There are approximately 310 million people in the United States. Of these people, approximately 250 million are over the age of 14. According to Comscore, about 235 million of these Americans use mobile devices. It seems likely that almost all of these folks will eventually have smartphones.
But the world is starting to catch up with North America, according to Ericsson. By 2020, global smartphone subscriptions will more than double to 6.1 billion, 70 percent of people will use smartphones, and 90 percent will be covered by mobile broadband networks. That surge, Ericsson said, is due in part to the growing number of devices per person in mature markets like North America and Europe.
