In which condition can population composition change even when net migration is zero?

Answer and explanation

Correct answer: The numbers arriving and leaving are equal, but their age groups are different

Direct answer: Option A is correct. Net migration measures the numerical balance: in-migration minus out-migration. If 100 people enter and 100 people leave, net migration is zero. However, the people entering and leaving may not have the same characteristics. For example, if mostly young adults leave while people of another age group enter, the total number may remain unchanged but the age composition changes. The same idea can apply to sex, occupation or other population characteristics. Option B is not the best answer because no migration alone does not describe a migration-driven composition change. Option C gives equal births and deaths with no migration, so it provides no stated process for this change. Option D changes the area, not the composition of people. The key warning is that a zero net total does not mean zero movement and does not guarantee an unchanged population structure.
