Bihari Community in Washington DC
3,771 Hindi-belt households in Herndon–Reston PUMA • Chhath Puja at Algonkian Park since 2006 • BJANA DC Metro • Dulles Tech Corridor • Federal agencies in Gaithersburg/Rockville
The Bihari community in the Washington DC metro area has built its roots along the Dulles Technology Corridor — principally Herndon, Reston, and Sterling in Northern Virginia — with a secondary cluster in Montgomery County, Maryland (Gaithersburg and Rockville). The community’s organizational anchor is BJANA DC Metro (Bihar Jharkhand Association of North America — Washington DC Chapter), the dedicated local chapter of the 1976-founded national organization. The defining annual event is the Chhath Puja at Algonkian Regional Park in Sterling, VA — started in 2006 by software engineer Kripa Shankar Singh from Patna, now drawing 500+ participants and recognized as one of the oldest Chhath celebrations in the United States. In the Herndon–Reston PUMA, Hindi is the third-largest overall language in the metro with 3,771 Hindi-belt households, confirming this corridor as the North Indian / UP-Bihar capital of the DMV.

Why Bihari Families Choose Washington DC
The Bihari professional profile in Washington DC is distinct from every other US metro. In Houston it’s medicine. In NYC it’s finance. In DC, it is IT government contracting and federal research. The Dulles Technology Corridor — Herndon, Reston, Ashburn, Chantilly, Sterling — is the employment spine: Booz Allen Hamilton, SAIC, Leidos, Northrop Grumman, CACI, and dozens of federal IT contractors with clearance-eligible positions populate this 30-mile corridor. Federal agencies including NSA, DHS, DoD, and the State Department’s IT operations cluster here. Bihari engineers and IT professionals, who emerged from the IIT and NIT pipeline (IIT Patna, NIT Patna, IIT BHU Varanasi, BIT Mesra), have found this corridor to be as natural a landing point as Silicon Valley is for Telugu engineers.
The Maryland cluster has a different driver. NIH’s main campus in Bethesda, FDA headquarters in Silver Spring, and NIST in Gaithersburg draw Bihari scientists and researchers in biomedical research, drug regulation, and standards. The Montgomery County school system — consistently ranked among Maryland’s best — keeps research families rooted in Gaithersburg and Rockville once children are school-age.
What distinguishes DC from other Bihari diaspora metros is the Chhath Puja geography. The Potomac River runs through Loudoun County — directly adjacent to the Bihari residential corridor in Sterling and Ashburn. When Kripa Shankar Singh organized the first Chhath gathering at the Potomac boat ramp in 2006, it was not coincidental: he lived here, his community lived here, and the river was a five-minute drive away. The Chhath tradition at Algonkian Regional Park has now grown for two decades, and it roots the community to this specific landscape in a way no other diaspora event quite replicates.
Where Bihari Families Live in the DC Metro
Bihari immigrants speak Hindi (and Bhojpuri, Maithili, or Magahi at home) — all counted under the Census “Hindi” category — making precise isolation difficult. But PUMA language data tells the story clearly: the corridors with Hindi dominance are the Bihari corridors. Unlike Ashburn and Loudoun County, where Telugu dominates (8,612 Telugu households), Herndon and Reston show Hindi as the leading Indian language — the clearest possible marker of a UP/Bihar community footprint.
Herndon & Reston (Fairfax County NW PUMA) — The Primary Cluster (3,771 Hindi HH)
The Reston (North) & Franklin Farm PUMA has 12,423 India-born residents — 7.2% of the PUMA population, the second-largest birthplace group overall. Hindi is the third-largest language in the entire PUMA at 3,771 households, sitting above every Indian language except the broader language averages. This is definitively the North Indian / Hindi-belt capital of the DMV. The employment base explains it: the Dulles Toll Road corridor concentrates tech contractor offices within commuting distance of Herndon Pkwy (ZIP 20170) and the Route 7 / Route 28 intersection. Residential housing includes planned communities and apartment corridors off Herndon Pkwy, Centreville Rd, Sterling Blvd, and Algonkian Pkwy. The Herndon area has its own Indian commercial infrastructure — Aditi Spice Depot and Hello2India grocery stores, multiple North Indian restaurants on Herndon Pkwy — making it possible to live entirely within the community without a long drive.
Sterling & Ashburn (Loudoun County) — The Chhath Corridor (4,603 Hindi HH)
The Ashburn SW/Belmont Ridge PUMA has 18,133 India-born residents with 4,603 Hindi-speaking households — the third-largest language group after Telugu. Sterling (ZIP 20165) is where the Chhath Puja at Algonkian Regional Park physically takes place, on the Potomac River shoreline. The founding of that tradition in 2006 is direct evidence of the Bihari community’s longstanding residential presence here. Amazon HQ2 in Ashburn and the broader Dulles technology campus have drawn additional North Indian tech workers. The annual Ashburn Diwali Mela at Broad Run High School draws 1,300 participants — a measure of the community’s critical mass in Loudoun County.
Gaithersburg & Rockville (Montgomery County, MD) — The Research Cluster
The Germantown/Clarksburg PUMA has 7,520 India-born residents, and the Gaithersburg/Rockville PUMA has 5,464 — with Hindi, Telugu, Tamil, and Gujarati roughly co-equal, unlike the Hindi-dominant Northern Virginia corridor. Key ZIP codes: 20877 and 20878 (Gaithersburg), 20850 and 20852 (Rockville). The draws here are NIH (National Institutes of Health, Bethesda), FDA headquarters (Silver Spring), NIST (Gaithersburg), and the biotech/pharma corridor along I-270. Bihari scientists and researchers predominate among the North Indian population here, in contrast to the IT contractor profile of Northern Virginia.
