Connecticut is the southernmost state in the New England region of the northeastern United States. As of the 2010 Census, Connecticut features the highest per-capita income, Human Development Index 0.962, and median household income in the United States. Connecticut is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. Although Connecticut is technically part of New England, it is often grouped along with New York and New Jersey as the Tri-state area. The state is named for the Connecticut River, a major U.S. river that approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of an Algonquian word for "long tidal river".
