A group of more than a hundred experts sounded a pre-election alarm Friday over Indian economic data, accusing Prime Minister Narendra Modi's government of tweaking or burying unwelcoming numbers.
Modi is vulnerable over his economic record in the polls starting on April 11, in particular a failure to meet promises to create enough jobs for the million Indians entering the labour market each month.
The 108 economists and social scientists said in an open letter that Indian statistics were "under a cloud for being influenced and indeed even controlled by political considerations".
"(Any) statistics that cast an iota of doubt on the achievement of the government seem to get revised or suppressed on the basis of some questionable ideology," they said.
In 2015, the Central Statistics Office (CSO) revised economic output numbers for past years, changing the base year and showing significantly faster - and questionable - growth rates.
The letter also questioned a revised growth rate of 8.2 percent in 2016-17, "the highest in a decade!", that "seems to be at variance with the evidence marshalled by many economists".
That raised particular suspicion since this was when "demonisation" - one of Modi's biggest and most derided economic policies when 86 percent of banknotes were withdrawn - hit businesses hard.
This was followed in 2017 by the tardy rollout of a nationwide new Goods and Services Tax (GST) with which many sectors have struggled to get to grips.
The letter also noted that a major and overdue survey on employment has still not been released. Two senior statistics officials resigned in protest at the delay.
Press reports have said the study, the first of its kind since 2011-12, showed that unemployment was at its highest since the 1970s. The government says it has not been finalised.
"The national and global reputation of India's statistical bodies is at stake. More than that, statistical integrity is crucial for generating data that would feed into economic policy-making and that would make for honest and democratic political discourse," the report said.
Signatories included Sripad Motiram at the University of Massachusetts Boston, Paul Niehaus at the University of California San Diego and Abhijit Banerjee at the Massachusetts Institute of Technology (MIT).
The government was yet to comment on the letter.
