If a large number of skilled workers aged 25-40 migrate out of a region, what is the most likely demographic effect?

Answer and explanation

Correct answer: The working-age share may decline and dependency may rise

People aged 25–40 usually belong to the economically active part of the working-age population. If many skilled workers in this age group leave a region, the origin region loses a substantial part of its labour force. The remaining population may contain relatively larger shares of children and older people, even if their actual numbers have not changed. This changes the age composition and can increase the burden placed on each remaining worker.

Therefore, option A is the best answer: the working-age share may fall and the dependency burden may rise. The word “may” is important because the exact result depends on the numbers and ages of migrants and those left behind. Children do not immediately disappear, elderly numbers need not decline, and the age structure cannot be assumed to remain unchanged. The other choices make absolute claims that do not follow.
