U.S. states

U.S.

By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 26, 2026|2 min read| Fact-checked

U.S. states are the 50 constituent political entities that make up the United States of America. They share sovereignty with the federal government and each has its own state government. Four states officially use the title "commonwealth" rather than "state," but their legal status is the same as the others.

Definition

U.S. states are the 50 federated units of the United States. They are subnational political entities that share powers with the federal government under the U.S. constitutional system.

Government and status

Each state has its own government and operates within powers reserved to it by the Constitution. Although four states use the style "commonwealth," this does not create a different legal category from other states.

Geographic distribution

Most states are in the contiguous mainland of North America. Alaska and Hawaii are geographically separate from the contiguous 48 states.

States versus other U.S. jurisdictions

The U.S. states are distinct from Washington, D.C., which is a federal district, and from U.S. territories such as Puerto Rico and Guam.

  • States share sovereignty with the federal government.
