The Mid-Atlantic is a region of the United States located in the overlap between the Northeastern and Southeastern states of the United States. The region typically includes the five states of New York, New Jersey, Pennsylvania, Delaware, and Maryland, the District of Columbia, and occasionally Virginia and West Virginia.

The Mid-Atlantic region played an instrumental and historic role in the nation's founding and the development of the nation. Each of the seven states were members of the Thirteen Colonies that gathered in Philadelphia during the Second Continental Congress, which unanimously adopted the Declaration of Independence in 1776, formalized the Continental Army under George Washington's command that escalated and ultimately won the American Revolutionary War over British colonialists. Following independence, the states again gathered in Philadelphia at the Constitutional Convention, where, in 1788, they ratified the United States Constitution, which remains the oldest and longest-standing written and codified national constitution in force in the world today.

The Mid-Atlantic region was settled during the colonial era between the early 17th century and the conclusion of the American Revolutionary War in 1783 by European Americans of primarily Dutch, German, Swedish, English, and other Western European ethnicities. Religious pluralism and freedoms existed in the original Thirteen Colonies and were particularly prevalent in Province of Pennsylvania and the geographic region that ultimately broke from Pennsylvania to form the Delaware Colony. Among the 13 original colonies, the Province of Maryland was the only colony with a substantial Catholic population.

Following the American Revolutionary War, the Mid-Atlantic region hosted each of the historic capitals of the United States. The nation's capital was constructed in Washington, D.C., and relocated there from Philadelphia following its completion in 1800. In the early part of the 19th century, New York and Pennsylvania overtook Virginia as the most populous states and overtook New England states as the country's most important trading and industrial centers. Large numbers of German, Irish, Italian, Jewish, Polish, and other immigrants transformed the region, especially coastal cities, including New York City, Newark, Philadelphia, Baltimore, and interior cities such as Pittsburgh, and Rochester, Albany, and Buffalo, with their skyscrapers and subways, which emerged as icons of modernity and American economic and cultural power in the 20th century. By the 21st century, the coastal areas of the Mid-Atlantic were thoroughly urbanized.

In the late 19th century, the region played a vital and historic role in the development of American culture, commerce, trade, and industry sectors. It was labeled "the typically American" region by historian Frederick Jackson Turner.

The Northeast Corridor and Interstate 95 link an almost contiguous sprawl of suburbs and large and small cities, forming the Mid-Atlantic portion of the Northeast megalopolis, one of the world's most important concentrations of finance, media, communications, education, medicine, and technology. The Mid-Atlantic is a relatively affluent region of the nation, having 43 of the 100 highest-income counties in the nation, based on median household income, and 33 of the top 100, based on per capita income. Most of the Mid-Atlantic states rank among the 15 highest-income states in the nation, by median household income and per capita income.

The region is home to three of the top ten-ranked universities in the nation: Princeton University in Princeton, New Jersey, Johns Hopkins University in Baltimore, and the University of Pennsylvania in Philadelphia, according to U.S. News & World Report's 2022-23 College Ranking.

Composition

There are differing interpretations as to the composition of the Mid-Atlantic, with sources including in the region a number of states from New York to South Carolina. A United States Geological Survey publication describes the Mid-Atlantic Region as all of Maryland, Delaware, the District of Columbia, Pennsylvania, and Virginia, along with the parts of New Jersey, New York, and North Carolina that drain into the Delaware and Chesapeake Bays and the Albemarle and Pamlico Sounds. Sometimes, the region's nucleus is considered to be the area centered on the Washington metropolitan area, including Maryland, Delaware, Virginia, and West Virginia.

In contrast to other definitions in which the Mid-Atlantic overlaps the Northeast and Southeast, the United States Census Bureau defines the Mid-Atlantic as a subregion of the Northeast consisting exclusively of New York, New Jersey, and Pennsylvania.

West Virginia and Virginia are atypical in the region as the only states to lie primarily within the Southern American dialect region, and the major religious tradition in being largely Evangelical Christian, with 30% in Virginia and 39% in West Virginia identifying as evangelicals. Although a few of West Virginia's eastern panhandle counties are considered part of the Washington metropolitan area, the major portion of the state is rural and there are no major or even large cities.

History

Shipping and trade have been important to the Mid-Atlantic economy since the beginning of the colonial era. The explorer Giovanni da Verrazzano was the first European to see the region in 1524. Henry Hudson later extensively explored that region in 1611 and claimed it for the Dutch, who then created a fur-trading post in Albany in 1614. Jamestown, Virginia was the first permanent English colony in North America, it was established seven years earlier in 1607.

From early colonial times, the Mid-Atlantic region was settled by a wider range of European people than in New England or the South. The Dutch New Netherland settlement along the Hudson River in New York City and New Jersey, and for a time, New Sweden along the Delaware River in Delaware, divided the two great bulwarks of English settlement from each other. The original English settlements in the region notably provided refuge to religious minorities, Maryland to Roman Catholics and Pennsylvania to Quakers and Anabaptist Pennsylvania Dutch. In time, all these settlements fell under English colonial control, but the region continued to be a magnet for people of diverse nationalities.

The area that came to be known as the Middle Colonies served as a strategic bridge between the North and South. The New York and New Jersey campaign during the American Revolutionary War saw more battles than any other theater of the conflict. Philadelphia, midway between the northern and southern colonies, was home to the Continental Congress, the convention of delegates who organized the American Revolution. Philadelphia also was the birthplace of the Declaration of Independence in 1776 and the United States Constitution in 1787, while the United States Bill of Rights was drafted and ratified and the first Supreme Court of the United States sat for the first time, in the first capital under the Constitution of New York.

While early settlers were mostly farmers, traders, and fishermen, the Mid-Atlantic states provided the young United States with heavy industry and served as the "melting pot" of new immigrants from Europe. Cities grew along major ports, shipping routes, and waterways, including New York City and Newark on opposite sides of the Hudson River, Philadelphia on the Delaware River, Allentown on the Lehigh River, and Baltimore on the Chesapeake Bay.

Notable motorsports tracks include Watkins Glen International, Dover Motor Speedway and Pocono Raceway, which have hosted Formula One, IndyCar, NASCAR, World Sportscar Championship and IMSA races. Also, the Englishtown and Reading drag strips such have hosted NHRA national events.

Economy

With a GDP nominal of over $5.2 trillion, the Mid-Atlantic economy would be third largest in the world if calculated separately, only behind the remaining United States and China and nearly $1 trillion larger than next place Japan. This economic prosperity is buoyed by a significant financial services and banking sector, healthcare and chemicals industry, and telecommunications and entertainment conglomerates.

According to the Global Financial Centres Index, the Mid-Atlantic region is home to the leading financial center in the world (New York) at #1, with Washington also present at #15.
