How Many "Places" Exist in the United States?

The United States comprises a complex political geography beyond just the 50 states:

• 50 States
• 1 Federal District: Washington, D.C.
• 5 Major Unincorporated Territories: Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands
• 11 Minor Unincorporated Territories: Including Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Navassa Island, Palmyra Atoll, Wake Island, and others.
