Noida in the context of ISO 15919

New Delhi is the capital of India and a part of the National Capital Territory of Delhi (NCT). New Delhi is the seat of all three branches of the Government of India, hosting the Rashtrapati Bhavan (Presidential Palace), Sansad Bhavan (Parliament House), and the Supreme Court. New Delhi is a municipality within the NCT, administered by the New Delhi Municipal Council (NDMC), which covers mostly Lutyens' Delhi and a few adjacent areas. The municipal area is part of a larger administrative district, the New Delhi district.

Although colloquially Delhi and New Delhi are used interchangeably to refer to the National Capital Territory of Delhi, both are distinct entities, with the municipality and the New Delhi district forming a relatively small part within the megacity of Delhi. The National Capital Region is an even larger entity, comprising the entire NCT along with adjoining districts in the two neighbouring states forming a continuously built-up area with it, including Ghaziabad, Noida, Greater Noida, Meerut, YEIDA City, Gurgaon, and Faridabad.

The National Capital Region (NCR; Rāṣṭrīya Rājadhānī Kṣetra) is a region centred on the city of Delhi, a special union territory of India that hosts the country's capital city New Delhi. It encompasses the entirety of Delhi and a number of adjacent districts from the states of Haryana, Uttar Pradesh, and Rajasthan. The NCR and the associated National Capital Region Planning Board (NCRPB) were created in 1985 to plan the development of the region and to evolve "harmonized policies for the control of land-uses and development of infrastructure" in the region. Prominent cities of the NCR are Delhi, New Delhi, Faridabad, Gurgaon, Noida, Ghaziabad and Meerut.

The NCR is a mixed, rural-urban region, with a population of over 46,069,000 and an urbanisation of 62.6 percent. There are also areas like the Aravalli ridge, forests, wildlife and bird sanctuaries. The Delhi Extended Urban Agglomeration, the inner part of the NCR, had an estimated GDP of $370 billion (measured in terms of GDP PPP) in 2015–16. Despite being a part of the NCR, the Government of India's think tank, NITI Aayog, listed the Nuh district of Haryana as the most underdeveloped across India's 739 districts.

Greater Noida is a planned city located in the Gautam Buddha Nagar district of the Indian state of Uttar Pradesh. The city was created as an extension of the area under the UP Industrial Area Development Act, of 1976.

The city is administered by the Greater Noida Industrial Development Authority (GNIDA).

Noida was one of several planned cities developed in the 1980s to address rapid population growth in metropolitan areas such as Delhi, Mumbai, and Kolkata. However, population growth in Noida surpassed early projections, prompting the Government of Uttar Pradesh to plan an extension of the city — later developed as Greater Noida.

Meerut is also the second-most populous city in the NCR, after Delhi. As of 2025, Meerut’s urban (metro) population is estimated at ≈ 1.875 million. The population of Meerut Municipal Corporation is projected to be about 1.907 million, while the wider Meerut metropolitan region is estimated at approximately 2.077 million. Meerut is among the most populous cities in NCR, after Delhi and Ghaziabad.

In 1803, Meerut was as a significant location during the British colonial era, serving as the site of one of India’s largest cantonments. Meerut was one of the first locations where the 1857 rebellion against British rule began. It has been called the "Sports City of India" due to its sports goods industry. Meerut produces large number of musical instruments in India. It is also one of Asia's largest gold markets.
