Footnotes:

  1. Some payroll and sales data for small single establishment companies with up to 20 employees (cutoff varied by industry) were obtained from administrative records of other government agencies rather than from census report forms. These data were then used in conjunction with industry averages to estimate statistics for these small establishments. This technique was also used for a small number of other establishments whose reports were not received at the time data were tabulated. The following symbols are shown where estimated data based on administrative record data account for 10 percent or more of the figures shown:
    • 1: 10 to 19 percent
    • 2: 20 to 29 percent
    • 3: 30 to 39 percent
    • 4: 40 to 49 percent
    • 5: 50 to 59 percent
    • 6: 60 to 69 percent
    • 7: 70 to 79 percent
    • 8: 80 to 89 percent
    • 9: 90 percent or more
  2. Industries with 500 employees or more are shown. Some statistics are withheld to avoid disclosing data for individual companies. If employment is 500 or more, number of establishments is shown and employment size range is indicated by one of the following symbols:
    • a: 0 to 19 employees
    • b: 20 to 99 employees
    • c: 100 to 249 employees
    • e: 250 to 499 employees
    • f: 500 to 999 employees
    • g: 1,000 to 2,499 employees
    • h: 2,500 to 4,999 employees
    • i: 5,000 to 9,999 employees
    • j: 10,000 to 24,999 employees
    • k: 25,000 to 49,999 employees
    • l: 50,000 to 99,999 employees
    • m: 100,000 employees or more
