The University of Illinois Flash Index rose to 96.3 from its 95.9 level in December. The report said January results suggest only modest gains for the economy because of the resurgence of the virus and the mandated closures. Author Fred Giertz says the index dropped to around 93 last May during the height of the pandemic. Giertz says all three components of tax receipts used in his analysis, personal income, sales and corporate taxes were higher in January. The Flash Index has remained below 100 since last March, showing Illinois’ economy is not growing.
