If birth rate falls and life expectancy rises, what change in population structure is possible?

Answer and explanation

Correct answer: The share of the elderly population may increase

The direct answer is A. Birth rate describes the frequency of births, while life expectancy is the average length of life expected under current conditions. If fewer children are born and people live longer, children may form a smaller share of the total population while more people survive into older age groups. Over time, this can make the population structure older and increase the need for elderly health care, pensions, and support services. Option A is correct because it states a possible structural change, not an immediate certainty in every place. Option B is impossible because a falling birth rate does not turn existing people into infants. Option C is wrong because these trends do not make the population disappear immediately; population change takes time and also depends on deaths and migration. Option D is wrong because migration depends on movement between places and is not determined automatically by birth rate or life expectancy. Memory cue: fewer births plus longer lives can mean an ageing population.
