A report on unemployment prepared by the National Sample Survey Office's (NSSO's) periodic labour force survey, has not been officially released by the government. According to "Business Today", this report is the "first comprehensive survey on employment conducted by a government agency after Prime Minister Narendra Modi announced demonetisation move in November 2016". According to this report, the 2017–2018 "usual status" unemployment rate in India at 6.1%, a four-decade high, possibly caused by the 2016 demonetisation of large banknotes intended to curb the informal untaxed economy.
