Development is a multi faced process by which a nation improves the economic, political, and social well-being of its people and it has spatio-temporal dimension. Inter-regional disparity has been an integral feature of the history of India’s socio-economic development. The present paper analysed district level disparity in West Bengal, India in terms of demographic development using fourteen indicators related to level of urbanisation, literacy, sex ratio and diversification of rural economy. Data of Census of India (2011) was analysed using Z score and Composite Standard Score to determine the relative level of disparity among the districts. It was found that Darjiling, Hooghly, Howrah, North 24 Parganas are most developed districts; Jalpaiguri, Dakshin Dinajpur, Murshidabad, Burdwan, Birbhum, Purba and Paschim Medinipur, Nadia and South 24 Parganas are moderately developed; and Puruliya, Bankura, Cooch Behar, Maldah, Uttar Dinajpur are least developed. Decentralised distribution of infrastructural investment can minimize regional imbalances.
