The sharing economy could cause a digital divide.
A Pew study found Americans' age and income impacts who uses sharing apps like Uber and Airbnb.
Young adults use ride-hailing and home-sharing apps more than the over-45 crowd.
And Americans with an annual income of at least $75,000 are more likely to use these services than lower-income individuals.
College graduates are also more likely to use sharing services than those with less schooling.
The socioeconomic divide comes down to exposure, too.
The majority of low-income Americans have just never heard of these services — no wonder they're not using them.
