If population decreases from 20 lakh to 18 lakh what will it be called?

Answer and explanation

Correct answer: Population decline

The correct answer is B: population decline. The population changes from 20 lakh to 18 lakh, so the later number is smaller than the earlier number. The amount of decrease is 20 lakh − 18 lakh = 2 lakh. A fall in the total number of people is called population decline or population decrease. Option A is wrong because population growth means that the number becomes larger. Option B is correct because the number has fallen. Option C means the number of people living per unit of area; density requires both population and area, so these figures alone do not describe density. Option D is wrong because the question gives no birth-rate information, and a birth-rate increase is not the name for a fall in total population. Memory cue: compare the arrow of change—up means growth, down means decline.
