Illinois's statewide retirement-income exemption applies here, and is genuinely relevant
Illinois's real, no-threshold exemption of Social Security, pension, and 401(k)/IRA income (illinois.js) applies fully in Mattoon, and is genuinely more relevant here than in a typical college town given Mattoon's real, sourced older population (19.3% 65-plus).
Illinois's real, current, escalating tornado/derecho insurance trend applies statewide
Mattoon shares Illinois's real, current 2026 severe-weather profile -- a record 202+ confirmed tornadoes statewide and the August 11, 2026 derecho -- and the real, sourced statewide homeowners-insurance premium increases tied to that trend (illinois.js). No Mattoon-specific premium figure was independently verified this pass.
