All India GDP is supplied by the Central Statistics Office (CSO) but the state data are supplied by the directorate of economics and statistics of the respective state governments. The upshot is that the total of the GDPs of the states and union territories does not tally with the all-India figure by a fairly big margin. The question here is: which GDP growth number should the policy makers take? perhaps CSO’s estimates are more accurate, but on what growth figure should states base their economic policies? Perhaps, we need an independent central department maybe CSO, to give out estimates of the GDP of states.
