Kolkata Population

A resident of Kolkata is referred to via the demonym Calcuttan or Kolkatan. According to provisional results of the 2011 national census, Kolkata district, which occupies an area of 185 km2 (71 sq mi), had a population of 4,486,679; its population density was 24,252 /km2 (62,810 /sq mi). This represents a decline of 1.88% during the decade 2001–11. The sex ratio is 899 females per 1000 males—lower than the national average. The ratio is depressed by the influx of working males from surrounding rural areas, from the rest of West Bengal, and from neighbouring states, mainly Bihar, Uttar Pradesh, and Orissa; these men commonly leave their families behind. Kolkata’s literacy rate of 87.14% exceeds the all-India average of 74%. The urban agglomeration had a population of 14,112,536 in 2011.

As of 2003, about one-third of the population, or 1.5 million people, lived in 3,500 unregistered squatter-occupied and 2,011 registered slums.The authorised slums (with access to basic services like water, latrines, trash removal by the Kolkata Municipal Corporation) can be broadly divided into two groups—bustees, in which slum dwellers have some long term tenancy agreement with the landowners; and udbastu colonies, settlements which had been leased to refugees from present-day Bangladesh by the Government. The unauthorised slums (devoid of basic services provided by the municipality) are occupied by squatters who started living on encroached lands—mainly along canals, railway lines and roads. According to the 2005 National Family Health Survey, around 14% of the households in Kolkata were poor, while 33% lived in slums, indicating a substantial proportion of households in slum areas were better off economically than the bottom quarter of urban households in terms of wealth status. Mother Teresa was awarded the Noble Peace Prize for founding and working with the Missionaries of Charity in Kolkata—an organisation “whose primary task was to love and care for those persons nobody was prepared to look after”.
