What is generally meant by population growth?

Answer and explanation

Correct answer: Change in population size over a period

Population growth means the change in the size of a population during a stated period, such as a year or a decade. The total change depends on births and deaths within the population and on migration across the area’s boundary. In simple terms, growth may be positive when additions exceed losses, or negative when losses exceed additions.

Counting births alone gives only one component and ignores deaths and migration. Counting migrants alone also misses natural change. Population density is a measure of people per unit area, not the change in population size. Therefore option A is correct: population growth refers generally to change in population size over a period.
