Mumbai, formerly Bombay, is the capital of the Indian state of Maharashtra and the financial capital of India. With a population of 13,662,885, it is the second most populous city proper in the world. Along with the neighbouring suburbs of Navi Mumbai and Thane, it forms, at 19 million, the world's fifth most populous metropolitan area. Mumbai lies on the west coast of India and has a deep natural harbour. Mumbai's port handles over half of India's maritime cargo. Mumbai is the commercial and entertainment centre of India, generating 5% of India's GDP[3] and accounting for 25% of industrial output, 40% of maritime trade, and 70% of capital transactions to India's economy.[4] Mumbai is one of the world's top ten centres of commerce by global financial flow,[5] home to important financial institutions such as the Reserve Bank of India, the Bombay Stock Exchange, the National Stock Exchange of India and the corporate headquarters of many Indian companies and numerous multinational corporations. The city also houses India's Hindi film and television industry, known as Bollywood. Mumbai's business opportunities, as well as its potential to offer a better standard of living, attract migrants from all over India and, in turn, make the city a potpourri of many communities and cultures.
