In the early 20th century, Potomac City remained rural, but gradual suburban expansion from Washington, D.C., began to reach the area after World War II.

Large estates, equestrian properties, and preserved open space became part of its defining character.
According to Montgomery County historical archives, Potomac City is now recognized as one of the most affluent communities in the United States, with high-ranking schools, protected parklands, and a strong tradition of civic engagement.
Today, Potomac City is part of the Washington metropolitan area, sharing economic, cultural, and transportation connections with the nation’s capital and surrounding Maryland and Virginia suburbs.
