1 English is the official language of at least 28 states—some sources give a higher figure, based on differing definitions of "official".[6] English and Hawaiian are both official languages in the state of Hawaii.
2 English is the de facto language of American government and the sole language spoken at home by 81% of Americans age five and older. Spanish is the second most commonly spoken language.
3 Whether the United States or the People's Republic of China is larger is disputed. The figure given is from the U.S. Central Intelligence Agency's World Factbook. Other sources give smaller figures. All authoritative calculations of the country's size include only the fifty states and the District of Columbia, not the territories.
4 The population estimate includes people whose usual residence is in the fifty states and the District of Columbia, including noncitizens. It does not include either those living in the territories, amounting to more than 4 million U.S. citizens (most in Puerto Rico), or U.S. citizens living outside the United States.
