The concept of the "gig economy" clearly captures something real, but it can be hard to measure define in the statistical sense that brings joy to my heart. For example, it clearly refers to those who drive for Uber and Lyft. But does it refer more broadly to all workers with "alternative work arrangements," who are hired for a short-term job with no serious expectation that it will become a longer-term employment connection? Does it cover people who obtain jobs through a temp agency and work for a series of employers, for example?
