· range 3–3
Thornley maps to a single census tract in St. Charles, IL and houses 4,496 people. That produces an Eviction Risk Score of 3/10, Lower tier. The severe-burden share is 53%. Those renters are past the 50% mark, and they miss rent for reasons that have nothing to do with willingness to pay.
69% of renters here are cost-burdened at the 30% threshold, well clear of the St. Charles rate of 33.3%. The main counterweight is economic stress, at 1.3/10. Average gross rent is $1,476, 19% below the St. Charles average of $1,819.
Food insecurity affects 6.1% of adults, 11.7 points below the national rate. 3.6% of adults report being unable to pay a utility bill, below a 9.2% national figure. Utility arrears usually lead rent arrears by a month or two. That places it #2 of 4 neighborhoods in St. Charles.
Only 14% of units are renter-occupied. Rental comparables are thin here; price renewals off the nearest genuine rental sub-market rather than off surrounding sale prices. For a like-for-like read, Red Gate Ridge and Lake Charlotte score within a fraction of it. Rent takes 11% of average household income, comfortably inside the 30% line and unusually low for a rental sub-market.
Poverty sits at 5%, low enough that arrears here usually reflect a specific shock rather than a structural income gap.
Because the boundary contains one tract, 3/10 is simultaneously the area figure and the address-level figure. The number is rebuilt whenever its ACS, court-record, or statutory inputs change.
