In which situation can the growth rate decline but the total population still keep increasing?

Answer and explanation

Correct answer: The growth rate remains positive but becomes lower than before

Direct answer: A. A growth rate measures the speed or percentage of change, while total population is the number of people. A population of 100 growing at 3% becomes 103. If it later grows at only 1%, it becomes about 104.03. Thus, the rate has declined from 3% to 1%, but the population still rises because the rate remains positive. Option A is correct. Option B is wrong because a negative growth rate generally means the total population is decreasing. Option C is wrong because deaths exceeding births create negative natural increase, although migration could alter a particular case; it does not by itself express the required situation. Option D is wrong because everyone leaving would reduce the population. Memory cue: a smaller positive rate still means growth; only zero stops growth and a negative rate reverses it.
