If large numbers of people aged 20 to 35 leave a region, what effect may occur on the local age structure?

Answer and explanation

Correct answer: The working-age share may decline

People aged 20 to 35 are generally part of the working-age population, and many are also in important reproductive ages. If large numbers leave a region, the local population loses a substantial share of workers and young adults. The working-age share can therefore decline, even if the total population does not fall by the same proportion.

Children and elderly people may then form a larger relative share of the remaining population. However, the child population will not automatically double, and elderly numbers need not decline because of this migration. The exact effect depends on the size and selectivity of the migration, but option A states the likely possibility. Thus it is the appropriate answer.
