If a country's birth rate is 26 per thousand and death rate is 11 per thousand, what is the natural increase rate per thousand?

Answer and explanation

Correct answer: 15 per thousand

Natural increase measures population change caused by births and deaths only. It does not include immigration or emigration. The standard calculation is the birth rate minus the death rate, using the same unit, such as per thousand population.

Here, the birth rate is 26 per thousand and the death rate is 11 per thousand. Therefore, \(26-11=15\) per thousand. This positive value means that, before considering migration, there are 15 more people per thousand than the number lost through deaths. Adding the two rates would be wrong because deaths reduce population. Thus, option B is correct.
