Through Atlantic Ocean, Ecoregion and Logistics

South Jersey is part of the Philadelphia metropolitan area, the seventh-largest metropolitan region in the nation with 6.288 million residents in the core metropolitan statistical area and 7.366 million residents in the combined statistical area of Camden, Philadelphia and Wilmington, as of 2020. South Jersey is known for containing the unique ecoregion known as the Pine Barrens, which remains largely undisturbed despite its location within the Northeastern megalopolis. The South Jersey Pine Barrens are the largest remaining example of the Atlantic coastal pine barrens ecosystem.

Benjamin Franklin is said to have called New Jersey "a barrel tapped at both ends", referencing the Philadelphia influence on South Jersey and the New York City influence on North Jersey. South Jersey is generally defined geographically as the area below I-195 that includes the state's lower seven counties: Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, and Salem, and occasionally an eighth, Ocean.

South Jersey and the wider Philadelphia metropolitan area are situated near the center of the Northeast megalopolis and have become a U.S. East Coast epicenter for logistics and warehouse construction; Salem County, the lower portion of Gloucester County, and the upper portion of Cumberland County additionally serve as residential communities for the petrochemical industry of New Castle County, Delaware. South Jersey shore communities, including Atlantic City and others in Atlantic and Cape May counties, have a distinct economy centered around the tourism industry. Burlington, Camden, and Gloucester counties have several older streetcar towns, and many residents from these three counties commute to Philadelphia, the nation's sixth-most populous city, which is located immediately west of South Jersey across the Delaware River, accessible by the Benjamin Franklin Bridge, Betsy Ross Bridge, Tacony Palmyra Bridge and Walt Whitman Bridge.

The designation of South Jersey with a distinct toponym is a colloquialism rather than an administrative definition and reflects geographical and perceived cultural and other differences between South Jersey and the northern part of the state.

Geography

Topography

South Jersey is a peninsula bordered by the Atlantic Ocean to its southeast, the Delaware Bay to its southwest, and the Delaware River to its northwest. All of South Jersey is part of the Atlantic Plain, a landform of broad plains and gently sloping hills that extends southward from the New York Bight to Florida. Much of the Atlantic Plain is covered by pine and oak-pine forests and salt marshes and is underlain by poorly consolidated sedimentary formations from the Cretaceous, Tertiary, and Quaternary ages that dip seaward. The Atlantic Coastal Plain can be divided into three physiographic subprovinces: the Inner Lowlands, Outer Lowlands, and Central Uplands.

The Inner Lowlands region encompasses the low valley along the Delaware River, with an elevation ranging from 50 feet (15 m) to 100 feet (30 m), and the Outer Lowlands encompasses the area near the Atlantic Ocean with an elevation that rarely exceeds 50 feet (15 m). The Inner Lowlands are fertile due to the deposition of sediment in the region, which makes it an ideal region for agriculture. The Outer Lowlands is dominated by coastal estuaries, swamplands, and barrier islands near the Atlantic Ocean and is generally infertile. The Central Uplands varies slightly from the Lowlands in altitude and is covered by the New Jersey Pine Barrens. The Uplands has rolling hills at an elevation over 50 feet, rarely exceeding 200 feet in elevation, along with sandy, acidic soil that is unsuitable for agriculture. Commercial farming in the Pine Barrens is limited to plants that thrive in its nutrient-poor soil, generally restricted to acidic fruits. In the Pine Barrens, cranberries and blueberries are cultivated in lowland bogs that have accumulated depths of organic matter.

Climate

South Jersey has a humid subtropical climate. Compared to northern parts of New Jersey, South Jersey has slightly higher temperatures and receives less annual precipitation. Along the Jersey Shore, temperatures are moderated by sea breezes.
