A constitutional amendment in 1991 gave Delhi a special status among the Union Territories; Delhi has its own legislative assembly with limited powers. The National Capital Territory of Delhi comprises nine districts, 27 tehsils, three statutory towns viz. Municipal Corporation of Delhi (MCD), New Delhi Municipal Committee (NDMC) and Delhi Cantonment Board (DCB), 59 census towns and 165 villages.Table 3.1: Delhi Last 10 Years (1991–2001) — Administrative Set Up (PDF).

Delhi is one of the oldest continually inhabited cities in the world. Having been the capital of several empires in ancient India, Delhi was a major city in the old trade routes from northwest India to the Gangetic Plains. Many ancient monuments, archaeological sites and remains of national importance have been erected in its history.Delhi Circle (N.C.T. of Delhi).

The Mughals built a section of the city (now known as Old City or Old Delhi) that served as the capital of Mughal Empire for a long period. During the British Raj, New Delhi was built as an administrative quarter of the city. New Delhi was declared the capital of India after India gained independence from British rule in 1947. As the seat of the Government of India, New Delhi houses important offices of the federal government, including the Parliament of India, making Delhi a powerhouse of Indian politics.

Delhi has grown up to be a cosmopolitan city owing to the immigration of people from across the country. Like many other large cities of the world, Delhi suffers from urbanisation problems such as pollution, traffic congestion, and scarcity of resources
