Week 14 / Demography / Soongki Kim

1.      Summary
  Demography is the study of population dynamics. It includes research into the size, structure, and distribution of the population, and how the population changes over time due to birth, death, migration, and aging.It is then analyzed by standards such as education, religion, or ethnicity. Before proposing complex theories, sociologists must first switch to demographic indicators for possible explanations. So I study demographics.
Census has been around for a long time, but demographic calculations developed in the 18th century.
Demographics rely primarily on large datasets derived from surveys and registration statistics. Developing trends in demographics, such as birth and death rates, requires a large data set over a long period of time.

2. What was interesting/What did we learn
  The central interest in demographics is to establish reliable metrics that measure the total number of people, birth rate, marriage and death rate. In most history, and in today's world, these measurements are very problematic. The most reliable data—Census, birth, marriage and death—returned until 200 years ago. Even when data exists, there are problems of variation and the record process is designed to be difficult to interpret, especially in economically underdeveloped areas and where bureaucracy is not efficient. We found that the assessment of demographic trends required reliable and long-term data, and that the way in which a series of data was extended back in time was of great importance.

3.Discussion Point
   Demographics are demographics related to socio-economic factors such as age, income, sex, occupation, education, and family size. This study deals with demographic changes, such as the death rate of the population. If there is a change in the number of people in the study that statistics changes in population, it will have an impact on social areas such as economy and policy. Do you agree with these comments? If so, how does the population change affect society?
