Special Purpose Files—Input/Output

This page contains links to files of input-output data for the U.S. economy for the historical years 1997, 2001, and 2002, and for the projected year 2012. Input-output data shows the flow of commodities from production through intermediate use by industries and purchases by final users. This data is developed as a set of matrices or tables for each year. The input-output tables produced by BLS are derived from input-output data initially developed by the Bureau of Economic Analysis.

Input-output data

The files for the projections, the nominal dollar historical, and the chain-weighted historical input-output tables are contained in separate ZIP files. A ZIP file utility is necessary to extract the files.

• Projected 2012 chain-weighted (1996 dollar based) input-output data with documentation
• Nominal dollar input-output data for 1997, 2001, and 2002 with documentation
• Chain-weighted (1996 dollar based) input-output data for 1997, 2001, and 2002 with documentation

Notes on the files

All data files are ASCII text. Documentation files are available as both PDF and text files. The data files are tab-delimited and contain no row or column labels. Each row of a data file is complete and contains all the columns for that row. An ASCII carriage-return character denotes the end of a given row of data. Historical tables are provided in both nominal (current) dollars and chain-weighted (1996 based) dollars. The projected tables are provided in chain-weighted dollars only. Each file contains appropriate documentation which should be consulted for specifics regarding file formats, sectoring plans, and development sources.
