A city has zero net migration, but the average age of arrivals is 24 and the average age of departures is 55. What effect is likely?

Answer and explanation

Correct answer: The city's age composition may shift younger

The correct answer is A. Zero net migration means arrivals and departures balance in number, not in age. Younger arrivals replacing older departures can shift the city's age composition toward younger ages. The exact change in the city's average age depends on its starting age structure and the number of people involved, but zero net migration does not rule out a change in population composition.
