If the population changes from 3,000 to 2,800, what is this change called?

Answer and explanation

Correct answer: Population decline

The direct answer is B: population decline. First compare the two numbers. The final population is 2,800 and the initial population was 3,000. Subtracting gives 3,000 − 2,800 = 200, so the population has decreased by 200 people. A decrease in the number of people is called population decline or population decrease. Option A is wrong because population growth means that the final number is greater than the initial number. Option B is correct because the final number is lower. Option C is wrong because zero population growth means there is no net change, such as 3,000 remaining 3,000. Option D is wrong because the population has not increased rapidly; it has fallen. Memory cue: final number lower means decline, equal means zero growth, and higher means growth.
