In which age structure may future demand for jobs rise rapidly?

Correct answer: Where the young population is large

A large young population can create strong future pressure on employment. Children and adolescents do not usually enter the workforce immediately, but as they grow older, many will seek jobs at roughly the same time. This can also increase demand for schools, vocational training, higher education, transport, housing, and public services. The result can be a demographic opportunity if the economy creates enough productive work, but it can become unemployment or underemployment if job creation and skill development are inadequate.

Option A is correct because a large youth cohort will eventually move into working ages and enlarge the potential labour force. Options B, C, and D describe populations with few or no young entrants, so they do not imply rapidly rising future demand for jobs. The word “may” is important: a young population creates potential demand, but the actual outcome depends on education, health, economic growth, and labour-market planning. Therefore, A is the strongest choice.
