Methodology

Coverage. All car washes located in South Dakota metropolitan statistical areas (Census 2023 CBSA delineation), tracked across 2 metros. Customer reviews are ingested from Google and processed through WashIndex's structured LLM extraction pipeline across 55 dimensions.

State-level aggregates. Location counts, review counts, and rating averages are review-weighted sums across the state's MSAs. Damage rate, cancellation rate, and aspect scores are weighted by scored-review volume so high-review-count markets pull more weight than thin ones. National baselines are computed the same way across all 50 states.

What's drillable. Click any chain to see its full per-chain operator profile (including per-state breakdowns); click any metro to drill into MSA-level format mix, county data, ZIP-level income overlays, and per-location records.
