If total population is stable but the share of children is falling and the share of elderly people is rising, which conclusion is correct?

Answer and explanation

Correct answer: Size is stable but age structure is changing

Direct answer: A. Population size means the total number of people, whereas age structure means how that total is divided among children, working-age people and elderly people. These are related but different features. The total can remain stable while the proportions change: fewer children and more elderly people indicate an ageing age structure. This change can affect future needs for schools, jobs, pensions, healthcare and support services. B is wrong because a stable total does not show a population explosion. C is wrong because changing age composition requires appropriate planning. D is wrong because population structure is measured at a particular time and changes over time. Memory cue: stable total does not mean stable composition.
