What is the household income near Madison car washes?
In a chain-consolidated market like Madison, ZIP-level income tells you more about where chains chose to deploy capital than about how customers actually rate the wash. Rollups tend to anchor expansion in the $75K–$150K AGI band; below that range, supply is thinner.
Pearson r between ZIP income and Google rating across 183 qualifying locations: 0.05 — effectively zero. Operating quality dominates over neighborhood income. Scatter mean: $95K AGI/return, 4.14★.

} About this analysis
Car wash inventory for the Madison, WI CBSA is determined by point-in-polygon test against the official US Census county boundaries (TIGER/Line, 2024) for the 4 counties that make up the MSA. Each location was verified to fall inside one of those county polygons; lat/lng comes from Google Maps metadata.
Operating-quality signals are derived from 5,878 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.
