Census 2020 Make Sure Illinois Counts

Why a complete count is important to Illinois

According to the Illinois Complete Count Commission, Illinois was undercounted in the 2010 Census with only 76% participation rate.  The ramifications for undercounting in Illinois in the 2020 Census include:

  • Loss of one and possibly two seats in the House of Representatives.
  • Loss of one and possibly two Electoral College votes.
  • Forfeiture of billions of dollars of federal assistance for programs that aid children, veterans, senior citizens, middle and low income families, schools, healthcare facilities, and infrastructure.
