A natural increase is achieved when there is a higher birth rate than death rate. An example of this calculation would be as follows: [(1,600,550 births − 900,234 deaths) ÷ 32,504,906 total number of people in the population] = 0.0215 = 2.15% RNI. Age-Sex and Population Pyramids.

In demography, the rate of natural increase (RNI) is a statistic calculated by subtracting the crude death rate from the crude birth rate of a given region. A significant portion of that population was underfed and starvation remained and remains a significant world problem, but the starvation rate never approached the drastic 96 percent starvation rate Malthus proposed. "Natural increase" is a term used in economics, geography, sociology and population studies.
