(a) The North American Industry Classification System (NAICS) has replaced
the Standard Industrial Classification (SIC) system.
(b) The 'Establishments (counts)' column 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' column by the corresponding
entry in the 'Average Enclosed Floorspace' column.  For example, in the 'Total' row,
(12,836 million sq ft) divided by (71,257.0 sq ft) equals 180,137, which is the number of reporting
establishments (weighted) of the 226,813 total establishments.
NF=No applicable RSE row/column factor.
* Estimate less than 0.5.
W=Withheld to avoid disclosing data for individual establishments.
Q=Withheld because Relative Standard Error is greater than 50 percent.
NA=Not available.
Notes:  To obtain the RSE percentage for any table cell, multiply the cell's
corresponding RSE column and RSE row factors.   Totals may not equal sum of
components because of independent rounding.
