 (1)Summary:

The concept of demography and its impact on society and the economy, in particular China's population policy. Demography is the study of population dynamics, including the study of population size, structure, and distribution, and how populations change over time due to births, deaths, migration, and aging. Demographic analysis is a powerful tool for explaining social phenomena and can provide valuable insights even when interpreting world events.

Historically, demography has its roots in the social changes brought about by the scientific and industrial revolutions. Early demographers developed some primitive life tables to measure a population's life expectancy, and universal censuses also began to be used for political purposes, such as taxation and political representation.

Demography relies on large data sets from censuses and registration statistics such as birth, death and marriage registrations. These data sets need to be accumulated over long periods of time in order to analyze trends in demographic indicators, such as birth and death rates. However, in many countries, especially in developing countries, reliable population data remains difficult to obtain.

Demography focuses on specific indicators of population change, including birth rates, death rates, and migration trends. In addition, the article also mentions important concepts related to fertility, such as fertility and fertility, and the impact of these concepts on different regions. The paper also introduces the theory of demographic transition, which describes the process of a country's transition from high birth and death rates to low birth and death rates, and the impact of this transition on demographic structure and economic development.

Finally, the paper discusses the problem of population growth and overpopulation. Overpopulation is when the number of a species exceeds the carrying capacity of its niche, not just the number or density of individuals. Global population growth has led to increased demand for resources, which may lead to food shortages, energy shortages, ecological degradation, and war. The article also mentions the impact of some human activities on the environment, and how to solve these problems through reasonable management of agriculture and environmental protection.

Some characteristics of overpopulation and possible solutions. First, the article lists some characteristics of overpopulation. These include child poverty, high birth rates, low life expectancy, low literacy levels, higher unemployment, insufficient arable land, low food stocks, malnutrition and diet deficiency diseases (such as rickets), low GDP per capita, increasingly unsanitary conditions, increased economic pressure on governments, increased crime as people steal resources in order to survive. And the mass extinction of plants and animals caused by human activities.

Secondly, the article mentions that the phenomenon of urbanization is the result of industrialization and population growth, and also mentions some different views on the impact of population growth on living standards, including Virginia Abernethy's view that in countries with strong male rights, high living standards tend to lead to population growth.

Among the possible solutions to overpopulation, some believe that economic development is the best way to reduce population growth, while others believe that providing a combination of help aimed at population control and self-sufficiency is the most effective approach, including measures to improve women's education, economic status and political power.

Finally, issues such as underpopulation, migration and urbanization point to their possible economic and environmental impacts.

(2)Interesting point:

Demographic concepts and data analysis can help us understand every aspect of society, from economic development to urbanization phenomena, and even political and cultural changes.

(3)Q:

How much does population policy affect the functioning of society? Is there an example of this in your country or region?
