Summary
Demography is the study of changes in population, scale, distribution and composition, birth, death, migration, and social mobility. 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. Evaluation of demographic trends requires reliable and long-term data, and the way in which a series of data is scaled back and back is of great importance.
Interesting
Increasingly, people living in rural and rural areas are moving to cities. So, the term urbanization arose. Urbanization is the physical growth of urban areas as a result of global change. The United Nations also defines urbanization as a population increase, such as the migration of population from rural to urban. The United Nations predicted that half of the world's population will live in urban areas by the end of 2008. Urbanization is closely linked to the modernisation, industrialization, and social rationalization processes.
Discussion
As I said above, many people are moving to the city. Although the primary industry has remained in the rural areas, the second and third industrialization has brought many people to the cities. Why do so many people move to the city? Tell me what you think. In addition, the world population has increased a lot. Do you think the world is over-populated?
Many people head for the city. I think the reason is to make money. This is because cities have more jobs and opportunities. The population growth around the world is natural and I don't think it's excessive.
