Languages of the United States facts
English is the de facto national language of the United States, with 82% of the population claiming it as a mother tongue, and some 96% claiming to speak it "well" or "very well". However, no official language exists at the Federal level. There have been several proposals to make English the national language in amendments to immigration reform bills, but none of these bills have made a federal language. However, some states have adopted the English language as their official language.
French language distribution in the United States. Counties and parishes marked in yellow are those where 6% to 12% of the population speak French at home; brown, 12% to 18%; red, over 18%. Cajun French and French-based creole languages are not included even though the Creole dialects are spoken throughout the U.S. and taught in many U.S. schools.
