What does population growth actually mean?

Answer and explanation

Correct answer: Change in population number during a fixed period

Correct answer: A. Population growth means the change in the number of people living in a place over a specified period. The change may be an increase or, in some contexts, a decrease. It can result from births and deaths, and it can also be affected by migration. To measure it properly, we need a starting population, an ending population and a time interval. A is correct because it gives both essential ideas: population number and time. B describes a change in area, not people. C describes literacy change, which is a social indicator but not population growth itself. D concerns administrative boundaries; changing a boundary can alter the counted population without representing natural growth. Memory cue: population growth always asks, “How did the number of people change over time?”
