The formula for the rate of natural increase is: (

**Crude**birth rate −**Crude**death rate) / 10, where birth and death rates are in per thousand. The**result**is the rate of natural increase in percentage form.Keeping this in view, how do you calculate natural increase?

Rate of change. Births and deaths are

**natural**causes of population change. The difference between the birth rate and the death rate of a country or place is called the**natural increase**. The**natural increase**is calculated by subtracting the death rate from the birth rate.What country has the highest rate of natural increase?

How do you figure out the NIR?

**Formula**for finding the Natural Increase Rate (

**NIR**) Find the Crude Birth Rate (CBR) for each country in your region and add them… Find the Crude Death Rate (CDR) for each country in your region and add them… A country has a CBR of 21/1,000 and a CDR of 10/1,000.
