(per 1000 People)
Brazil 14.7 6.1
Cambodia 24.1 6.1
Italy 8.3 9.8
Mali 43.5 10.5
Venezuela 19.6 5.5

A. The immigration and emigration rates of the countries are insignificantly small or approximately equal.
B. The immigration rates of the countries are much higher than the emigration rates.

In order to use only the birth and death rates to calculate the rate of population growth or decrease of a country, the immigration and the emigration rates must either be insignificant or approximately equal.

Population growth rate

The growth rate of a population is determined by the following equation:

Growth rate = (Birth rate - death rate) + (Immigration - Emigration)

Thus, if immigration is more or less equal to emigration or both factors are insignificantly small, the difference between the birth and death rates can be used to estimate the population growth.
