The PMO has set up five committees to review the data for GDP estimates, provide for mechanisms to ensure "data integrity" and come up with industry-wise and geography-wise disaggregated data - something that is not available in the current system. "These committees are expected to cover the requirement of statistics for estimation of GDP, data governance for quality, timelines and credibility of collected data and derived estimates, provide for data integrity and audit trials of a National Statistical System," the Ministry of Statistics and Programme Implementation said in a directive. The exercise, according to National Statistical Commission Chairman RB Barman, will make monitoring the performance evaluation of data more effective.
