· range 3.2–3.4
Ancient Tree spans 3 census tracts of Northbrook, IL and houses 17,600 people. The Eviction Risk Score is 3.3/10, in the Lower tier. Against a Northbrook baseline of 30.5%, 51% of renters here cross the 30%-of-income line.
Average gross rent is $1,471, 40% below the Northbrook average of $2,463. Pulling the other way is economic stress, at 1.2/10.
The voucher gap is 16.0%: households holding assistance that local rents will not absorb, which shows up as churn rather than arrears. 11% are severely burdened, paying half their income or more in rent. That cohort has no absorption capacity for an unexpected bill, and it is where non-payment filings originate.
Filings are well documented here: 204 across 3 observed tracts. Food insecurity affects 6.6% of adults, 11.2 points below the national rate. On the high side is rent-regulation exposure at 7.1/10.
Filing activity peaked in 2013 at 15.9% of renter households. 4.5% of adults carry no health insurance against 11.3% nationally, a common route into sudden unpayable debt. The most recent observed rate, 1.3% in 2015, is well off that peak.
That places it #1 of 5 neighborhoods in Northbrook.
With little internal variation, 3.3/10 is a fair proxy for any address inside the boundary. Scores move when the ACS release, the court-record feed, or the statute ledger behind them moves.
