In U.S. and U.K., 10-12% of Internet Users are "Mobile Only"
More than 90 percent of Australians under 50 go online using a mobile phone. That does not mean that “only” do so using a mobile device, only that the behavior is ubiquitous.
As with many other aspects of Internet behavior, older age cohorts use their mobile devices to use Internet apps at a lower rate.
Some 75 percent of all consumers in Australia access the internet using a mobile phone, according to a June 2016 survey by Sensis.
But that figure is because just 61 percent of those ages 50 to 64 do so, and just 33 percent of those ages 65 and up do the same.
For some, the more interesting question is what percentage of people use “only” the mobile device for Internet access.
In earlier 2016, for example, 11.7 percent of U.S. Internet users were going online exclusively using a mobile device mobile device, and do not use personal computers or other devices at all.
In fact, since 2015, according to comScore, there are more “mobile-only” than “desktop only” Internet users.
In the United Kingdom, about 10 percent of Internet users use mobile exclusively to get online, according to Ofcom.
