Pew asked 2,253 adults about their mobile phone in a survey conducted last month, and the results suggest that smartphones have finally overtaken dumb phones in the US. The survey shows that 45 percent of cell owners say their phone is a smartphone, and 49 percent of cell owners say that their phone operates on a smartphone platform. These numbers are up from 33 percent and 39 percent in 2011, respectively.
Not surprisingly, the biggest group of smartphone adopters are college graduates, 18-35 year-olds and people with an annual household income of $75,000 or more. In these groups smartphone penetration climbs as high as 60 percent. The lowest group of smartphone owners are senior citizens (13 percent) and people who never graduated from high school (25 percent). The survey also revealed that a surprisingly high 8 percent of mobile phone owners do not know if their phone is a smart phone or a dumb phone.
