The economic growth is likely to be around 6.9 per cent in 2011-12. It was 8.4 per cent in the last fiscal. Government data says this is mainly due to sharp slowdown in manufacturing, agriculture and mining sectors. The Central Statistical organization's, CSO, growth projection is a tad lower than the 7 per cent forecast made by the Reserve Bank of India in itsquarterly monetary policy review last month. In its mid-year Economic Review, the government had also pegged growth at around 7.5 per cent. The current estimate is a sharply lower than the 9 per cent growth projection for 2011-12 made by the government in its pre-Budget survey in February last year. According to advance estimates, mining and quarrying is likely to witness a decline of 2.2 per cent, compared to a growth of 5 per cent a year ago.
