Some 15 per cent of Americans have used a ride-hailing service such as Uber or Lyft and 11 percent have booked a stay with an online service such as Airbnb or HomeAway, according to the Pew Research Center survey.
When adding those using other on-demand services such as grocery delivery or errand applications, the total percentage using any of the services jumped to 72 percent, Pew found.
The remaining 28 per cent have not used any major sharing or on-demand platforms, and many are unfamiliar with these services, according to the poll of 4,787 Americans.
"Some Americans have deeply integrated these platforms into their day-to-day lives -- but a larger number exist on the fringes of the sharing and on-demand economy."

The survey focused on 11 "sharing" or on-demand services ranging from the popular ride-sharing service Uber to platforms such as Instacart for grocery delivery and TaskRabbit for errands and personal services.
The growth in these new services is concentrated in those under age 45, those with college degrees and those with incomes over USD 100,000 annually, the researchers found. These groups have large numbers who use several of the on-demand platforms.
The survey, first in a series on the "new digital economy," comes amid increased debate on how new online services are disrupting traditional sectors such as the taxi and hotel industry, and how jobs are being transformed in a so-called "gig economy" of flexible work but without labor benefits.
