Why does everyone think there are 51 states? The definitive look at US geography, territories, and historical expansion.
The simple answer is 50. The United States has exactly 50 states, a number that has remained unchanged since August 21, 1959, when Hawaii was admitted as the final state to the Union (just a few months after Alaska became the 49th).
Yet, search queries for "how many states are in the USA" remain staggeringly high because of lingering geographical and civic confusion. Here is what actually muddies the waters:
Washington, D.C.: The nation’s capital is a federal district, not a state. It sits on land ceded by Maryland and Virginia so that the federal seat of power would not be beholden to any single state’s laws.
The Inhabited Territories: The US exercises sovereignty over five major inhabited overseas territories: Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands.
The 51st State Debate: Puerto Rico alone has a population of over 3.2 million people—larger than 21 individual US states. Ongoing local votes and congressional bills regarding Puerto Rican statehood keep the "51 states" concept constantly in the news cycle.
Fun point of comparison: The USA actually contains more states (50) than there are independent countries across the entire continent of Europe (44)! It all started with just 13 original colonies breaking away from Great Britain in 1776, expanding westward over centuries via treaties, purchases, and conflict.
