1Plans closed to new workers or plans that cease accruals for some or all plan participants.
2Includes workers in the private nonfarm economy except those in private households, and workers in the
public sector, except the federal government. See Technical Note for further explanation.
3The length of time is calculated based on the year the plan was modified. For example, plans frozen
after January 2015 are included in the "1 year" column. Those frozen between 2011 and 2014 are included in
the "2 to 5 years" column and plans frozen before 2011 are included in the "Greater than 5 years" column.
4Surveyed 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 wage data for March 2016.

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
www.bls.gov/ncs/ebs/glossary20152016.htm.
