If age-selective out-migration is occurring in an area, what additional data should be checked?

Answer and explanation

Correct answer: The migrants’ ages and work status

Direct answer: Option A. Age-selective out-migration means that people of particular age groups, often working-age people, are leaving an area in greater numbers than other groups. This can change the size and composition of the remaining population. It may reduce the local workforce and increase the relative share of children or older dependants, affecting the dependency ratio and service needs. Therefore, planners should check migrants’ ages and work status, and compare them with the age and employment structure of those who remain. Option A is correct because it reveals which population groups are leaving and whether the area is losing workers. Options B, C and D concern physical geography and do not show the demographic composition of migration. Memory cue: when migration is age-selective, always inspect who is moving, especially age and work participation, not just the total number.
