If the elderly population is increasing but in-migration of working-age people is also rapid, what effect may occur on elderly dependency?

Answer and explanation

Correct answer: It may remain more stable or rise more slowly

Elderly dependency is generally calculated as the elderly population divided by the working-age population, multiplied by 100. An increase in the elderly numerator tends to raise the ratio, but rapid in-migration of working-age adults enlarges the denominator. If the denominator grows sufficiently quickly, elderly persons per 100 working-age people may increase slowly or remain relatively stable. Migration does not remove population ageing, so option C is incorrect. Option A is too absolute, and D confuses elderly dependency with child dependency. Thus, option B is correct.
