Why can an area have high growth rate but low absolute growth?

Answer and explanation

Correct answer: Because the initial population is very small

The direct answer is A: a small initial population can show a high percentage growth rate even when only a small number of people are added. Growth rate is calculated relative to the starting population. For instance, an increase from 100 to 110 is an absolute gain of only 10 people but a growth rate of 10%. If a large population gained 10 people, its percentage rate would be much lower. Option A is correct because a small denominator makes a modest numerical increase appear large as a percentage. Option B is wrong because a large starting population usually produces a lower percentage for the same small increase. Option C is wrong because zero growth produces neither a positive rate nor an increase. Option D is wrong because area and birth rate are different concepts: area measures space, while birth rate measures births relative to population. Memory cue: small base, big percentage.
