A closer look at household income in Illinois: how it ranks among the states, what it takes to reach the top 25% or 10%, how earnings change with age, and how far apart its 102 counties are.
Illinois's median household income is $83,390, 18th of 51 states and DC and 3% above the national median of $80,734. Prices for housing and everyday costs also differ by state, and these figures don't adjust for them.
Illinois's top-quarter threshold of about $145,900 compares with $141,925 across the country. Households earning over $200,000 make up 14% of the state, compared with a 13% national share.
Comparing the two Census products: $83,211 in the 2024 one-year estimate, $83,390 in the 2020–2024 five-year estimate (0%).
About 14% of Illinois households report income of $200,000 or more, the Census's top published bracket. By household income, the top 25% start at about $145,900, and the top 10% sit above $200,000. The table marks lines that fall above $200,000 rather than guessing their value: the Census groups everyone above that amount together, so the exact top-5% and top-1% cutoffs can't be read from this data.
Another way to read it: a household earning exactly the national median, $80,734, would rank around the top 51% in Illinois — below the state's own midpoint.
Comparing the two lines gives a ratio of 1.77 (top quarter over median), about the same as the 1.77 seen nationwide.

Earnings per worker in Illinois peak at 45–54, with a median of $62,968, compared with $48,881 for workers aged 25–34. On average the state runs +4% relative to the US at each age, with the largest difference among workers aged 35–44. These figures are personal earnings (wages plus self-employment) from Census microdata, so they're lower than household income, which can combine several earners.
