Factor analysis

To assist users of BLS employment projections in evaluating and understanding the sources of growth and decline for individual industries or occupations, a detailed analysis of the factors entering the projections process has been carried out. The factor analysis covers the period 2018–28.

The industry employment factor analysis covers wage and salary and self-employed jobs, while the occupational employment analysis covers wage and salary jobs only. All of the tables contain employment percent changes caused by substituting a factor for the later year in place of the earlier year factor, including residual interactions among factors. In other words, each individual column answers the question, "How much would employment have changed if only this one factor had changed over the period under examination?"
