Flerarbetande amerikaner

Såg att Johan Norberg argumenterade om amerikaner med fler än en inkomstkälla, angående hans tidigare artikel på temat, och letade upp uppdaterad statistik - från U.S Bureau of Labor Statistics Multiple jobholding during the 2000s (pdf):

The incidence of multiple jobholding generally increases as workers achieve higher levels of education. (See table 2 and chart 3.) Among workers age 25 and older, those with less than a high school diploma had a low multiple jobholding rate (2.4 percent). The rate was much higher (7.0 percent) for workers with an advanced degree, especially those with a master's degree or a doctoral degree.
