What is a possible result of increased out-migration in population growth of an area?

Answer and explanation

Correct answer: The working-age group may decline

Correct answer: A, the working-age group may decline. Out-migration means people leave an area for another place. If many of those leaving are working-age adults, the source area can lose part of its labour force and the proportion of working-age people may fall. The total population may also decrease or grow more slowly, but the exact result depends on the number and characteristics of migrants. B is not automatic; the birth rate depends on several social and demographic factors. C uses the absolute word “always” and has no basis. D is incorrect because actual population change includes natural increase and net migration; substantial out-migration can make actual growth lower than natural increase. Memory cue: migration changes both population size and composition, especially when migrants are concentrated in one age group.
