Abstract:
The Technical Complementation Project (TCP) in Survey Sampling is organized to perform a statistical assessment of the quality of statistics generated by the five surveys conducted by the Bureau of Labor and Employment Statistics (BLES): (1) Occupational Wages Survey (OWS); (2) Occupational Injuries Survey (OIS); (3) Survey of Specific Group of Workers (SSGW); (4) Industrial Relations in the Workplace Survey (IRWS); and (5) Employees’ Hours and Earnings Survey (EHES). All five surveys are establishment surveys which can be administered either through personal interview or by mail. Further, these five surveys cover establishments all over the country that cuts across all industries and uses the National Statistics Office’s 1992 List of Establishments as the sampling frame. They all follow a stratified sampling design with region industrial classification (PSIC) as domains and average total employment as strata. Assessment results indicate that nonresponse is a major problem in all five surveys considered in the study. BLES is recommended to explore procedures for correcting estimates, including imputation techniques.
