In which condition will out migration especially affect age structure of an area?

Answer and explanation

Correct answer: When mainly young workers move out

Direct answer: A, when mainly young workers move out. Age structure means the proportion of people in different age groups, such as children, working-age adults, and older people. Out migration removes people from the area, but its effect depends on who leaves. If young workers leave in large numbers, the remaining population may contain relatively more children and older people and fewer working-age adults. This can also reduce the local labour force and increase the dependent share. Option A is correct because it identifies the age group that is migrating. Option B is wrong because no out migration cannot directly change age structure through out migration. Option C is wrong because equal movement of all age groups is less likely to change their proportions greatly. Option D is wrong because it describes no migration; equal births and deaths alone do not represent an out-migration effect. Memory cue: migration changes population composition most when migrants are concentrated in one age group.
