The Delaware Valley is the name of the metropolitan area centered on the city of Philadelphia in the United States. The region is named for the Delaware River which flows through it. The Office of Management and Budget officially defines the region as the Philadelphia–Camden–Wilmington metropolitan area.

The Delaware Valley is composed of several counties in Delaware, New Jersey, Maryland, and Pennsylvania, and contains a population of 5.8 million (as of the 2006 Census Bureau estimate). However, if the populations of all Delaware Valley counties is tallied, (see below), then the actual population of the Delaware Valley is 6,220,778. Philadelphia, being the region’s major commercial, cultural, and industrial center, maintains a rather large sphere of influence that affects those counties that immediately surround it. The majority of the region’s populace reside in Pennsylvania and New Jersey.

The Philadelphia–Camden–Wilmington is the fifth-largest metropolitan area in the United States and is located towards the southern end of the BosWash megalopolis, the name given for a group of metropolitan areas in the northeastern United States, extending from Boston to Washington, D.C.

Based on commuter flows, a wider labor market region known as the Philadelphia–Camden–Vineland combined statistical area (CSA) is additionally defined. This wider region adds the metropolitan areas of Vineland and Reading and has a total population of 6.3 million.

Despite the area’s size and dominance in 4 states, no state capitals are within the Delaware Valley (Philadelphia) Metropolitan Area. Trenton, the capital of New Jersey, is on the Delaware River and was formerly part of the Delaware Valley, but since 2000 has officially been part of the New York Metro Area.


The area has extensive suburban sprawl. King of Prussia, Pennsylvania, and Cherry Hill, New Jersey are two of the largest suburban edge cities. Philadelphia’s suburbs contain a high concentration of malls including the King of Prussia Mall, the largest on the East Coast and the Cherry Hill Mall in Cherry Hill, New Jersey, the first enclosed mall on the East Coast. Malls, office complexes, strip shopping plazas, expressways, and tract housing are common sites, and more and more are continued to be constructed as these replace rolling countryside, farms, woods, and wetlands. However, recent opposition made by residents and political officials, many acres of land have been preserved throughout the Delaware Valley. Older small towns and large boroughs such as Norristown, Jenkintown and West Chester remain while engulfed in suburbia. The fastest growing counties are Chester, Montgomery, Bucks, and Gloucester. Many of the counties outside the metropolitan area are also experiencing rapid growth, such as Lancaster County, Lehigh County, Northampton County, and Berks County. South Jersey is experiencing faster growth than the rest of the state.

Counties Adjacent to the Delaware Valley

The counties listed below are not physically or officially part of the Delaware Valley, according to the U.S. Census Bureau. However, these counties have seen increased growth and growing links to the Philadelphia Metropolitan Area and the Delaware Valley in recent years. This trend is due to increased economic trade and transportation links to the Delaware Valley. In recent decades, there has also been a rapid trend of out migration from Philadelphia and its suburbs by commuters and others seeking lower housing prices and a lower cost of living, further linking these counties with the greater Philadelphia area.

While unlikely in the near future, it is not impossible to assume that some of these counties will one day be considered part of the Philadelphia Metropolitan Area and the Delaware Valley if rapid population and economic growth continues. For example, Berks County, which long bordered the Delaware Valley, was recently added to the metropolitan area by the U.S. Census in 2005. Lehigh and Northampton County continue to remain distinct, since they receive more migrants from the New York City metropolitan area than the Delaware Valley.

In contrast, Mercer County, New Jersey had formerly been part of the Delaware Valley Metropolitan Area. However, it was redesignated as part of the New York Metropolitan Area in 2000.


* Kent County
* Sussex County

* Atlantic County
* Cape May County
* Mercer County (part of the New York Metropolitan Area)
* Monmouth County (part of the New York Metropolitan Area)
* Ocean County (part of the New York Metropolitan Area)

* Northampton County


Many residents commute to jobs in Philadelphia, Camden, Wilmington, and increasingly as far as New York City, with the help of expressways and trains. Commutes from one suburb to another are also common, as office parks have sprung up in new commercial centers such as King of Prussia, Fort Washington, Cherry Hill, and Plymouth Meeting.

Lexicon note

Some believe that the term “Delaware Valley” is subtly different than “Greater Philadelphia.” “Greater Philadelphia” implies that the region is centered on the city in an economic and cultural context, while “Delaware Valley” is a more generic geographic term that doesn’t imply that any part is of more consequence than any other. Several organizations, such as KYW Radio and the Greater Philadelphia Tourism Marketing Corporation, consciously use the term “Greater Philadelphia” to assert their view that Philadelphia is the center of the region, and that the suburbs are only relevant as, in GPTMC’s terms, “Philadelphia’s countryside.”

Many who work and live in the suburbs and rarely if ever visit the city don’t agree and tend to use the term “Delaware Valley,” which lacks the dominant city vs. dependent suburbs subtext.

WPVI-TV uses the slogan, “The Delaware Valley’s leading news program” for their Action News broadcast, since that program has led the ratings for news programs in the Philadelphia market for over 30 years.

The Delaware Valley is also sometimes called “the Tri-State area,” referring to Pennsylvania, New Jersey, and Delaware.
