Gross State Domestic Product of Karnataka

In this article, I have tried to explain the changes in methodology and sources of data made during the recent new base year revision from 2004-05 to 2011-12. Due to changes in institutional sectors, increased coverage of private corporate data base (Ministry of Corporate Affairs MCA -21 database) and shifting to enterprise approach from Establishment approach in Annual Survey of Industries (ASI) surveys, the GSDP of Karnataka increased substantially by 25% over the old series. This article also depicts the share of GSDP worked out by Central Statistics Office (CSO) and that worked out by the State DES. It shows that a significant share of 75% is estimated by the CSO and the rest by the DES. Sector wise changes in methodology and data sources leading to increase / decrease in GSVA are also covered in the article. Due to changes in methodology and data sources to old series, in the old series, the other services sector was shown into 11 different sub sectors compared to the new series, wherein only 4 sub-sectors are considered. Some suggestions are made which may be considered in the coming base year revision, so that the limitations of the 2011-12 base year revision can be minimised.
