Rate of Natural Increase (RNI) or Natural Increase Rate (NIR)The percent by which the population grows or shrinks each year. Found by: (Birth Rate-Death Rate)/10
Demographic EquationTakes into account birth rates, death rates, immigration, and emigration to find population change
Birth Rates(Number of Live Births/Total Population) x 1000
Death Rates(Number of Deaths/Total Population) x 1000
ImmigrationThe number of people who came here
EmigrationThe number of people who left
FecundityThe likeliness and ability of a woman to have children
Total Fertility Rate (TFR)(Number of Children Born/Number of Women Aged 15 to 45)
Dependency Ratio# of People That Can't Work/# of People Who DO Work
Demographic Transition ModelA theory of how populations change over time
Epidemiological Transition ModelA theory of how medical advances increase population over time
