Today we’ll try to better understand moonlighting—that is, holding multiple jobs. The Bureau of Labor Statistics records the number of multiple jobholders, and FRED has the data all the way back to 1994. What can we learn from the graph?

Most multiple jobholders hold a full-time plus a part-time job (blue line in the graph), and this group now makes up about 3% of the working population in the U.S. The percentage of workers with this particular work arrangement has declined since at least 1994, when it was over 3.5%.

Those in the next-largest group hold two part-time jobs (red line). The percentage of workers with this arrangement is significantly lower than the first group—a little less than 1.5% of all employees—and has been quite stable over time.

Finally there’s a small group of workers with two full-time jobs (green line), which accounts for about 0.25% of workers. The percentage for this group has also been quite stable since 1994.

We can also see that recessions don’t seem to have a significant impact on these groups of workers with multiple jobs.

How this graph was created: Search for and select the monthly series “Multiple Jobholders, Primary Job Full Time, Secondary Job Part Time.” From the “Edit Graph” panel, use the “Edit Line 1” tab’s “Customize data” section to search for and add an additional series: “All Employees: Total Nonfarm Payrolls” (not seasonally adjusted option). Then type “a/b*100” into the formula box and click “Apply.” Repeat this process for lines two and three, with “Multiple Jobholders, Primary and Secondary Jobs Both Part Time” for line two and “Multiple Jobholders, Primary and Secondary Jobs Both Full time” for line three. All series should be not seasonally adjusted. Use the “Format” tab to select alternative colors for the lines.
