If birth rate is lower than death rate but immigration plus births exceed deaths plus emigration, what will be the total change?

Answer and explanation

Correct answer: Positive

The correct answer is A: the total population change will be positive. Begin by separating natural change from migration change. Natural change equals births minus deaths. Since births are fewer than deaths, natural change is negative. However, total change includes immigration and emigration as well: total change = births + immigration − deaths − emigration. The question states that births plus immigration are greater than deaths plus emigration, so the final result is above zero. Option A is correct because the complete balance is positive. Option B would describe the result only if the reducing components were larger overall. Option C is wrong because the components are not equal; the question says the adding side is greater. Option D is wrong because the direction of change can be determined from the stated comparison. Memory cue: never judge total population change from births and deaths alone; always include migration.
