The United States is made up of 50 states, one federal district (Washington D.C.), and one incorporated territory. States have significant powers under the U.S. Constitution such as regulating commerce within the state and electing representatives to Congress. Each state has its own executive, legislative, and judicial branches of government. New York is one of the most populous and densely populated states, located in the Northeast and bordering several other states and Canada. Major landmarks in the U.S. include the Statue of Liberty in New York, Times Square in Manhattan, the White House in Washington D.C., Denali National Park in Alaska, and the Las Vegas Strip known for its casinos.
