If a region records 800 births and 500 deaths, what is the natural increase?

Answer and explanation

Correct answer: 300

Natural increase measures the change produced only by births and deaths. It is calculated by subtracting the number of deaths from the number of births: \(800-500=300\). Therefore, the region has a natural increase of 300 people, so option D is correct.

Migration is not included in this calculation. If 100 people entered or left the region, that would affect total population change, but it would not alter the natural increase calculated from births and deaths. The answer is an absolute number of people because the question gives counts, not rates. A rate would require a population base and usually a time period, neither of which is needed here.
