The U.S. Census Bureau, with the Bureau of Transportation Statistics (BTS), has released an experimental data product providing additional geographic granularity to 2017 Commodity Flow Survey (CFS) estimates. These Subarea estimates divide the existing 132 CFS Areas into 329 Subareas. 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.
To capture both the incoming and the outgoing shipment activity from a state/metropolitan area, two tables are provided -- one lists the CFS Subareas as shipment origins and the second lists the CFS Subareas as shipment destinations.
This is the first time these experimental data have been made available publicly on the Census Bureau webpage and comments from data users about the content and usefulness of these data are appreciated. Provide feedback to: ERD.CFS@census.gov

Items for Dissemination:
2017 CFS Subarea estimates by origin (Table O) -- Estimates of the total value, total weight, total ton-miles, average miles per shipment, and total number of shipments, for truck or ground parcel shipments. The areas for which the estimates are made are: origin (CFS Subarea) x destination (Census Region, state, CFS Area, or CFS Subarea) x commodity group.
2017 CFS Subarea estimates by destination (Table D) -- Estimates of the total value, total weight, total ton-miles, average miles per shipment, and total number of shipments, for truck or ground parcel shipments. The areas for which the estimates are made are: origin (Census Region, state, CFS Area, or CFS Subarea) x destination (CFS Subarea) x commodity group.
