New Delhi: Slippages in data collection have led to sharp variations in industrial growth estimates for January from 6.8 percent to 1.14 percent, compelling the government to fix the problem by setting up a panel.

Terming sharp revision in the industrial production data as "totally baffling", Finance Minister Pranab Mukherjee on Friday said he has asked the authorities concerned to look into the issue.
"I can understand if there is error in calculating 0.1 percent of 0.2 percent, but from 6.8 percent to 1.1 percent, it is totally baffling," Mukherjee told reporters here, commenting on the sharp revision of the IIP growth rate for January from 6.8 percent to 1.1 percent.
He further said: "We shall have to ensure that government data, their integrity should not be challenged...I have asked concerned authorities to look into it that why it has taken place and they should be much more careful in the future".
The Ministry of Statistics and Programme Implementation (MOSPI) yesterday revised the Index of Industrial Production (IIP) for January from 6.8 percent to 1.14 percent because of wrong calculation of sugar production during the month.
Chief Statistician T C A Anant had attributed the sharp downward revision in IIP data to incorrect reporting on sugar production by the Directorate of Sugar in the Ministry of Consumer Affairs, Food and Public Distribution.
According to Anant, "Subsequent to the release (of IIP data for January 2012), it has been detected ... that the sugar production was wrongly taken as 134.08 lakh tonnes in place of actual figure of 58.09 lakh tonnes".
He had said that due to this change and minor update of data received from other source agencies, the IIP for January 2012 has been revised from 187.9 to 177.9.
Also, Anant said, the cumulative index for the period April-January (2011-12) was revised from 4 percent to 3.4 percent.
