  1 Industry sectors are determined by the 2007 North American Industry Classification System (NAICS).
  2 The relative standard error (RSE) is the standard error expressed as a percent of the estimate. It can be used to calculate a "confidence interval" around a sample estimate.
For more information about RSEs, see appendix A.
  3 Earnings are the straight-time hourly wages or salaries paid to employees. They include incentive pay, cost-of-living adjustments, and hazard pay. Excluded are premium pay
for overtime, vacations, and holidays; nonproduction bonuses; and tips. The mean is computed by totaling the pay of all workers and dividing by the number of workers, weighed by
hours.
  4 A classification system including about 800 individual occupations is used to cover all workers in the civilian economy. See appendix B for more information.
  5 The relative standard error (RSE) is the standard error expressed as a percent of the estimate. It can be used to calculate a "confidence interval" around a sample estimate.
For more information about RSEs, see appendix A.
