If in-migration and births together equal deaths and out-migration, what will happen to the total population?

Correct answer: It will remain approximately stable

Answer: A, the population will remain approximately stable. Population change can be understood by balancing additions and subtractions. Births and in-migration add people to an area. Deaths and out-migration remove people. In simple form, net change = births + in-migration − deaths − out-migration. If the two adding components together equal the two subtracting components, net change is zero for that period. The total population therefore stays nearly the same, although people may still be being born, dying, arriving, or leaving. A is correct because it describes this balance. B is wrong because rapid growth requires additions to exceed removals. C is wrong because balance does not mean that everybody disappears; it means the total change is zero. D is wrong because density is a measure of people per unit area, not a result or substitute for population. Memory cue: equal additions and removals mean no net change.
