How were these city records selected?
CarrierTrail selected cities with at least 100 census records and ten eligible company examples and keeps that city list stable. Counts use records present in the official FMCSA census data with a U.S. physical address and the exact reported state/city combination. City text is compared without letter case; spelling variants are not combined. The sample sorts eligible records by a hash of USDOT, then USDOT, and takes up to 20. These 615 records make up 4.0% of the 15,416 records reporting a physical location in Wyoming in this snapshot.
