Detailed data are available in the 2002 Benchmark Input-Output table for industry and commodity output, final uses by commodity, value added by industry, and intermediate purchases of commodities by industries. The Benchmark table is released at the sector, summary, and detail level. These generally correspond to 2-, 4-, and 6-digit NAICS codes respectively. More detailed industry data is available through the economic census, which is available via the Census Bureau’s web page at http://www.census.gov/econ/census02/. Specific company data are proprietary and are not reported by BEA or the Census Bureau.
