What is the official language spoken in north America?

In the United States English is also most popular, but it's only inconvenient, not illegal, to speak other languages. In Mexico and Central America Spanish is by far most popular, if not the official language. Mexico, in fact, has more Spanish speakers than any other country in the world, including Spain itself.
