If 1000 people enter a region and 700 leave it, what is the net migration?

Answer and explanation

Correct answer: Increase of 300

Net migration measures the balance between people entering and people leaving a region. In-migration adds people to the population, while out-migration removes people. Therefore, net migration is calculated as in-migration minus out-migration. A positive result indicates a net increase; a negative result would indicate a net loss.

Here, the number entering is 1000 and the number leaving is 700. Thus, net migration is \(1000-700=300\). Since the result is positive, the region has an increase of 300 people due to migration. The total of 1700 is not the net value; it counts both flows without showing their balance. Therefore, option A is correct.
