The share of workers engaged in gig work has grown over time, though relatively modestly, from about 10 percent in 2005 to almost 16 percent in 2015, according to the report. Popular notions would say that this has to do with technological advancements. But the McKinsey report suggests differently. Among these gig workers, only 15 percent, a relatively small fraction, have earned income using a digital platform. “Despite their extensive media coverage, digital “on-demand” or “sharing economy” platforms such as Uber, Lyft, TaskRabbit, Upwork, Freelancer.com, Thumbtack, Airbnb, and the like facilitate only a small fraction of independent work today,” the report states.
