If a country has a birth rate of 16 per thousand and a death rate of 11 per thousand, what is the natural increase rate in percent?

Answer and explanation

Correct answer: 0.5 percent

Natural increase is the birth rate minus the death rate. The given rates are per thousand, but the answer choices are percentages, so the result must be converted. Since one thousand equals one hundred percent in the rate conversion context, a rate per thousand is divided by 10 to express it as a percent.

The natural increase is \(16-11=5\) per thousand. Converting it gives \(5\div10=0.5\) percent. Thus the country gains five persons per thousand through natural change, equivalent to half a percent of the population. The answer is not 5 percent, because that would confuse “per thousand” with “percent.” Option A is correct.
