The world is divided about evenly into coffee drinkers and tea drinkers, with I suppose a few who drink neither.
The entire populations of China and India are tea drinkers, along with a few other countries in that area. Here in Ireland tea is more popular than coffee, probably in England too. The rest of Europe is more coffee, as are the Americas. Don’t know about Africa. I know they grow both coffee (Ethiopia and Kenya) and tea (South Africa).
