The population growth rate is a rate of change in any population over a given period of time. It is calculated by taking the change in the population (i.e. number of people at the end of the time period minus the number of people at the beginning of the time period) and dividing it by the number of people at the beginning of the time period. This results in a fractional number which can be multiplied by 100 to yield the percentage.
