The resulting report, Independent work: Choice, necessity, and the gig economy, finds that up to 162 million people in Europe and the United States—or 20 to 30 percent of the working-age population—engage in some form of independent work. While demographically diverse, independent workers largely fit into four segments (exhibit): free agents, who actively choose independent work and derive their primary income from it; casual earners, who use independent work for supplemental income and do so by choice; reluctants, who make their primary living from independent work but would prefer traditional jobs; and the financially strapped, who do supplemental independent work out of necessity.
