61% of American cell phone owners can be classified as smartphone owners, according to a new study [PDF] from the Pew Research Center’s Internet & American Life Project. That’s slightly higher than a recent comScore estimate of 58% mobile market penetration (though that was in the 13+ population, rather than the adult population), and leads the researchers to note that it means that 56% of all American adults are now smartphone owners. The study notes that smartphone ownership is higher among younger age groups, and similar increases within each group alongside household income level.
Looking at age groups, the study reveals that 8 in 10 adults aged 18-24 (79%) and 25-34 (81%) now own a smartphone. That figure drops to 69% among 35-44-year-olds, and continues to decrease among older brackets, all the way down to 18% of those aged 65 and older. Read the rest at MarketingCharts.
