The Census Bureau released its final numbers from 2002 of their survey of private businesses (better late than never...after all, it is the federal government.....).
Here is a summary:
There were 23 million nonfarm U.S. businesses in 2002, employing 110.8 million persons and generating $22.6 trillion in business revenues. Firms with paid employees accounted for 5.5 million or 24.0 percent of these businesses and $21.8 trillion or 96.6 percent of their receipts....There were 98,352 firms with 100 employees or more which accounted for $16.0 trillion in gross receipts (73.5 percent of the total receipts of all employer firms).
For more detail you can find the summary here and the full report here (all 1579 pages!!!).
