Why is population growth rate expressed in percentage?

Answer and explanation

Correct answer: So change can be compared with base population

The direct answer is A. A percentage expresses a change in relation to a base amount, treating the base as 100 parts. In population studies, the starting or previous population is the base. The basic formula is: percentage growth = (increase in population ÷ original population) × 100. This allows fair comparison between places of different sizes. For example, an increase of 100 people is 10% of a population of 1,000 but only 1% of a population of 10,000. Option A is correct because it explains why the base population matters. Option B is wrong because area is measured in square units such as square kilometres. Option C is wrong because river length is measured in distance units such as kilometres. Option D has no connection with population growth. Memory cue: percentage means “out of the original 100.”
