The India Zone

Mumbai contributes 10% of all factory employment, 40% of all income tax collections, 60% of all customs duty collections, 20% of all central excise tax collections, 40% of India's foreign trade and Rupees 40 billion (US$ 9 billion) in corporate taxes.[21] A number of Indian financial institutions have headquarters in downtown Mumbai, including the Bombay Stock Exchange, the Reserve Bank of India, the National Stock Exchange of India, the Mint, and numerous conglomerates (including Tata Group, Godrej and Reliance). Many foreign banks and financial institutions also have branches in this area.

Up until the 1980s, Mumbai owed its prosperity largely to textile mills and the seaport, but the local economy has since been diversified to include engineering, diamond-polishing, healthcare and information technology. Mumbai’s status as the state capital means that state and federal 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 blue collar professions. The port and shipping industry too employs many residents, directly or indirectly.

The entertainment industry is the other major employer in Mumbai. Most of India's major television and satellite networks are headquartered in Mumbai, as well as its major publishing houses. The centre of the Hindi movie industry, Bollywood, is also located in Mumbai, along with its largest studios and movie production houses. Marathi television and film industries are also based in Mumbai.

Along with the rest of India, Mumbai, its commercial capital, has witnessed an economic boom since the liberalisation of 1991, the finance boom in the mid nineties and the IT, export, services and BPO boom in this decade. The middle class in Mumbai is the segment most impacted by this boom and is the driver behind the consequent consumer boom. Upward mobility among Mumbaikars has led to a direct increase in consumer spending.
