Which statement correctly relates declining growth rate and actual population size?

Answer and explanation

Correct answer: Total population can grow even if a positive rate declines

Direct answer: Option B is correct. Population size is the total number of people, whereas the growth rate is the speed or percentage at which that number changes. If the rate remains positive, the population continues to increase even when the rate becomes smaller. For example, growth of 3% followed by growth of 1% still adds people; it means the increase is slower, not that the total has fallen. Option A is wrong because a declining rate becomes population decline only when the rate is negative, or when deaths and out-migration exceed births and in-migration. Option B correctly describes a slowing positive increase. Option C is wrong because population size depends on births, deaths and migration as well as area. Option D is wrong because rate and size are related, although they are not identical measures. Memory cue: falling speed does not mean moving backward.
