The U.S. Census Bureau and the Local Employment Dynamics (LED) Partnership in collaboration with the Council for Community and Economic Research (C2ER) and the Labor Market Institute (LMI), welcomes James Spletzer and Keith Bailey as they present, “A New Measure of Multiple Jobholders in the U.S. Economy.” This presentation looks at measures of multiple jobholding using the U.S. Census Bureau's Longitudinal Employer-Household Dynamics data. This new series shows that 7.8 percent of persons in the U.S. are multiple jobholders, and the numbers have been trending upward during the past twenty years. The data also show that earnings from secondary jobs are, on average, 27.8 percent of a multiple jobholder's total quarterly earnings. Multiple jobholding occurs at all levels of earnings, with both higher- and lower-earnings multiple jobholders earning more than 25 percent of their total earnings from multiple jobs. These new statistics tell us that multiple jobholding is more important in the U.S. economy than realized.
