When can migration change a region's age structure without any immediate change in birth rates?

Answer and explanation

Correct answer: When migrants are concentrated in particular age groups

Migration changes the age distribution when migrants are concentrated in particular age groups. For example, young adults moving for education or work can increase the working-age share in the destination and reduce it in the place they leave, even without an immediate change in births. If migrants have the same age distribution as residents, the overall proportions are less likely to change. Option A is correct.
