In which condition can the positive effect of in-migration become a demographic advantage?

Correct answer: When incoming people get skills and employment

Direct answer: Option A. In-migration brings people into a receiving area. It can create pressure if facilities are inadequate, but it can become an advantage when migrants are able to use their skills in suitable work. Employed and skilled migrants may add labour, knowledge, entrepreneurship and demand for goods and services. They can contribute to production and support the local economy. Option A is correct because skills and employment help convert population movement into a productive demographic resource. Option B is wrong because the absence of services makes settlement and integration difficult. Option C is wrong because a complete lack of housing creates insecurity and overcrowding rather than an advantage. Option D is wrong because without jobs, migrants may face unemployment and the receiving area may experience additional social and economic pressure. The benefit is not automatic; it depends on opportunities, facilities and effective planning. Memory cue: migration becomes an asset when people can participate productively, not merely when they arrive.
