What does the percentage form of population growth show better?

Answer and explanation

Correct answer: Proportion of growth relative to the base population

Answer: A, the proportion of growth relative to the base population. Percentage growth compares the increase with the population at the beginning of the period. A simple expression is percentage growth = (increase ÷ base population) × 100. For example, an increase of 10,000 is 10% for a base of 100,000, but only 1% for a base of 1,000,000. Therefore, the percentage form makes comparison between differently sized populations fairer than absolute numbers alone. B describes area, not population growth. C concerns agriculture and gives no population-growth measure. D concerns rainfall, not population. A common confusion is to treat a large numerical increase as automatically a high growth rate; the denominator, or base population, matters.
