In which situation will natural increase be negative?

Answer and explanation

Correct answer: Deaths exceed births

Correct answer: B. Natural increase is calculated from births minus deaths, without including migration. Therefore, if deaths are greater than births, the result is negative. For example, if a population has 8 births and 10 deaths during a period, the natural increase is 8 − 10 = −2 per the chosen population unit. B is correct because deaths exceed births. A is wrong because births exceeding deaths produce positive natural increase. C is wrong because equal births and deaths produce zero natural increase, not a negative value. D is wrong because inward migration affects total population change but is not part of natural increase. The broader population change can be expressed as natural increase plus net migration, but the word “natural” limits the calculation to births and deaths. Memory cue: natural increase = births − deaths; a negative answer means deaths are greater.
