} About this analysis
Car wash inventory for Northbrook, IL is sourced from the WashIndex national car-wash place index, filtered to places whose Google-Maps-reported city matches Northbrook, and further restricted to places whose format the WashIndex LLM classifier identified as a car wash (excluding dealerships, gas stations, and other auto-related businesses that don't primarily operate a car wash). Inclusion in the parent Chicago MSA dataset is established by point-in-polygon against the official US Census county boundaries (TIGER/Line, 2024).
Operating-quality signals are derived from 239 customer reviews processed through WashIndex's 55-field LLM extraction pipeline. Format classification comes from a separate per-location website-reading classifier. ZIP-level income data is from the IRS Statistics of Income (tax year 2022) — mean Adjusted Gross Income per tax return, which is directionally aligned with ACS median household income but available without authentication.
