What does population mean?

Population refers to the total population of a certain area on the earth, usually refers to the population at a certain point in time.

Population is usually measured by thousands or millions, such as the population of a city, a country or even the whole world. Population is a dynamic number, which changes with time. There are many factors affecting population, including fertility rate, mortality rate, immigration rate and birth rate. These factors interact with each other and affect the increase, decrease and distribution of population.

The government and society need to formulate corresponding policies and measures to balance the relationship between population growth and resources and environment and realize sustainable development.

Demography is an important field of social science, involving population, age structure, gender ratio, ethnic composition and many other aspects.
