she is more careful about harmful activities such as smoking. There are things that affect birth and death. For example, there are wealth, health, and race of the person.

The second is population movement. Historically, humans have moved on continuously. For example, the voyage of Columbus proved that the earth is round, which is one of the most important discoveries in Earth's history. It is also a historical event that people who have traveled on ships in the past discover new nations and discover their culture.

Thus, population change and population dynamics are important to investigate demography. The people continues to repeat births and deaths, and population continues to move and settled.What if the population is more than acceptable? This condition is called 'overpopulation'. There are limited resources and food in the world. But if there are more people than this allowed, there will be a shortage of food and a lack of nature. Their absence will lead to a war to obtain more rare values.

Earth's peace will disappear. Therefore, research on food and environment-friendly resources will be needed constantly.

2)My mention and question in this link.



In this link we learned about Demography. As mentioned above, research on population plays an important role in understanding society. When we think about the phenomenon of society, we must think that the study of population or people should be the basis. The population continues to repeat births and deaths, and I am a person living in that age. As the aging of the population and the shortage of resources are serious, research to resolve them is absolutely necessary. So what is the way to raise the fertility rate and secure a younger generation?
