India\u2019s official data such as that on the IIP or GDP has often been dogged with controversy, the most recent of which was the rebasing of the GDP series soon after Narendra Modi assumed office. The rebased GDP didn\u2019t seem quite right since, even in the face of obvious economic distress, it bumped up growth significantly from the 5% or so levels it was at that point in time. But, apart from the fact that controversies arise each time a rebasing takes place, those who suspected Modi was behind the rosier numbers needed to keep in mind that the exercise was begun under the UPA and even the methodology was finalized then. Matters got worse when, while the Sudipto Mundle-panel\u2019s GDP back-series bumped up the UPA-2 average growth to 8% per year, this got lowered to 6.7% in the revised back-series versus the Modi government\u2019s average of 7.35%. That this data which lowered UPA-2 growth to below the NDA\u2019s was not released by the central statistics office (CSO) but was made public by Niti Aayog deputy chairman Rajiv Kumar added to the controversy since his was a political appointment.

The FY06-08 period, for instance, was one of scorching growth in investment, when gross fixed capital formation (GFCF) averaged around 31.5% of GDP, so it jelled with the fact that GDP growth averaged 9.5%. For the UPA period as a whole, GFCF-to-GDP averaged 31.8% and GDP grew at 7.8%. It is a bit difficult to believe, then, that a 28% or so, GFCF can produce an 8% GDP today; so has productivity shot up so dramatically? Nor were the inconsistencies related to just the investment data. During UPA-1, when GDP averaged 8%, credit grew at 29.3%; this fell to 16.3% as GDP growth fell to 6.7% in UPA-2. In which case, how is an 8.6% credit growth \u2013 the average since Modi came to power \u2013 giving an average GDP growth of 7.4%? Even so, former chief statistician of India TCA Anant put up a stellar defence of the back-series data, the most important of which was that a new series of corporate data \u2013 that boosted estimates of GDP \u2013 was available for recent years, but not for the years before that. To that extent, his argument was that, while this lowered GDP growth in the back-series, that was unfortunate since, once there was better quality data available, it made sense to use it. Matters have, however, really come to a head with the chairman and another non-government member of the National Statistical Commission (NSC) resigning as a result of which there are now no external members in the Commission to vouch for the integrity of the CSO data and process. This is all the more unfortunate since, apart from the controversy over Niti Aayog driving the GDP back-series computations, one of the areas of controversy is over how jobs have fared in the Modi period and, while the NSSO\u2019s employment survey for 2017-18 was to shed light over this, the trigger for the resignation appears to be the fact that the data has not been released by the government despite the NSC approving the report over a month ago. Since the chairman of the NSC said one of the reasons for his resignation was that he was not being taken seriously, it puts another cloud on the official data and strengthens the view that jobs growth in the Modi period has been poor.
