If out-migration from a state is mostly of young people, what can be the long-term demographic result?

Correct answer: Future birth potential may decline

Correct answer: A. Young people often form an important part of the reproductive-age and working-age population. If many of them leave a state, fewer people may remain in age groups that could produce births in the future. This can reduce the state’s future birth potential and may also alter its age structure and dependency pattern. A says “may,” which is appropriate because the result depends on the number, sex composition, duration, and later return or replacement of migrants. B is wrong because out-migration does not automatically cause in-migration. C is impossible as a general conclusion; migration cannot make the death rate always zero. D is wrong because people leaving cannot immediately double the total population. Memory cue: when young adults leave, look ahead at the age structure and future births, not only at today’s population total.
