Question: Name the four factors that affect population growth. then, explain how each factor contributes to population growth.

The four factors that affect population growth are birth rate, death rate, immigration, and emigration. Each of these factors contributes to the change in the size and composition of a population over time.

Birth rate is the number of births per 1000 individuals in a population per year. It is influenced by factors such as fertility, age structure, family planning, education, culture, and health care. A high birth rate increases the population size and the proportion of young individuals.

Death rate is the number of deaths per 1000 individuals in a population per year. It is influenced by factors such as life expectancy, disease, nutrition, sanitation, war, and natural disasters. A low death rate decreases the population size and increases the proportion of old individuals.

Immigration is the movement of individuals into a population from another region or country. It is influenced by factors such as economic opportunities, political stability, social networks, and environmental quality. Immigration increases the population size and may change the genetic and cultural diversity of a population.

Emigration is the movement of individuals out of a population to another region or country. It is influenced by factors such as poverty, unemployment, conflict, persecution, and climate change. Emigration decreases the population size and may reduce the genetic and cultural diversity of a population.
