Delhi is the second most populous metropolis in India after Mumbai and the largest city in terms of area. With a population of 16.3 million in 2011, the city is also the eighth most populous metropolis 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. The NCR includes the neighbouring cities of Baghpat, Gurgaon, Sonepat, Faridabad, Ghaziabad, Noida, Greater Noida and other nearby towns, and has nearly 22.2 million residents. Although technically a federally administered union territory, the political administration of the NCT of Delhi today more closely resembles that of a state of India with its own legislature, high court and an executive council of ministers headed by a Chief Minister.
