Three major factors that affect demography are:
1. Fertility Rate: The average number of children born to a woman in her lifetime influences population growth. Higher fertility rates lead to population expansion, while lower rates cause a decline.
2. Mortality Rate: The frequency of deaths in a population affects demographic changes. Lower mortality rates, often due to improved healthcare, contribute to population growth.
3. Migration: The movement of people between regions or countries impacts the demographic composition. Immigration can increase a population, while emigration reduces it.
