What are 4 factors that demographers consider when determining human population growth rate?

Demographers consider birth rates, death rates, Immigration, and emigration when determining human population growth rates. Birth rates reflect the number of live births per 1,000 people, while death rates indicate the number of deaths per 1,000 individuals. Immigration adds to the population by bringing in people from other areas, whereas emigration represents those leaving the population. Together, these factors help assess the overall trends in population dynamics.
