Multi-year anal- yses of these data are made difficult by the many changes in state and district boundaries that have occurred since the first comprehensive census of independent India in 1961. Between 1961 and 2001, the number of states and union territories in India increased from 26 to 35, and the number of districts increased from 339 to 593. There were several changes in both names and boundaries. We document these changes and use them to construct regions of amalgamated districts with constant boundaries. There are 232 such regions for the entire period 1961-2001. These can be used to construct panel data sets that cover this forty-year period. ∗Contact information: Both authors are at the Delhi School of Economics (

Multi-year analyses of these data are made difficult by the many changes in state and district boundaries that have occurred since the first comprehensive census of independent India in 1961.
