Imputation Methodology for the Occupational Requirements Survey (ORS)

Leland W. Righter and Bradley D. Rhein


The Occupational Requirements Survey (ORS) is an establishment survey conducted by the Bureau of Labor Statistics (BLS) for the Social Security Administration (SSA). The survey collects information on the vocational preparation and the cognitive and physical requirements of occupations in the U.S. economy, as well as the environmental conditions in which those occupations are performed. Imputation is a multi-step process that involves determining recipients and donors, matchmaking based on a collapse pattern and nearest neighbor, and flexible imputation based on level of and retaining collected data. This paper will describe the testing that was conducted to identify the imputation method most appropriate for generating estimates for this survey. It will also describe the imputation method that is being implemented with the estimates scheduled to be released in late 2016.
