What is the most accurate meaning of net migration in population change?

Answer and explanation

Correct answer: The difference between in-migration and out-migration

Answer: C. Net migration measures the balance of people entering and leaving a particular area during a period. It is calculated as in-migration minus out-migration. If more people enter than leave, net migration is positive. If more people leave than enter, it is negative. If the numbers are equal, it is zero. A is incorrect because births and deaths are used to calculate natural increase, not net migration. B combines unrelated measures and is not a population-change formula. D also combines unrelated ideas and cannot represent migration. C gives both the correct components and their relationship. Memory cue: “net” means what remains after incoming people are balanced against outgoing people.
