As smartphones and other mobile devices have become more widespread, 28% of American adults now report that they go online “almost constantly,” up from 21% in 2015, according to a Pew Research Center survey conducted Jan. 8 to Feb. 7, 2019. Overall, 81% of Americans say they go online on a daily basis. That figure includes the 28% who go online almost constantly, as well as 45% who say they go online several times a day and 9% who go online about once a day. Some 8% go online several times a week or less often, while 10% of adults say they do not use the internet at all.
