In 2013, 6.8 million workers in the United States held more than one job. Twenty years before, the figure was 7.5 million, although the total number of workers with a job was lower by 15.9 million. The multiple-jobholding rate—the proportion of multiple jobholders among all workers—rose from 6.2 percent in 1994 to a high of 6.8 percent during the summer of 1995. It has declined steadily since then and was at 5.0 percent by the end of 2013.
Multiple jobholding has become less common for both men and women, although the downward trend has been sharper among men. Multiple-jobholding rates among women held fairly steady between the 2001 recession and the 2007–2009 recession.
