If a region records 2400 births and 1600 deaths, what is the natural increase?

Answer and explanation

Correct answer: 800

Natural increase measures the change caused only by births and deaths. It is found by subtracting the number of deaths from the number of births: \(\text{natural increase}=\text{births}-\text{deaths}\). For this region, the calculation is \(2400-1600=800\). Therefore the population gains 800 people through natural increase.

The figures are counts of events during the same period, so no rate conversion is needed. Adding births and deaths gives 4000, but that is the total number of demographic events, not the net increase. The values 600 and 1000 do not result from the required subtraction. Hence option B, 800, is the correct choice.
