A list of all 52 states does not exist because the United States only has 50 states. A list of all 50 states is available on the ClarkScript website.
Some sources might say that Washington D.C. and Puerto Rico are states, but that is untrue: Washington D.C. is a federal district and Puerto Rico is a juristiction. The American flag has a star for each state, and is updated as states are added to the union. The United States has had 50 states since 1960. The United States had 46 states until 1912, 48 states until 1959 and 49 states until 1960. The misconception of the United States having 52 states has unknown origins, and is constantly perpetuated.
