About Fairfax County, Virginia

Fairfax County is the largest county in Northern Virginia, with a population of over 1.1 million and a median household income exceeding $103,000—second only to neighboring Loudoun County. The area offers a mix of established neighborhoods, thriving new developments, and strong economic performance, including one of the lowest unemployment rates in the region.

Residential Growth & Communities

In the past decade, areas like Lorton, Fairfax Station, Centreville, Chantilly, and Fair Lakes have attracted homebuyers with luxury housing options and access to major transportation corridors. The county’s proximity to Washington, D.C. makes it especially appealing to professionals who want a manageable commute without sacrificing space, school quality, or community amenities.

Many relocating buyers begin their home search in Centreville, Kingstowne, Lorton, Fairfax Station, and West Springfield—all popular neighborhoods with a mix of housing, transit options, and shopping.

Key Transportation Infrastructure

Fairfax County’s infrastructure continues to evolve to meet regional demands:

  • The Springfield Interchange (I-95/I-495 “Mixing Bowl”) has improved traffic flow and safety.

  • The I-95 Express Lanes and I-495 Express Lanes offer faster commutes (E-ZPass Flex required).

  • The Silver Line Metrorail Extension now connects Dulles International Airport to the rest of the D.C. Metro area.

These projects are part of a long-term strategy to support growth while improving quality of life for residents.
