Starbucks was born out of Seattle, so it's no surprise that the United States boasts more outlets of the cafe than any other country in the world (more than 11,500).
Canada is number two on that ranking, though, and actually ahead of the US—and everyone else—on a per-capita basis, with 40 stores per million people, according to Quartz.
Starbucks has been an innovative force in mobile payments in North America. Powered by one of the better retail apps, Starbucks has 10 million mobile users, making it the most-used mobile payments app on the continent. These consumers combine for 4% of all mobile payments, which led to more than $1 billion in mobile payment revenue for Starbucks in 2013.
