Migrant population, being a non-native population, is vulnerable and is exposed to many health problems. Most of the health problems of migrants are ascribed to their migration to urban areas, decreased awareness about local health facility, inability to cope with psychological stress, unhealthy sexual practices, and frequent migration. Other factors are: food insecurity, climate, and other environmental hazards. According to the National Sample Survey 2007-08, the number of migrant households per 1000 households in India was 33 in urban areas. Two-thirds of the households migrated for employment-related reasons. Another 21% of the households migrated for study purposes.
