If an area has 1200 births and 800 deaths, what will be the natural increase?

Answer and explanation

Correct answer: 400

Correct answer: B, 400. Natural increase is calculated by subtracting deaths from births, without including migration. Step 1: identify births, 1200. Step 2: identify deaths, 800. Step 3: apply the rule: natural increase = births − deaths. Step 4: calculate 1200 − 800 = 400. Therefore, the area has a natural increase of 400 people for the stated period. Option A, 200, is an incorrect subtraction and does not follow the given numbers. Option B is correct because it is the exact difference between births and deaths. Option C, 800, is only the number of deaths, not the difference. Option D, 2000, adds births and deaths, but addition is not the rule for natural increase. Migration would be considered separately for total population change. Memory cue: for natural increase, subtract deaths from births: B minus D.
