I would be pretty keen on the real GDP numbers for these states, that would give us a much better sense of which state is doing what and also the aid and loans/grants raised by the concerned states. If we can access data in those lines, would be the real deal. As a matter of fact, a much more detailed data which can list up debt to gdp ratio, tax to gdp ratio, and more such data which can give us a sense of the real fiscal situation of the state.
I was going though the
data listed up at the wiki, and that gave a sense of a comparative analysis between nominal GDP from '04-'05 to '11-'12.
This data puts Bihar as a shining example of the good that has happened, coupled with smaller states that tend to get over looked, more importantly these are landlocked states and amongst the bigger states MH, TN and to an extent GJ have done better, rest put up a disappointing show, but then again, and I put a rider here, which is, these are nominal numbers, accounting the inflation, so one gets only a partial sense, and in some cases a very biased sense, of what is happening, and I'm no fan of nominal numbers.
One thing does stand out from this data, the smaller states have done much better, in fact some of them have done phenomenally well, though there are also examples of JH, and CH which have been a disappointment and no more.
