Side jobs gained in popularity in the U.S. due to wage stagnation and low wage growth that has not kept up with the rise in cost of living, with nearly a third of people with side jobs requiring them to pay expenses.[3] Nearly half of all Americans report having a side job, including 43% of full-time workers.[3] The most common reason workers take on side jobs is to obtain additional disposable income.[3] In the United Kingdom, 60 percent of students and graduates reported having a side job, and 43 percent required it to pay renting expenses.[4] Millennials are the most likely to have a side job, usually to have a financial "safety net",[5] leading to them being considered the "side hustle generation".
