As smartphones and other internet-connected devices have become more widespread, 31% of U.S. adults now report that they go online “almost constantly,” up from 21 percent in 2015, according to a new Pew Research Center survey conducted Jan. 25 to Feb. 8, 2021.

Overall, 85 percent of Americans say they go online on a daily basis. That figure includes the 31 percent who report going online almost constantly, as well as 48 percent who say they go online several times a day and 6 percent who go online about once a day. Some 8 percent go online several times a week or less often, while 7 percent of adults say they do not use the internet at all.

Adults under the age of 50 are at the vanguard of the constantly connected: 44 percent of 18- to 49-year-olds say they go online almost constantly. By comparison, just 22 percent of those ages 50 to 64 and even smaller shares of those 65 and older (8 percent) say they use the internet at this frequency.
