  • Factors affecting the growth & size of human populations
    • Ultimately the balance between birth rates and death rates
    • Immigration - where individuals join a population from outside
    • Emigration - Where individuals leave a population
    • Population growth = (births + immigration) - (deaths + emigration)
    • Percentage population growth rate = population change during that period / population at the start of that period x 100
