Northeastern United States

region of the United States

The Northeastern United States, or simply the Northeast, is a region defined by the US Census Bureau. It consists of New England, New York, Pennsylvania and New Jersey. The border States of Delaware and Maryland and other states are sometimes included in other definitions of the Northeast. Cities in the Northeast include Boston, Philadelphia and New York City.

The following table provides information about the population, size (land area) and population density of states in the Northeast region as defined by the U.S. Census bureau. Population density is defined as the population divided by the area of land in the state or region. The rank column in the table shows how the states rank among the entire 50 states in population density. Note that New Jersey has the highest population density of any state and that the 4 highest density states are all in the Northeast. The rank for the Census divisions (in pink) is the rank in population density among the 9 total divisions in the country. Note that the two divisions in the Northeast (New England and Mid-Atlantic) are ranked #1 and #2 in the 2013 population estimate. The South Atlantic region was close behind New England and is projected to surpass New England in the next population estimate because it is growing faster. Finally, note that the entire Northeast region is ranked #1 among the 4 Census Bureau regions. With 345.5 people per square mile, the population density of the Northeast is about 2.5 times the density or the #2 ranked region which is the South.
