Inter-industry relationships (Input/Output matrix)
This page contains links to files of input-output data for the U.S. economy for the historical years 1993-2010,
and for the projected year 2020. Input-output data show the flow of commodities from production through intermediate
use by industries and purchases by final users. These data are developed as a set of matrices or tables for each year.
The input-output tables produced by the BLS are derived from input-output data initially developed by the
Bureau of Economic Analysis.
These files are available at our FTP site.

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.
Notes on the files
All data files are ASCII text. Documentation files are available as text files.
Sector plans are also available as excel 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
(2005 based) dollars. The projected tables are provided in chain-weighted dollars only. The FTP contains appropriate documentation which should be consulted for specifics regarding file formats, sectoring plans, and development sources.
