What's the difference between a net increase in population and an increase in population?

1, the population increase indicates the birth population, and the net population increase indicates the birth population minus the death population. If death is greater than life, it is negative growth. The net population growth rate is the birth rate minus the death rate, also known as the natural growth rate.

2. Calculation formula of net increase population: net increase population = number of births+number of immigrants-number of deaths-number of emigrants.
