Nonemployer Statistics provide data for establishments without payroll (i.e., no paid employees) along with data for establishments with payroll and for all establishments by kind of business for the United States and States. All other tabulations from the Census of Transportation, Communications, and Utilities, including all Geographic Area Series data, do not include nonemployers. Nonemployers account for 10 to 12 percent of revenues in SIC major groups 41, 42 and 47, but only 1 percent or less of revenues among other major groups covered in the census. These data are provided on a separate CD-ROM (1992 Economic Census CD-ROM Volume 4, Nonemployer Statistics) sent to all subscribers to CD-ROM volume 1, Report Series; the Nonemployer Statistics (Volume 4) disc is also available for purchase separately.
