Occupations

Mumbai has traditionally owed its prosperity largely to its textile mills and its seaport till the 1980s. This has now been replaced by industries employing more skilled labour such as engineering, diamond polishing, healthcare and information technology. As Mumbai is the state capital, government employees make up a large percentage of the city's workforce. Mumbai also has a large unskilled and semi-skilled labour population, who primarily earn their livelihood as hawkers, taxi drivers, mechanics and other such proletarian professions. The port and shipping industry too employs many residents directly and indirectly. Like all other metropolitan cities, Mumbai also has a large influx of people from rural areas looking for employment.

The entertainment industry is the other major employer in Mumbai. Most of India's television and satellite networks are located in Mumbai, as well as the major publishing houses. A large number of the Hindi and English television shows are produced in Mumbai. The Hindi movie industry, Bollywood, is also located in Mumbai, along with the largest studios and production houses.
