About this analysis
Car wash inventory for the Milwaukee-Waukesha, 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 20,327 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.
See our full methodology
for the extraction pipeline, validation samples, and aggregation logic. Term definitions in the glossary.
The free WashIndex platform shows every Milwaukee car wash on an interactive map, with the same review-derived
signals and demographic overlays that power this analysis. Filter by format, drive-time, or operator and compare any
location head-to-head with its true competitive set.
