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,

(11,100 million sq ft) divided by (82,311.6 sq ft) equals 134,853, which is the number of reporting

establishments (weighted) of the 170,168 total establishments.

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