West Bengal is the state with highest population density in India. The state is dotted with several small and medium towns and cities. Historically, the main source of income of the people of West Bengal has been farming, and, as a consequence, the state previously had a large rural population skew. At the turn of the 20th century, however, the role of industry in West Bengal increased substantially, leading to a population move into urban areas.
After the partition of India in 1947, the province of Bengal was divided into two major parts: the eastern region forming East Pakistan -- which became Bangladesh — and the state of West Bengal. Scores of refugees from the eastern part came to West Bengal, leading to the start of new urban areas, and contrubuting to the congestion of already established cities like Kolkata.
