If births are 2800 deaths are 1700 and net migration is negative 400 what will total growth be?

Answer and explanation

Correct answer: 700

Direct answer: A, 700. Solve in two clear steps. Step 1: natural increase = births − deaths = 2,800 − 1,700 = 1,100. Step 2: total growth = natural increase + net migration = 1,100 + (−400) = 700. Thus the area still has positive growth, but it is smaller than the natural increase because more people left than entered. A is correct. B, 1,100, is only the natural increase and forgets the negative migration. C, 1,500, incorrectly adds 400 instead of subtracting it. D, 4,900, incorrectly combines the figures rather than applying the population-change formula. The negative sign is essential: it represents a net loss through migration. Memory cue: calculate births minus deaths first, then add the signed migration value.
