Total Population Growth is calculated by considering the changes in population due to both natural increase and net migration. The correct approach involves taking the current population and adjusting it by adding the number of births and subtracting the number of deaths to account for natural increase, as well as adding the number of immigrants and subtracting the number of emigrants to account for net migration. This comprehensive formula accurately reflects the dynamics affecting population size.

In this formula, the inclusion of births and deaths captures the natural growth or decline of the population, while the immigration and emigration figures account for those moving into and out of the population. This dual consideration provides a complete picture of why a population may be increasing or decreasing over a specific time period.

This holistic view is why this method of calculation is the most widely accepted approach for determining total population growth.
