If a region has a high birth rate and high out-migration, how should its total population change be concluded?

Answer and explanation

Correct answer: It will be decided by births, deaths and migration together

Answer: C. Total population change is not determined by one factor alone. A useful relationship is: total change = births − deaths + in-migration − out-migration. A high birth rate adds people, while high out-migration removes people; deaths also reduce the population, and in-migration adds to it. Without knowing all these quantities, we cannot say whether the total population will rise, fall or remain almost unchanged. A is incomplete because it ignores deaths and migration. B is also incomplete because it ignores births and deaths. D is wrong because area tells us about land, not directly about the number of people. Memory cue: add births and arrivals; subtract deaths and departures.
