If working-age people leave an area in large numbers, which effect is possible?

Answer and explanation

Correct answer: Local labour availability and future age structure may change

Answer: D. Working-age people are an important part of the labour force. If many of them leave, the source area may have fewer workers for farms, businesses and services. Their departure can also alter the age composition: children and older people may form a larger share of those remaining. In the future, the number and timing of families and births may also be affected, but no fixed result is guaranteed. A is wrong because birth rates do not automatically double. B is wrong because people leaving does not automatically cause others to enter. C is impossible as a general conclusion. D correctly uses “may,” because the effects are possible rather than certain. Memory cue: selective migration changes not only numbers but also composition.
