If in-migration to a city is high but urban services are growing slowly, what is the most likely result?

Correct answer: Service pressure and a greater possibility of informal settlements

The correct answer is A: service pressure and a greater possibility of informal settlements. In-migration means people enter a place from another area. These newcomers increase the demand for housing, water, sanitation, transport, schools, health care and employment. If services and infrastructure expand more slowly than the population, existing facilities become overcrowded and many people may not find affordable formal housing. Some may therefore live in unplanned or informal settlements. Option B is wrong because more people normally increase, not end, the demand for services. Option C is wrong because in-migration adds population unless other processes completely offset it. Option D is wrong because a growing population does not make a city uninhabited. Memory cue: when population growth is faster than service capacity, think “pressure, shortage and informality.”
