Buoyed by the CSO's first quarter growth estimate of 8.8 per cent in fiscal 2011, the highest since the last quarter of 2007-08, the planners are already at work on an approach paper with a dictum for a 10 per cent target for the 12th Plan (2012-17), around which everything should presumably evolve. An analysis of the data dimensions in CSO's press release does not lend itself to the optimism in evidence in the Establishment. No wonder, the Finance Minister, Mr Pranab Mukherjee, has conceded that the estimates may undergo revision as more data become available for CSO in regard to the level of aggregate demand in the economy.
