This book traces the evolution and transformation of the Jharkhandi identity over the last half-century culminating in the formation of the Jharkhand state in November 2000. The book provides decade-wise detailed socio-economic data for Jharkhand and undivided Bihar, beginning with 1950, and correlates the performance of the Jharkhandi political formations in Lok Sabha elections with the development profile of Jharkhand (in relation to undivided Bihar). It would be immensely valuable to political analysts, political parties, economists, policy makers, advocates of smaller states in India, and the state governments of Jharkhand and present-day Bihar.
