A city’s population in the 1987 was 125,524. In 2007 the population was 436,884. Determine the population rate of increase or decrease
Find the population change:
Population Change = New Population - Old Population
Population Change = 436,884 - 125,524
Population Change = 311,360
Since the population change increased, we calculate the rate of increase:
Rate of increase = 100% * Population Change / Starting Population
Rate of increase = 100% * 311,360 / 125,524
Rate of increase = 100% * 2.48
Rate of increase = 248%
