From the Pew FactTank:
“Roughly three-in-ten adults with household incomes below $30,000 a year (29%) don’t own a smartphone. More than four-in-ten don’t have home broadband services (44%) or a traditional computer (46%). And a majority of lower-income Americans are not tablet owners. By comparison, each of these technologies are nearly ubiquitous among adults in households earning $100,000 or more a year.”
