Commodity Flow Survey

Subarea: The U.S. Census Bureau, together with the Bureau of Transportation Statistics (BTS), has released an experimental data product providing additional geographic granularity to existing Commodity Flow Survey (CFS) estimates. These Subarea estimates divide the existing 132 CFS Areas into 329 Subareas such that each Subarea consists of at least one county and – in general – at least 10,000 CFS shipments. Data are available for origin by destination by commodity group at one mode of transportation – combined truck and ground parcel. Finer geographic detail is provided for origins and destinations that are geographically near each other. For rarer, long-distance shipments, paired geographies are aggregated at either the origin or the destination.
