In which situation will natural increase of population remain zero?

Answer and explanation

Correct answer: Births and deaths are equal

Answer: C, when births and deaths are equal. Natural increase is calculated by comparing births with deaths: natural increase = births − deaths. If the two numbers are equal, their difference is zero. For example, if a population has 100 births and 100 deaths during a period, its natural increase is zero, although migration could still change the total population. Option A gives a positive natural increase because births exceed deaths. Option B gives a negative natural increase because deaths exceed births. Option D concerns migration, not natural increase, so it may change total population but does not determine natural increase. Common warning: never include in-migration or out-migration in the birth-minus-death calculation.
