The two beverages have ancient roots, but only over the last couple of centuries have they become truly global commodities. The following map from The Economist shows which countries and regions favor which drink. (You can find the interactive version here.)
There is a clear East-West divide: among nearly all Western countries — with the notable exception of the United Kingdom — coffee trounces tea, despite the latter beverage’s increasing popularity. Meanwhile, across most of Africa and Asia, tea is the drink of choice, with the Philippines, South Korea, and Thailand being clear outliers.
Other countries such as Australia, Chile, New Zealand, and Saudi Arabia remain divided. Guatemala stands out as being the most overwhelmingly favorable towards coffee (99.6 percent) while Kenyans are the most enthusiastic for tea (99.2 percent). Overall, most countries prefer coffee, though tea probably has the most total drinkers, given its popularity in big nations like China, India, and Nigeria.
