Illinois is the sixth most populous U.S. state with 12.5 million residents and was one of six states that had undercounts of its population, according to the Census Bureau. In his correction request, Gov. JB Pritzker didn’t specify how many people he believes were missed but cited the bureau’s estimate of almost 2% of the population. Among the omissions were residents in nursing homes, dorms, homeless shelters, residential treatment facilities and jails, Pritzker said in one of two letters submitted to the Census Bureau.

“Because of an inaccurate census count, the state of Illinois received inadequate federal funding for Medicare, affordable housing, homeland security and a number of other essential programs,” said Alex Gough, a spokesperson for the governor’s office.
