North America

From Teflpedia

North America is a continent in the Northern hemisphere, containing United States, Canada, Mexico and various other smaller countries and territories.

North America is the only continent where the majority of people speak English as a first language, and it is the continent where most native English speakers live. (It would be good to put some approx. numbers on this).

North American English is therefore the most common dialect of English, consisting of American English and Canadian English.
