Which option gives the correct calculation of natural increase?

Answer and explanation

Correct answer: Births minus deaths

Correct answer: A, natural increase equals births minus deaths. Natural increase measures the change produced by natural processes alone, so migration is not included in this calculation. Write the rule first: natural increase = number of births − number of deaths. If births are greater than deaths, the result is positive; if deaths are greater, the result is negative, indicating natural decrease. Option A is correct because it gives the correct order of subtraction. Option B reverses the order and would give the negative of natural increase. Option C is wrong because in-migration and area do not form the formula for natural increase. Option D is unrelated and has no standard demographic meaning. Do not confuse natural increase with total population change, which also considers people entering and leaving. Memory cue: births add naturally, deaths subtract naturally.
