Delhi is the India's second-most-populous city after Mumbai, and the largest city in terms of area. With a population of 22 million in 2011, the city is the fourth-largest city in the world. The NCT and its urban region have been given the special status of National Capital Region (NCR) under the Constitution of India's 69th amendment act of 1991.

New Delhi is jointly administered by the federal government of India and the local government of Delhi, and is the capital of the NCT of Delhi.
