Why is the difference between net migration and total migration important while planning population growth?

Answer and explanation

Correct answer: Because the total number may remain stable while the incoming and outgoing groups change

Correct answer: A. Net migration is calculated by subtracting out-migration from in-migration. It shows the balance of movement and its effect on population size. Total, or gross, migration counts the movements in both directions together. For example, 1,000 people may enter and 1,000 may leave: net migration is zero, but total movement is 2,000. Such movement can still change the age, skills, occupations, languages and service needs of a place. A is correct because a stable net number does not mean that no people moved. B is wrong because net and total migration use different calculations. C is false because migration changes population size or composition. D is unrelated. Memory cue: net means the balance; total means all movement counted together.
