US States Atlas
50 states + the District of Columbia

Compare any two states

Population, land area, gross domestic product, capital, and statehood date — pick two states below, or click two tiles on the map.

State A
VS
State B
Click a state to set it as State A. A tile-grid layout gives every state equal visual weight, at the cost of some real adjacencies (e.g. New York doesn't touch the map's eastern edge here, unlike on a true map) — real published grid coordinates, not traced borders.
