A third of Americans live in a household with three or more smartphones
For the first time, more than half of all households in the U.S. contain a cellphone but not a landline telephone, according to a 
Younger adults and relatively affluent Americans tend to live in households with large numbers of connected devices, and this is especially true when it comes to smartphones. Some 96% of 18- to 29-year-olds live in a household with at least one smartphone, and 51% of young adults indicate that their home contains three or more smartphones.
Even so, many older adults also reside in households with multiple mobile devices. Nearly four-in-ten 30- to 49-year-olds (39%) and 29% of 50- to 64-year-olds say their home contains three or more smartphones. In total, the typical (median) 18- to 29-year-old lives in a household with six of these connected devices – a figure that is comparable to the median figure among those ages 30-49 (six) and 50-64 (five).
Higher-income Americans are about twice as likely as those who are lower income to say their household has three or more smartphones (45% vs. 25%). But affluent Americans also stand out in comparison with lower-income households when it comes to traditional computers and tablets. Four-in-ten Americans with an annual household income of $75,000 or more (41%) say they have three or more computers in their home, compared with 9% of those whose household income is $30,000 or less. And 26% of these higher-income Americans say their home contains three or more tablets, compared with 9% of those earning $30,000 a year or less.
