Why is population growth shown in percentage?

Answer and explanation

Correct answer: So comparison of different areas becomes easier

The correct answer is A: percentage makes comparison between different areas easier. A raw increase can be misleading because areas may begin with very different population sizes. For example, an increase of 10,000 people may be large for a small town but small for a huge city. Percentage expresses the increase in relation to the starting population, allowing a fairer comparison of growth rates. Option A states this purpose. Option B is wrong because showing population growth as a percentage cannot reduce river depth. Option C is unrelated to population measurement; percentages do not change mountain size. Option D is also unrelated because rainfall is a weather or climate phenomenon. A percentage is a relative measure, not merely a count of additional people. Memory cue: percentage puts growth on a common scale for comparison.
