Therefore, for most migrants, moving to a city is a sound decision that is likely to benefit their well-being and strengthen their resilience to adversity. Migrants are often faced with legal, cultural and social barriers and obstacles to accessing formal housing, employment, education, health and other social services. These barriers may force them to live in conditions of exclusion, segregation and vulnerability. Migrant women, for instance, are more likely to work in low-paid, irregular, and potentially exploitive jobs, often in the informal sector.
