    (a) The Bureau of the Census classifies establishments using the 2017 North American Industry Classification System (NAICS).   

    (b) The Establishments (counts) is the total number of manufacturing establishments in the frame minus the number of ineligible establishments for post stratification. It includes those units which

reported floorspace, plus those units where floorspace was not ascertained.  To obtain the number of reporting establishments for any NAICS, divide the entry in the Approximate Enclosed Floorspace

by the corresponding entry in the Average Enclosed Floorspace.  For example, in the Total row, (11,270 million square feet) divided by (69,061.6 square feet) equals 163,188, which is the number of

reporting establishments (weighted) of the 181,126 total establishments.

    (a) The Bureau of the Census classifies establishments using the 2017 North American Industry Classification System (NAICS).   

    (b) The Establishments (counts) is the total number of manufacturing establishments in the frame minus the number of ineligible establishments for post stratification. It includes those units which

reported floorspace, plus those units where floorspace was not ascertained.  To obtain the number of reporting establishments for any NAICS, divide the entry in the Approximate Enclosed Floorspace

by the corresponding entry in the Average Enclosed Floorspace.  For example, in the Total row, (11,270 million square feet) divided by (69,061.6 square feet) equals 163,188, which is the number of

reporting establishments (weighted) of the 181,126 total establishments.    

    * Estimate less than 0.5.            

    D=Withheld to avoid disclosing data for individual establishments.            

    Q=Withheld because Relative Standard Error is greater than 50 percent.

    X=Not defined because RSE corresponds to a data table value of zero.            

    NA=Not available.            

    Notes: Totals may not equal sum of components because of independent rounding.
