The term “US states by number” refers to the numerical order in which the 50 states of the United States were admitted into the Union. For instance, Delaware is the first state, admitted in 1787, while Hawaii is the 50th, admitted in 1959.
Understanding the order of statehood is significant for historical comprehension and geographic organization. It provides a framework for examining the nation’s growth and westward expansion. The chronological listing of states highlights key milestones in American history and territorial development.
