With a median household income of $57,544 and a median home value of $199,700, local labor rates come out below the national middle in our model.
Champaign County had 19 hail days and 38 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 inches across.
