Where the customers (and the spend) are.
Each ZIP in the Pontiac MSA has been joined to IRS Statistics-of-Income data (tax year 2022, mean Adjusted Gross Income per return as the income proxy) and to the per-location Google rating dataset. The scatter below plots every car wash with at least 10 reviews against its ZIP-level income, with each dot colored by format and sized by review volume.
Across 8 qualifying locations the simple Pearson correlation between ZIP income and Google rating is -0.73 — a mild negative correlation. Higher-income ZIPs in this MSA host slightly lower-rated car washes on average, which is unusual and worth investigating at the operator level. The mean-of-scatter location sits at $38K AGI/return and 4.33★.

About this analysis
Car wash inventory for Pontiac, MI is sourced from the WashIndex national car-wash place index, filtered to places whose Google-Maps-reported city matches Pontiac, 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 Detroit MSA dataset is established by point-in-polygon against the official US Census county boundaries (TIGER/Line, 2024).
Operating-quality signals are derived from 138 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.
