1Surveyed occupations are classified into wage
categories based on the average wage for the occupation,
which may include workers with earnings both above and
below the threshold.  The categories were formed using
percentile estimates generated using data from the
National Compensation Survey publication, "Employer
Costs for Employee& nbsp;Compensation - March 2013."


NOTE: Dash indicates no workers in this category or data
did not meet publication criteria. For definitions of major
plans, key provisions, and related terms, see the
"Glossary of Employee Benefit Terms" at
