2. How do natality, morality and migration affect population size?

Population Size = (Immigration + Natality) – (Mortality + Emigration)

Explanation:

The change in the size of a population over time is determined by four key factors:

•  Natality:  Increases to population size through reproduction (births)

•  Immigration:  Increases to population size from external populations

•  Mortality:  Decreases to population size as a result of death

•  Emigration:  Decreases to population size due to loss to external populations
