Population Formulas in AP Environmental Science

Population Density: Calculated as total population divided by total area, representing how many individuals reside in a specific unit of space.
Birth Rate (%): The percentage of the population that is born over a specific period, determined by the formula (total births/total population) x 100.
Birth Rate per 1000: A standardized way to express birth rate, derived from dividing the birth rate percentage by 100, allowing for easier comparison among different populations.
Death Rate (%): Reflects the percentage of the population that has died within a certain timeframe, calculated using (total deaths/total population) x 100.
Death Rate per 1000: Similar to the birth rate per 1000, this metric is derived by dividing the death rate percentage by 100, facilitating effective demographic analysis.
Crude Birth Rate: Indicates the total number of live births in a population scaled to 1,000 individuals, calculated as (total births/total population) x 1000.
Crude Death Rate: The number of deaths scaled to 1,000 individuals in a population, determined by (total deaths/total population) x 1000.
Population Change: Represents the overall change in a population, factoring in births, deaths, immigration, and emigration, calculated by (births-deaths+immigration-emigration)/population.
Population Growth Rate: Shows how rapidly a population is growing, expressed as a percentage by [(births-deaths+immigration-emigration)/population] x 100 or alternatively (crude births - crude deaths)/10.
Doubling Time: A measure of how long it will take for a population to double in size, calculated using the formula 70/% growth rate.
Percent Change: Reflects the relative change in population size, calculated by [(new-old)/old] x 100.
Natural Rate of Increase: Represents the growth of a population based solely on births and deaths, calculated by subtracting total deaths from total births.
