The gig economy remains fairly small — for now. Both RAND and JPMorgan Chase find that only about 0.5 percent of Americans earn labor income through gig platforms. However, this form of work is growing quickly. The JPMorgan analysts also reported that the number of Americans working in the gig economy grew by more than a factor of 50 between 2012 and 2015. The most prominent gig economy company — Uber — has quadrupled in size in less than two years. Uber grew from 160,000 active driver-partners in December 2014 to over 680,000 in September 2016.
