If immigration and emigration are equal in an area, total growth will mainly depend on what?

Answer and explanation

Correct answer: Difference between births and deaths

Direct answer: Option A is correct. Total population change can be understood as natural increase plus net migration. Natural increase is births minus deaths, while net migration is immigration minus emigration. If immigration and emigration are equal, their difference is zero, so migration neither adds to nor subtracts from the total change. The main remaining demographic component is therefore the difference between births and deaths. Option B is wrong because area may affect density but does not by itself determine population growth. Option C describes people per unit area, not the processes causing the change. Option D may influence livelihoods in some places, but it is not the direct calculation here. Memory cue: equal in-migration and out-migration cancel; then check births minus deaths.
