Why cannot a decline in the population growth rate be treated as population decline?

Answer and explanation

Correct answer: Because if the rate remains positive, the total population still increases

Direct answer: A is correct. A growth rate tells us how quickly the population is changing, while population decline means that the total number of people has actually become smaller. If the rate falls from 3% to 1%, growth has slowed, but 1% is still positive, so the population continues to increase. For example, 1,000 people growing at 1% become 1,010 people. A is correct because it distinguishes a slower increase from an actual decrease. B is wrong because a rate has a clear mathematical and demographic meaning. C is wrong because populations are not always zero. D is wrong because it makes an unsupported claim about death and birth rates and is not needed to explain the difference. Memory cue: “lower growth” does not automatically mean “lower population”; check whether the rate is positive, zero, or negative.
