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.

Roughly eight-in-ten U.S. adults go online at least dailyOverall, 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.

Adults with mobile connectivity are especially likely to be online a lot. Among mobile internet users – the 86% of Americans who use the internet at least occasionally using a smartphone, tablet or other mobile device – 92% go online daily and 32% go online almost constantly.

Roughly three-in-ten Americans – and 48% of those ages 18-29 – go online 'almost constantly'Younger adults are at the vanguard of the constantly connected: Roughly half of 18- to 29-year-olds (48%) say they go online almost constantly and 46% go online multiple times per day. By comparison, just 7% of those 65 and older go online almost constantly and 35% go online multiple times per day.

The share of younger adults who say they use the internet almost constantly has risen 9 percentage points since the last time the survey was conducted in 2018. While the share of 30- to 49-year-olds who say this has risen 8 points since 2015, it remains unchanged since 2018. Meanwhile, the share of constantly online Americans ages 50 to 64 has risen from 12% in 2015 to 19% in 2019.

Other demographic groups that report going online frequently include college-educated adults, Hispanic adults, adults who live in higher-income households and nonrural residents.

Some 36% of adults with a college education or more go online almost constantly (and 93% go online daily), compared with 23% of adults with a high school education or less. At the same time, 34% of Hispanic adults report using the internet almost constantly, compared with 25% of black adults and 26% of white adults. The share of Hispanics who are almost constantly online has risen 15 points since 2015.

While 34% of adults with an annual household income of $75,000 or more use the internet almost constantly, this is true for just 23% of those living in households earning less than $30,000. Adults who live in urban and suburban areas are also more likely to say they go online almost constantly than those who live in rural areas.
