Commodity Flow Survey (CFS)

Wednesday, September 15, 2021

The CFS provides a comprehensive multimodal picture of national freight flows. Data include the type of commodities shipped, origin and destination, value and weight, and mode of transport for approximately 100,000 shippers. CFS is also the only publicly available source of this data for the highway mode.


To learn more about the CFS, watch the video below.


Commodity Flow Survey Workshop

The latest CFS workshop, organized by the Transportation Research Board (TRB), was held in September 2020.  The workshop was an opportunity for data producers and data users to work together to find more efficient ways to align freight data products, answer freight data questions, share information and knowledge, and identify emerging issues that are important for understanding freight movements.

The post-workshop circular can be found at the link below.  Please direct any questions you may have to cfs@dot.gov.

Commodity Flow Survey Overview

The Commodity Flow Survey (CFS), a component of the Economic Census, is conducted every five years by the U.S. Census Bureau in partnership with the U.S. Department of Transportation’s Bureau of Transportation Statistics. The 2017 CFS is the sixth survey in the program that began in 1993. The CFS is a shipper survey of approximately 100,000 establishments from the industries of mining, manufacturing, wholesale trade, auxiliaries (i.e. warehouses and distribution centers), and select retail and service trade industries that ship commodities. Data requested by the CFS includes the type of commodities shipped, their origin and destination, their value and weight, and mode(s) of transport. The CFS provides a comprehensive multimodal picture of national freight flows and represents the only publicly available source of data for the highway mode. Results from the CFS are used to analyze trends in the movement of goods, mapping spatial patterns of commodity and vehicle flows, forecasting demands for the movement of goods, and for guiding management and investment decisions on transportation infrastructure.


Announcement!

We are pleased to announce that it is now easier for researchers to access Commodity Flow Survey (CFS) microdata in the Federal Statistical Research Data Centers (FSRDC). 
 
Title 13 versions of the 2012 and 2017 CFS data will soon be available for researchers to request in FSRDCs. Researchers can now access CFS microdata without the lengthy IRS approval process.
 
Researchers still need to request FSRDC access and receive Special Sworn Status (SSS) clearance. The project must provide a benefit back to the Census Bureau and estimates must have Disclosure Review Board approval before being released. Lastly, the microdata cannot be used for regulatory purposes. More details on the process of applying for FSRDC access and SSS clearance can be found at https://www.census.gov/about/adrm/fsrdc/apply-for-access.html.

The Commodity Flows Survey (CFS) captures samples of shipments originating from selected types of business establishments located in the 50 states and the District of Columbia. The dataset includes origin establishment information, domestic destination or port of exit, commodity, value, weight, mode(s) of transportation, the date on which the shipment was made, and an indication of whether the shipment was an export, hazardous material, or temperature controlled. For shipments that include more than one commodity, respondents are instructed to report the commodity that makes up the greatest percentage of the shipment's weight. For exports, the respondent is asked to provide the mode of export and the foreign destination city and country. For hazardous materials shipments, the corresponding UN/NA code is collected.
 
These versions of CFS data have been altered to remove Title 26 (IRS) data. These alterations impact roughly 5% of the shipment-level data and 10% of the establishment-level information.
