1The sampling frame was developed from state unemployment insurance reports and is based on the 2012
North American Industry Classification System (NAICS). With some minor exceptions, an establishment is a
single economic unit that engages in one, or predominantly one, type of economic activity. For private industry,
the establishment is usually at a single physical location such as a mine, factory, office, or store; if a sampled
establishment is owned by a larger entity with many locations, only the employment and characteristics of the
establishment selected for the sample are considered for the survey. For state and local governments, an
establishment can include more than one physical location, such as a school district or a police department.
2Establishments that provided data at the initial interview.
3Establishments that did not provide data at the initial interview. Data for establishments not responding at
the time of update interviews are imputed. Detailed information on nonresponse adjustment and imputation can
be found in BLS Handbook of Methods, Chapter 8, “National Compensation Measures,” Bureau of Labor
Statistics, on the Internet at www.bls.gov/opub/hom/pdf/homch8.pdf.
