If there are 1700 births, 1200 deaths and net migration negative 800, what will total change be like?

Answer and explanation

Correct answer: Decrease of 300

The direct answer is A: a decrease of 300. First calculate natural increase: births − deaths = 1700 − 1200 = +500. The district or area gains 500 people from the difference between births and deaths. Next apply net migration: negative 800 means that migration causes a loss of 800 people, so it is written as −800. Add both effects: +500 + (−800) = −300. A negative total change means the population decreases by 300. Option A is correct. B changes the sign and incorrectly calls the result an increase. C reports only natural increase and ignores net migration. D adds the figures without considering that deaths and negative migration reduce population. Memory cue: calculate natural increase first, then add signed net migration. The minus sign is essential: the larger migration loss outweighs the natural gain.
