Answer:
To calculate the RNI, demographers subtract the death rate (number of deaths per 1,000 people/year) from the birth rate (number of birth per 1,000 people/year) and convert the answer to a percentage.
Equation for Rate of Natural Increase (RNI):
(BirthRate/1,000) – (DeathRate/1000) = (BR-DR)/1000 = RNI %
Hope it helps!
