Answer 1

Births and deaths are natural causes of population change. Thedifference between the birth rateand the death rate of a country or place is called the natural increase. ... For example, if thebirth rate is 14 per 1,000 population, and the death rate is 8 per 1000 population, then the natural increase = 14 - 8 = 6.

Answer 2

The rate of natural increase is the difference between birth and death rates. It measures the degree to which a population is growing. Since birth and death rates are measured as the number of births (or deaths) occurring per 1,000 population, the difference is divided by 10 to convert this rate into a percentage.
