Natural increase in population is determined by what?

Answer and explanation

Correct answer: Difference between births and deaths

Direct answer: Option A. Natural increase is the change produced by births and deaths within a population. It is found by subtracting the death rate from the birth rate, or, when using counts, by subtracting deaths from births. If births are greater than deaths, natural increase is positive. If deaths are greater than births, it is negative. Migration is not included in natural increase because migration is the movement of people between places, not a natural event occurring through birth or death. Option A is correct. Option B is wrong because migration belongs to migration balance and can be studied separately. Option C is wrong because area helps describe density, not natural increase. Option D is wrong because literacy may be related to demographic conditions but is not the calculation. Memory cue: “natural” means births minus deaths; add migration only when discussing total population change.
