What does the population growth rate indicate?

Answer and explanation

Correct answer: The rate at which population changes over a given period

The direct answer is A: population growth rate indicates how quickly the population changes during a specified period. The word ‘rate’ tells us to think about the speed or extent of change over time. It may describe an increase or, in some situations, a decrease. Option A is correct because it includes both change and a time period. Option B is wrong because the total number of people is the population size. Option C is wrong because people per square kilometre is population density, which relates population to area. Option D is wrong because females per 1,000 males is the sex ratio. These terms describe different population features and should not be mixed. Memory cue: growth rate means change through time; density means people per area; sex ratio means females compared with males.
