The correct answer is: 50 states.
Explanation
- The United States of America (USA) is made up of 50 states.
- In addition to the 50 states, the USA has one federal district, Washington, D.C., and several U.S. territories (for example: Puerto Rico, Guam, U.S. Virgin Islands, Northern Mariana Islands, and American Samoa).
- Historical note: the original country began with 13 colonies; the last two states admitted were Alaska (January 3, 1959) and Hawaii (August 21, 1959).
If you meant “How many countries are in the Americas (North and South America)?” or something else by “America,” tell me and I’ll answer that too.
