Around one-quarter of Americans (28%) say they have not used any major shared or on-demand platforms, and many are wholly unfamiliar with the tools and vocabulary of the new digital economy. For instance, 15% of Americans have used ride-hailing apps like Uber or Lyft, but twice as many have never heard of these apps before. Similarly, 11% of Americans have used home-sharing platforms like Airbnb or VRBO, but roughly half have never heard of home-sharing sites.
