In which situation will net migration be zero?

Answer and explanation

Correct answer: In-migration and out-migration are equal

The direct answer is A. Net migration measures the balance between people entering and leaving an area. It is calculated as in-migration minus out-migration. If 500 people enter and 500 leave, the calculation is 500 − 500 = 0, so migration itself causes no net gain or loss, even though many people have moved. B describes zero natural increase, because births and deaths are equal; it does not necessarily mean net migration is zero. C compares births with in-migration, which are different population processes and cannot establish the migration balance. D also compares unrelated quantities and does not show that entries and exits are equal. A is correct because the two migration flows exactly cancel each other. Memory cue: net migration = in − out; equal flows give zero.
