What is the Geography of the Delaware Valley?
The Delaware Valley is closely connected to the Delaware River. This river has three main branches: the Schuylkill River, Lehigh River, and Brandywine Creek.
The U.S. government uses different ways to define areas like the Delaware Valley. A metropolitan statistical area (MSA) is a region with many people living close together. These areas also have strong economic ties. MSAs can be grouped into larger combined statistical areas (CSAs), which show how people commute between different areas. These are not official government borders, but ways to understand population and economy.
What is a Metropolitan Statistical Area (MSA)?
The main part of the Delaware Valley is called the Philadelphia-Camden-Wilmington Metropolitan Statistical Area. It includes counties from Pennsylvania, New Jersey, and Delaware, plus one county from Maryland.

What is the Colonial History of the Delaware Valley?
Long ago, the Delaware Valley was home to the Susquehannock and Lenape Native American tribes. You can still see their names in many places today.

In 1638, people from Sweden, Finland, and the Netherlands started to settle here, creating the colony of New Sweden. However, the Dutch took control again in 1655. Then, in 1664, the English took over the area.
The name Delaware comes from Thomas West, 3rd Baron De La Warr. He arrived in Virginia in 1610 and helped keep the English presence in North America. In the early 1700s, French refugees, called Huguenots, also settled in the Delaware River Valley.
