This paper presents survey measures of informal "gig" work in the United States along both the extensive and intensive margins. Focusing on labor-intensive activities, the total amount of gig work performed by U.S. household heads in 2015 was equivalent to 3.77 million full-time jobs, of which 20 percent came from online work. We also find that this nonstandard work is partly hidden: over 15 percent of non-retired gig workers would get classified as not in the labor force, 5 percent would get classified as unemployed, and the full-time employment rate would increase significantly if informal hours are fully counted.
