The BLS projection process does not end at publication. BLS is constantly working to improve the accuracy of the projections. To ensure that the projections are reliable and of the highest quality, BLS typically evaluates its projections after the target years have passed. Projections of the labor force, industry employment, and occupational employment are evaluated using metrics that provide measures of accuracy. These metrics were developed from a review of methods used by BLS and other agencies in evaluating projections.
The evaluations benefit BLS and external users. Identifying sources of errors helps BLS improve the models used in developing the employment projections. And publishing the results allows users to gauge the accuracy of statements about future economic conditions, industry activity, and employment growth.
