What shows the speed of population growth?

Answer and explanation

Correct answer: Population growth rate

The direct answer is A: the population growth rate shows how quickly population changes. A rate expresses change in relation to time, often over a specified period. Population growth depends on births, deaths, and migration; the growth rate summarizes the resulting increase or decrease. Option A is correct because it directly answers the question about speed. Option B is only the number of births in relation to population and does not include deaths or migration, so it alone cannot show the final growth speed. Option C measures deaths and is one factor affecting change, but it does not describe total growth by itself. Option D tells how many people live per unit of area; it describes concentration, not the speed of change. Memory cue: growth rate answers “how fast,” while density answers “how crowded.”
