Several factors can influence natural increase and population change. Here are some of the key factors:
Birth rate: The number of births per 1,000 individuals in a population. Higher birth rates contribute to natural increase and population growth.
Death rate: The number of deaths per 1,000 individuals in a population. Lower death rates lead to natural increase and population growth.
Fertility rates: The average number of children born to a woman during her reproductive years. Higher fertility rates contribute to population growth, while lower fertility rates can result in population decline or slower growth.
Life expectancy: The average number of years a person is expected to live. Higher life expectancy can result in population growth as people live longer.pearce
