Abstract:The Commodity Flow Survey (CFS) is a joint effort by the Bureau of Transportation Statistics (BTS) and the U.S. Census Bureau, U.S. Department of Commerce. The survey is the primary source of national and state-level data on domestic freight shipments by establishments in mining, manufacturing, wholesale, auxiliaries, and selected retail and services trade industries located in the 50 states and the District of Columbia. The survey produces estimates on the type, origin and destination, value, weight, modes of transportation, distance shipped, and ton-miles of commodities shipped. The CFS is conducted every five years as part of the Economic Census. It provides a modal picture of national freight flows, and represents the only publicly available source of commodity flow data for the highway mode. The CFS was conducted in 1993, 1997, 2002, 2007 and most recently in 2012. This document describes the Public Use Microdata (PUM) File created for the 2012 Commodity Flow Survey (CFS). This user guide provides a brief description of the CFS and the differences between the CFS data used to create the published estimates and the records available in the PUM file. This document also explains how to create estimates and measures of sampling variability from the PUM file data. For a complete description of the CFS and access to the published tables, visit the CFS website at: www.census.gov/econ/cfs/. This is an experimental data product and comments from users regarding the content and usefulness of this product are appreciated.
