Under which condition does the population of a region increase naturally?

Answer and explanation

Correct answer: When births exceed deaths

Natural population increase measures the change caused only by births and deaths. It is positive when births are more numerous than deaths, zero when they are equal, and negative when deaths exceed births. Migration is not included in natural increase, although it affects the total population change.

In this question, the condition for natural growth is therefore that births exceed deaths, making option B correct. If deaths exceeded births, natural change would be negative, so A is incorrect. When both are zero, natural change is zero, not an increase, and out-migration reduces total population rather than creating natural growth.
