WHAT THE STATE DISTRIBUTION SAYSWithin Illinois, the relevant dispersion is among 24 current published direct-evidence ZIP reports, not a claim about every rental location. The June 2026 Zillow ZORI observed asking-rent index ranges from $1,113 in 61701 (Bloomington) to $2,801 in 60201 (Evanston): a $1,688 spread around a $1,819.50 median. That range makes a single statewide rent shorthand unhelpful for a renter comparing search areas. The operational question is not simply where the index is lowest, but how a local current asking-rent signal, local income context, historic burden, and the chosen bedroom benchmark line up for the household and unit under consideration. It is a comparison framework rather than an answer about a household’s specific budget, lease, or unit choice.
Affordability and renter burden are related but not interchangeable. Pairing current ZORI with ACS ZCTA median household income produces an asking-rent-to-income ratio from 18.8% in 60540 to 52.9% in 61820; it is a current asking-rent-to-area-income screen, not a count of households in distress. In contrast, the ACS 2024 five-year estimate of renter households spending 30% or more of income on gross rent spans 34.5% in 60647 to 59.8% in 60201. The first comparison connects a current index to an area-income estimate, whereas the second records estimated household burden using gross rent. These ACS figures describe ZCTAs—statistical areas that are not identical to USPS delivery ZIPs—and reflect survey estimates rather than current asking rents.
Rent momentum should also be separated from volatility. In the direct monthly ZORI series, one-year growth runs from a 0.8% decline to a 10.9% increase, against a 5.6% median. Annualized volatility spans 1.4% to 4.7%, with a 3.2% median. A ZIP’s net change over the specified year can therefore be high without being the most variable monthly path, and a volatile path need not denote the strongest annual increase. Growth measures end-to-end change; volatility summarizes month-to-month variation in that same observed asking-rent index. Neither measure establishes a future rent path or a property-level pricing outcome.
HUD’s FY2026 two-bedroom FMR/SAFMR is an administrative bedroom standard, not an asking-rent observation. Comparing ZORI with it yields asking-versus-HUD ratios from 85.5% to 129.2%, with a 108.2% median among published reports. A ratio above or below parity only positions the two measures against each other; it does not establish that a particular two-bedroom is priced above or below its market asking rent. The distribution is limited to current published direct-evidence ZIP reports, and ZORI, ACS, and HUD data cannot identify a property’s actual rent, availability, exact bedroom configuration, lease terms, or condition. Verify the specific unit and applicable program rules separately.
