What is meant by population growth?

Answer and explanation

Correct answer: Change in population size over a period

Population growth means the change in the total number of people in a population during a specified period. It can be positive when the number rises, negative when it falls, or almost zero when increases and decreases balance each other. Births and deaths are important components, and migration may also affect the total, so growth is not the same as births alone.

The comparison must be made between population totals at two points in time or over a stated interval. Density is a different measure because it relates population to area. Therefore option A is correct. Options B and C describe only single demographic events, while option D describes spatial concentration rather than change in population size.
