Births, Deaths, and Migration. Population growth rate depends on birth rates and death rates, as well as migration.
What 3 demographic characteristics are used to describe populations?
Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006).

Demographic—or more broadly, sociodemographic—statistics refer to characteristics of a population, such as age, race, ethnicity, gender, sexual orientation, income, education, and marital status.
What are the 4 factors that affect population size?
When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.
