Unequal access to resources, employment and income along with its trend of steady magnification results into multiple social and economic depreciations. The issue of income inequality at macro level, i.e. national and state level has been well focused whereas analysis of micro-level disparities in this aspect has yet to be explored significantly. The development plans, at presents, rely on decentralized planning processes where the micro level sectoral and spatial variation of income should be given importance. Purulia district is one of the most backward districts in West Bengal in perspective of all the dimensions of human development accompanied with the income inequality at a considerable magnitude. The present study attempts to assess the intra-district income inequalities between different social, ethnic and religious classes. The study analyses the profiles of income distributions of different competitive classes carefully. It also plotted the relative deprivation curve. The result of the analyses has been critically discussed for an amicable conclusion.
