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 projection process
has been carried out. This factor analyses covers the period 2010-20.
In addition, an occupational table is provided for 2010-20, covering 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?"
These files are available at our FTP site.
