Smartphone adoption is highest among young consumers with more disposable income.
According to Nielsen, Americans aged 25 to 34 earning more than $100,000 a year have the highest smartphone usage, with penetration at an astounding 81 percent. At the other end of the spectrum, even the highest income Americans over the age of 65 "only" have 42 percent adoption, well below national penetration (which Nielsen measured at 55 percent in June).
Most interesting though is that Americans aged 18 to 24 making less than $50,000 a year still have 59 percent penetration, indicating that they view smartphones as a necessity.
