If an area's actual growth is zero but both in migration and out migration are high what can it mean?

Answer and explanation

Correct answer: Total number is stable but population composition may change

Answer: A, the total population can remain stable while its composition changes. Actual or total growth depends on births, deaths, and net migration. Net migration is the difference between in-migration and out-migration. If roughly equal numbers enter and leave, their net effect on the total is zero, so the population count may not change. However, the people who enter may differ from those who leave in age, sex, education, occupation, or family situation. Therefore, the age structure, workforce, skills, and demand for services may change even when the total number stays constant. A is correct because it distinguishes gross movement from net change. B is wrong because high in- and out-migration means many people moved. C is wrong because migration can strongly affect composition and services even with zero net effect. D is wrong because population can still be counted. Memory cue: zero net migration does not mean zero migration.
