The natural growth rate of population can be defined as the difference between the birth rate and the death rate in a given population over a certain period of time, usually a year. It represents the rate at which the population is growing due to the excess of births over deaths. For instance, if the birth rate is 20 per 1,000 people per year and the death rate is 10 per 1,000 people per year, the natural growth rate would be 10 per 1,000 people per year. The natural growth rate can be used to estimate future population trends and plan for future needs such as healthcare, education, housing, and employment.
