================================================================

The data files contained in the ZIP files include only cell data.
There are no labels, descriptions, code numbers, or summation
values in these data files.

Hence, one needs to look at the sectoring plans to obtain the
industry and final demand codes and descriptions.  See files 
"sect_industry_x195.xls" files for industry and commodity sectors
and "sect_final_demand_x190.xls" files for the final demand sectors.

Since there are no labels, the "sect_industry_stubs" file
version can be attached to the right side of a spreadsheet if
one wants to attach industry or commodity labels on to a
spreadsheet.   

The file names begin with either NOMINAL for nominal (current)
dollar historical data, REAL for chain weighted real dollar
historical data, or PROJECT for projected 2020 data.  Input-
output projections are only made in real dollars.

This is followed by the name of the I-O table and the table year. 

USE    -  196 rows and 196 columns of data (row 196 is value
          added; column 196 is final demand; the rest are
          the intermediate cells)
MAKE   -  195 rows and 195 columns of data
FD     -  195 commodity rows and 190 detailed final demand
          sectors of data
FDAGG  -  195 commodity rows and 12 final categories of data
          aggregated from the 190 sectors mentioned above


For 1993 through 2010, and projected 2020, the OUPUT tables
shown below can be replicated by adding either the USE or
MAKE tables above.  Like the USE and MAKE tables above,
all file names shown below begin with either NOMINAL, REAL,
or PROJECT.

OUTPUT_IND9310 - 1993-2010 historical industry output time
                 series (columns 1 through 18 respectively)
OUTPUT_COM9310 - 1993-2010 historical commodity output time
                 series (columns 1 through 18 respectively)
OUTPUT_2020    - Projected 2020 commodity output in column 1
                 and industry output in column 2
