The reliability of the survey data is examined as a supplement to the Nationwide Survey of the Occupational Safety and Health Work Force. The survey methodology is reviewed, focusing on sample selection, contact strategy, and survey instruments. A job classification scheme used to partition the survey results is developed, and a method for estimating the size of the current occupational safety and health work force is presented along with a discussion of the data limitations. The estimation and forecasting techniques are described, and avenues for further research are explored. A survey introductory letter, questionnaires concerning organization, job role and employee characteristics, and occupational safety and health titles generated by a feasibility study also are presented.
