Commodity Flow Survey

PURPOSE

The 2007 Commodity Flow Survey (CFS) is undertaken through a partnership between the Bureau of the Census, U.S. Department of Commerce, and the Bureau of Transportation Statistics, U.S. Department of Transportation. This survey produces data on the movement of goods in the United States. The data from the CFS are used by public policy analysts and for transportation planning and decision-making to assess the demand for transportation facilities and services, energy use, and safety risk and environmental concerns.

COVERAGE

The 2007 CFS covers business establishments in mining, manufacturing, wholesale trade, and selected retail industries. The survey also covers selected auxiliary establishments (e.g., warehouses) of in-scope multi-unit and retail companies. The survey coverage excludes establishments classified as farms, forestry, fisheries, governments, construction, transportation, foreign establishments, services, and most establishments in retail.

CONTENT

The CFS captures data on shipments originating from selected types of business establishments located in the 50 states and the District of Columbia. We request that the respondent provide the following information about their establishment’s shipments: 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, or hazardous material. 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, we also ask the respondent to provide the mode of export and the foreign destination city and country. For hazardous materials shipments, we ask for the corresponding UN/NA code.

FREQUENCY

The survey was initiated for 1993. Beginning with 1997, we plan to conduct the survey every 5 years for years ending in "2" and "7." Commodity surveys were conducted between 1963 and 1983, but data for 1983 were not published. No data were collected for 1987.

METHODS

The 2007 CFS consists of a sample of 50,000 establishments chosen based on geographic location and industry. Each establishment selected into the CFS sample is mailed a questionnaire for each of its four reporting weeks. For the CFS each sampled establishment was asked to report on a sample of individual shipments during a one week period in each calendar quarter.

PRODUCTS

Information is available in printed reports and electronic form for the 1997 Commodity Flow Survey. The Preliminary 2002 CFS report was released in December 2003, with estimates at the national level, for tons, miles, ton-miles and value by mode of transportation (including intermodal combinations), shipment distance, commodity, and weight. In the Fall of 2004, the final data will become available. The geographical breakdowns will include U.S., Census Divisions and Regions, individual states, with selected sub-state categories.
