Nagpur is estimated to be the 114th largest city and the 143rd largest urban area in the world in 2006 in terms of population. Nagpur is also important geographically as it lies practically at the centre of India with the country's geographical centre (Zero Mile) being situated here. Moreover, Nagpur is well-known throughout India as a trade centre for high-quality oranges grown in the surrounding region and hence the city is also known as Santra Nagari (Marathi for 'Orange City'). Recently, the city celebrated 300 years of its establishment.

Economy
Nagpur has been the centre of commerce in the Vidarbha region since early days and currently is a large trading centre for a number of commodities and services.
Currently a significant number of industries are located within the vicinity of Nagpur city. The Butibori industrial area is the largest in all of Asia in terms of area. The estate's largest unit is Indo Rama Synthetics, which manufactures synthetic polyester yarn. Other units in Butibori include the power transmission company KEC, Hyundai Unitech, ACC Nihon Castings Ltd. The estate also houses a number of other textile units besides several medium-sized units that manufacture a variety of products. In addition, the first food park in the state of Maharashtra is located in the estate.Though Butibori could not quite live up to its original promise, industrial activity is picking up due to the saturation in the Mumbai-Thane-Pune belt.

The Hingna industrial estate located on the western fringes of the city is made up of around 900 small and medium industrial units. The major ones among them are tractor manufacturing plant of Mahindra and Mahindra, casting units of NECO Ltd. (the country's largest casting group), units of International Combustions, Bajaj Auto group, Candico (the SECOND largest confectionery manufacturing plant in India), Ajanta toothbrushes, Sanvijay Group (largest steel rolling group of companies for long products in Central India) and Vicco Laboratories, which specializes in ayurvedic products. Moreover, Nagpur is also home to well-known ice-cream maker Dinshaws and the nationally famous sweetmaker Haldiram's.

Nagpur is also the next most favoured Information Technology (IT) destination in Maharashtra after Mumbai and Pune due to factors favorable to the IT industry like the city's location, good infrastructure (the spick and span four laned roads of Nagpur give it a leverage compared to Pune and even Banglore), and the availability of a large and relatively cheap pool of skilled labor from local and regional educational institutions. In the near future, Nagpur will also have a Rs. 10,000 crore Special Economic Zone (SEZ) attached that has already attracted some of India's top-notch Information Technology companies like Satyam Computer Services and L&T Infocity.
