} About this analysis
Car wash inventory for the Boise City, ID CBSA is determined by point-in-polygon test against the official US Census county boundaries (TIGER/Line, 2024) for the 5 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 9,937 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.
