Bidhannagar or Salt Lake is a city in Bidhannagar Municipal Corporation of North 24 Parganas district in the Indian state of West Bengal. It is close to Kolkata and also a part of the area covered by Kolkata Metropolitan Development Authority (KMDA). It was developed between 1958 and 1965 as a planned satellite city to accommodate the burgeoning population of Kolkata.


At the 2011 census, Bidhannagar City had a population of 218,323 (Males 111,363; Females 106,960) in an area of approx 13.16 square km with a density of about 16,590 persons per square kilometer.[1] However, the area of Bidhannagar Municipality was 33.50 square km (much bigger than Bidhannagar City) because it includes East Kolkata Wetlands area, where very few floating people live.[2][1] Bidhannagar has an average literacy rate of 90.44% (higher than the national average of 74%),[3] with male literacy of 93.08% and female literacy of 87.69%.[4]

The city has the second highest proportion of graduates in the country (30.6 per cent), only after Sahibzada Ajit Singh Nagar, also known as Mohali, which has 34.4 per cent of its population as graduates. [1]

History of civic administration[edit]

Bidhannagar was originally developed and built under the direct administration of the Irrigation and Waterways Department of the Government of West Bengal. Initially, this planned city was under the South Dum Dum Municipality, then it came under the wings of the Public Works (Metropolitan Development) Department, which was renamed as the Urban Development Department in 1991. The whole area was divided into 5 sectors - Sector - I, Sector - II, Sector - III and Sector - IV as Residential Townships and Sector - V as Industrial Area.[6] An administrator was also appointed to control all the municipal activities there.


Ultimately in 1995, Bidhannagar got its own elected body called Bidhannagar Municipality consisting of 23 wards (later increased to 25 wards).[7] All the plots of land in Bidhanannagar are leasehold plots and the Urban Development Department (the Lessor) directly manages the land matters. East Kolkata Wetlands area is also included in Bidhannagar Municipality. The proposal for the merger of Bidhannagar Municipality with the Kolkata Municipal Corporation has been periodically mooted since 2011, but never realised due to different custodian of land and property tax-structures.[8] Kolkata Airport, Rajarhat-Gopalpur (Kaikhali, Teghoria, Baguiati, Hatiara, Kestopur), parts of South Dum Dum (Dum Dum Park, Bangur Avenue, Lake Town) and Bidhannagar are already brought together under the jurisdiction of the Bidhannagar Police Commissionerate. On 18 June 2015, Bidhannagar Municipal Corporation (BMC) was constituted by merging the existing municipal areas of Bidhannagar Municipality, Rajarhat-Gopalpur Municipality and the panchayat area of Mahishbathan II Gram Panchayat.[9] Now Bidhannagar has 14 wards (ward no. 28 to 41) under Bidhannagar Municipal Corporation.[10]

Nabadiganta Industrial Township Authority (NDITA) was created in January 2006. It supplies water; maintains sewerage, roads, street signals; furnishes important buildings and collects property tax and fees in Sector - V (excluded from the jurisdiction of Bidhannagar Municipal Corporation).[11]


The Bidhannagar Police Commissionerate is responsible for law enforcement in the city.

The Howrah Maidan - Salt Lake Sector V - Teghoria (Haldiram) Line (Line 2) of the Kolkata Metro is in operation since 14 February 2020 between Salt Lake Sector V and Salt Lake Stadium. The New GariaDum Dum Airport Line (Line 6) of the Kolkata Metro, which passes through the Salt Lake Bypass, is under-construction with cost inflation and delays[12][13]

Currently, the major IT corporates like TCS, Microsoft, Wipro etc. are having its campuses in the area. The area is also having many luxury malls like City Centre and Downtown mall and also many luxurious residencies.
