If birth rate is stable but out migration suddenly increases in an area what effect can it have on total population growth?

Answer and explanation

Correct answer: Total growth may decrease

The correct answer is A: total population growth may decrease. Out-migration means residents leave the area, so it subtracts from the population change of that area. If the birth rate remains stable but more people leave, the gain from births may be partly or fully offset. The final result also depends on deaths and any in-migration, so “may” is the accurate wording. A is correct because increased out-migration can reduce the net change. B is wrong because migration does not always double growth. C is wrong because movement of people does not automatically change the death rate to zero. D is wrong because population movement does not alter the physical area of a region. Memory cue: people entering add; people leaving subtract.
