1. Summary
Demographics are the study of population size, structure, distribution, and changes in population that analyze births, deaths, migration, and aging. It is an important tool to explain social phenomena, evaluating the impact of population growth on historical events, along with political and economic factors. The discipline developed during the scientific and industrial revolutions, and was initially used for life insurance and political purposes. It mainly utilizes data from censuses, births, deaths, and marriage registration, and fertility and mortality are the main indicators. Fertility rates are closely related to women's educational levels and economic opportunities, and mortality rates are affected by hygiene and medical advances. The demographic transition accounts for the transition from high birth rates and mortality to low birth rates and mortality rates, which are mainly attributed to improved sanitation and medical advances. Population growth and excess occur mainly in underdeveloped countries, where the population increases due to immigration. Social and economic factors should also be considered important in discussing food supply and population relations.
2. What did I learn
With demographics, we can gain a deep understanding of the impact of demographic changes on society and the economy. We can learn how birth rates and mortality rates are related to education, economic opportunities, hygiene, and healthcare development, and find that demographic transitions are closely linked to social development. In addition, it can be understood that population growth and excess problems occur mainly in developing countries, and in developed countries, immigration is an important factor in population growth. Finally, we can learn that social and economic factors, as well as numbers, should be considered when discussing population and resource issues.
3. discussion
Given the current pace of global population growth, what policies should developing and developed countries prioritize for sustainable development?
Developing countries should focus on education and improving women's rights, health and family planning, economic development, and urban infrastructure development. Developed countries should prioritize policies to prepare for an aging society, immigration policies, sustainable development, and encourage childbirth. It is important that all countries cooperate in environmental protection and sustainable development.
