Marumsco, Virginia
Background
The U.S. Census Bureau designated Marumsco as separate from Woodbridge in 2010. Almost 90 percent of residents who lived in Woodbridge in 2000, along with 80 percent of the land, became part of Marumsco. The area was re-designated part of Woodbridge again prior to the 2020 census.
With a population of about 37,000 residents and a density of about 5,000 residents per square mile, the Marumsco CDP covered a large portion of U.S. Route 1 in Prince William County. The area experiences high traffic volumes consisting of residents and commuters going north typically to Fairfax County as well as the D.C. metropolitan area. The Marumsco CDP extended on both sides of Route 1 from Occoquan Road in the north to Optiz Boulevard in the south. Further south, the CDP continued on the east side of Route 1 as far as Rippon Boulevard. The entire area as of 2020 is once again part of the Woodbridge CDP.
