A region records 9600 births, 6400 deaths, 1800 in-migrants, and 2700 out-migrants. What is the total population change?

Answer and explanation

Correct answer: Increase of 2300

Total population change has two components: natural increase and net migration. Natural increase is births minus deaths, so it is \(9600-6400=3200\). Net migration is in-migrants minus out-migrants, giving \(1800-2700=-900\). The negative result means migration reduced the population by 900.

Combining the components gives \(3200+(-900)=2300\). Thus the region experienced an increase of 2300 people, so option A is correct. The figure 3200 counts only births and deaths and ignores outward migration. The other options do not match the combined demographic balance.
