Which indicator is most useful to know the pace of population growth?

Answer and explanation

Correct answer: Growth rate

Direct answer: Option A, growth rate, is correct. The pace of growth means how quickly a population changes during a stated period. Growth rate expresses this change in relation to the population, commonly as a percentage. A simple form is: growth rate = population increase divided by the initial population, multiplied by 100. This allows us to compare areas or periods of different size. Option B describes the physical character of soil and does not measure population change. Option C describes a river, not the speed of demographic change. Option D counts wildlife, not human population growth. These factors may matter in environmental or geographical studies, but they are not the requested population indicator. Memory cue: when the question asks “how fast,” look for a rate rather than a size, feature or count.
