About 98% of these governments fall on the 2028 date, but the 53 large suburban townships, with 33 between 50,000 and 99,999 and 20 between 100,000 and 199,999, are on the earlier one. The counts use 2021 estimates, and ADA.gov says most governments find their population in 2020 Census data (ADA.gov (opens in a new tab)). (U.S. Census Bureau (opens in a new tab))
The interim final rule took effect on publication, and comments closed June 22, 2026 (Federal Register (opens in a new tab)). Illinois' own Information Technology Accessibility Act covers state entities and says the term "does not include units of local government" (30 ILCS 587/10 (opens in a new tab)).
