Answered by Examlex AI CopilotPopulation growth is influenced by a variety of factors, including birth rates, death rates, immigration, and emigration.
High birth rates contribute to population growth, as more individuals are being added to the population than are leaving it. Factors that can influence birth rates include cultural and religious beliefs, access to contraception, and government policies.
Low death rates also contribute to population growth, as individuals are living longer and therefore adding to the overall population. Factors that can influence death rates include access to healthcare, sanitation, and nutrition.
Immigration, or the movement of people into a country, can also contribute to population growth. This is because individuals are being added to the population from outside the country's borders.
Emigration, or the movement of people out of a country, can have the opposite effect on population growth, as individuals are leaving the population.
Overall, population growth is influenced by a complex interplay of these factors, and can have significant impacts on a country's economy, environment, and social structure.
