A statistic gathered by the U.S. Bureau of Labor Statistics, which represents the payroll data for the majority of the United States with the exception of a few categories of employees. The employees that are not included in this calculation include government employees, nonprofit employees, individuals who work within a private household, and farm employees. Once these categories are removed, the data represents about 80% of United States employees, and provides monthly information about salary which is used as an indicator of the health of the economy.
