The demographics of India are inclusive of the second most populous country in the world, with over 1.21 billion people (2011 census), more than a sixth of the world's population. Already containing 17.5% of the world's population, India is projected to be the world's most populous country by 2025, surpassing China, its population reaching 1.6 billion by 2050. Its population growth rate is 1.41%, ranking 102nd in the world in 2010.

India has more than 50% of its population below the age of 25 and more than 65% below the age of 35. It is expected that, in 2020, the average age of an Indian will be 29 years, compared to 37 for China and 48 for Japan; and, by 2030, India's dependency ratio should be just over 0.4.

India has more than two thousand ethnic groups, and every major religion is represented, as are four major families of languages (Indo-European, Dravidian, Austroasiatic and Tibeto-Burman languages) as well as two language isolates (the Nihali language spoken in parts of Maharashtra and the Burushaski language spoken in parts of Jammu and Kashmir).

Mumbai /mʊmˈbaɪ/, formerly known as Bombay, is the capital city of the Indian state of Maharashtra. It is the most populous city in India, and the fourth most populous city in the world, with a total metropolitan area population of approximately 20.5 million. Along with the neighbouring urban areas, including the cities of Navi Mumbai and Thane, it is one of the most populous urban regions in the world. Mumbai lies on the west coast of India and has a deep natural harbour. In 2009, Mumbai was named an Alpha world city. It is also the wealthiest city in India, and has the highest GDP of any city in South, West or Central Asia. Mumbai has been ranked 6th among top 10 global cities on billionaire count, ahead of Shanghai, Paris and Los Angeles.

Dharavi (Hindi and Marathi: धारावी; Portuguese spelling Daravi; British Anglicised spelling Darravy, Dorrovy) is a slum and administrative ward, over parts of Sion, Bandra, Kurla and Kalina suburbs of Mumbai, India. It is sandwiched between Mahim in the west and Sion in the east, and spread over an area of 175 hectares, or 0.67 square miles (1.7 km²). In 1986, the population was estimated at 530,225, but modern Dharavi has a population of between 600,000 and over 1 million people. Dharavi is one of the largest slums in the world. It used to be the largest slum in Mumbai at one time, but as of 2011, there are four slums in Mumbai larger than Dharavi.

In most large cities, the floor space index (FSI) varies from 5 to 15 in the Central Business District (CBD) to about 0.5, or below, in the suburbs. In Mumbai the permitted FSI is uniform and in 1991 was fixed at 1.33. The regulations that restrict the FSI greatly reduce the floor space available for residence and business. In expensive Mumbai, Dharavi provides a cheap alternative where rents were as low as US$4 per month in 2006. Dharavi exports goods around the world. The total (and largely informal) turnover is estimated to be between US$500 million and over US$650 million per year.

Dharavi is situated between Mumbai's two main suburban railway lines, the Western and Central Railways. To its west are Mahim and Bandra, and to the north lies the Mithi River, which empties into the Arabian Sea through the Mahim Creek. To its south and east are Sion and Matunga. Both its location and poor drainage systems make Dharavi particularly vulnerable to floods during the wet season.
