there are multiple interpretations of distinctive cultural regions of Virginia, with inconsistent terms and boundaries
Outer Continental Shelf
The Virginia Company received three charters from King James II establishing the company's claim to land in North America. The Second Charter, issued in 1609, extended the grant inland to extend from sea to sea, west and northwest. Based on that grant, Virginia at one time reached across the continent to the Pacific Ocean. It once incorporated far more land with greater variety of characteritics and people than is located within the modern state boundaries.
Virginia was already occupied when the Spanish arrived in 1570 and the English in 1607, and the Native Americans had their own regional cultures. The Native American land claims were extinguished through a variety of techniques, including simple seizure of territory, warfare, treaties, and purchases. There were a few attempts by Native Americans to retain land ownership in certain locations using the colonial legal system, and several reservations were created. Those created for the Nottoway and Gingaskins were extinguished and land sold to non-native owners, but the reservation created for the Pamunkey tribe has survived to the present day (including the component now occupied by the Mattaponi).
Starting in 1620, Virginia's boundaries were reduced by the creation of new colonies, first in Massachusetts, then in Maryland and the Carolinas. During the American Revolution, Virginia voluntarily ceded to the new national government its claims to lands west of the Ohio River. One Virginian, Thomas Jefferson was instrumental in determining how the Noerthwest Territory would be governed and converted into new states.
unlike the creation of the Massachusetts Bay Colony, the creation of Maryland blocked Virginians from owning land they had already settled (such as William Claiborne's fur trading station on Kent Island)

After adoption of the Constitution, the counties on the far western edge of Virginia were organized as the new state of Kentucky, with Virginia's support. The final loss of territory occurred during the Civil War, when most of the remaining Virginia counties on the Appalachian Plateau formed the new state of West Virginia. The reductions in territory still left Virginia with enough variety in natural and cultural characteristics to classify distinct regions.
Until World War II, you could make an educated guess about a person's original home in Virginia by observing their distinctive accents, food preferences, and other patterns of behavior. Virginia's regions reflect transportation and population patterns established during the colonial era and prior to the Civil War. Physical geography shaped those patterns, and the modern regions of Virginia are still affected by features such as the Blue Ridge and the James River.
Regional boundaries are blurring, as radio/television/social media increase interaction at a national level. Today, bagels and Chinese take-out are common in Martinsville as well as Arlington, NASCAR is popular in Warrenton as well as Emporia, and Sunday afternoon football is watched in Grundy as well as Virginia Beach. In 2013, there was a Korean restaurant operating in Pembroke (Giles County) good enough to attract customers from Roanoke...
a flood control project and expansion of US460 relocated downtown Grundy across the Levisa Fork, and a Wal*Mart is now the primary retail outlet in a three-story building that replaced the distinctive old structures
There are still differences between places and people in Virginia today. If you're in a Hardee's in South Boston, notice the iced tea. Odds are, it will be sweetened, unlike the iced tea in the Hardee's at Fredericksburg. The line separating unsweetened vs. sweetened ice tea could be used to define the sections of Virginia more influenced by north culture vs. southern traditions.
Fan preferences for sports teams can also define boundaries. The Washington Redskins football team opened a sothern training camp in Richmond in 2013, in part to generate more support from that region and peel away old allegiances to teams based in Atlanta (or, more recently, in Charlottee).
In Manassas, high school students track the success of the Virginia Tech football team, but Danville students follow the athletic successes of competing universities in North Carolina. Food and music preferences offer less reliable bases for drawing sectional boundaries (there are excellent Japanese restaurants in Roanoke and Garrison Keillor has presented Prairie Home Companion shows in the coliseum there), but a Middleburg or McLean address will still carry far more social cachet - except in the West End of Richmond, where your family name may carry more weight than even your bank account.
If you have a nostalgic First Family of Virginia (FFV) perspective, you can say there's Northern Virginia and then there's "real Virginia." Typically, folks drawing this line are long-term residents who make humorous references to Northern Virginia as an alien entity, occupied Virginia filled with Northerners and people with no long-term family ties to Virginia.
In the eyes of people living far south of the Rappahannock River, Northern Virginia has been "different" ever since Lord Fairfax established a land office issuing Northern Neck deeds independently from the colonial government in Williamsburg, or Arlington was incorporated into the District of Columbia between 1800-1847.
Referring to "old Virginny" or "real Virginia" may be taken as a quaint, archaic comment when made by an elderly and wistful FFV longing for a simpler past. In the 2008 presidential election campaign, however, Republican surrogates campaigning for John McCain discovered that when non-FFV's make comments about "real Virginia," the comments may be interpreted as a put-down of modern Virginia.1
Why the strong reaction? During massive resistance to school integration/civil rights in the 1950's, advocates of perpetual segregation adopted Confederate symbols and claimed to represent the "real Virginia heritage." Today, references to "real Virginia" may be interpreted as coded language intended not just as a joke, but to express opposition to the multi-cultural diversity that is now common in urban areas and Northern Virginia.
If you are a splitter rather than a lumper, you can can segment Virginia into many, smaller cultural regions. For example, the region of Hampton Roads can be split into the Eastern Shore, Gloucester, North Hampton Roads, and South Hampton Roads. Keep splitting, and North Hampton Roads could be split into Williamsburg/York County, Newport News, and Hampton. (Poquoson has its own demographic mix, and might appreciate being omitted...) Based on political patterns, South Hampton Roads could be divided into Suffolk/Sussex/Chesapeake, Norfolk/Portsmouth, and Virginia Beach.
if you were a Census enumerator, you would try to find every single person in your Census block. However, if you were doing direct mail advertising, you would use Zip Codes to split down further all the way to distinct neighborhoods. If you were a politician, you would split down to precincts - remember, all politics is local. In a get-out-the-vote effort on election day, you would be especially granular. Your campaign would seek out supporters and independents, but try to identify and bypass the individual houses of known opponents.
The boundaries of these regions of Virginia are permeable to migration of people and information. The boundaries shown on maps appear as clear lines, but in reality regions are poorly-defined, subject to debate, and likely to be outdated within a few decades.
Loudoun and Prince William became part of Northern Virginia long after Alexandria and Arlington, and Fauquier is not yet included in most references. It's not clear if Stafford/Fredericksburg will be added to Northern Virginia, or if the megalopolis will have distict sub-regions. In a decade, cars soth of Quantico might sport FXBG stickers to identify more with Fredericksburg than with Fairfax/DC.
Northern Virginia - 1895
Since 2004, the Council on Virginia's Future has assessed the success/failure of different state-supported initiatives and programs with its "Virginia Report" scorecard, and with other reports posted on the Virginia Performs website. Accounting for the impact of government actions and future trends is presented in a statewide How Is Virginia Doing? assessment, and also in regional perspectives. The boundaries of the regions used by the Council on Virginia's Future do not match the boundaries used by the Weldon Cooper Center at the University of Virginia; even the best analysts and demographers differ in their definitions of Virginia's regions.
Even Virginia's political boundaries have been subject to change. The colonial claims to the Forks of the Ohio (Pittsburgh area) were dropped in the 1760's. Virginia's claims to the Northwest Territory (Ohio, Indiana, Illinois...) were relinquished in the 1780's. Kentucky became a separate state in the 1790's, and in the 1863 the western 33 counties of Virginia split off to become West Virginia.
George Washington considered the possibility that the United States would collapse, and split between the northern and southern states. If that had occurred, Washington planned to join the northern region.2
The two most distinctive regions of Virginia are Northern Virginia (NOVA) and Rest of Virginia (ROVA). Proposals for creating a separate State of Northern Virginia are not taken seriously today... but maybe tomorrow, sectionalism will spur another secession movement?
Boundaries of the southeastern region, known as Hampton Roads or more recently as Coastal Virginia, are also recognizable. Other efforts to define regions are less successful.
The Weldon Cooper Center for Public Service at the University of Virginia produces some of the most astute assessments of modern Virginia, but Weldon Cooper placed the city/county of Roanoke in the Valley Region which stretched north to the Potomac River. Montgomery County (including Virginia Tech) was placed in the Southwest Region, extending south to Tennessee while Franklin County was placed in the Southside Region, extending eastward to Surry County. Bedford County was placed in the Central Region, centered on Richmond. An official with the primary economic development group in Roanoke noted that economic links to the New River Valley and Bedford had been obscured by that classification system, saying:3
A more granular way to evaluate locations is the Massachusetts Institute of Technology Living Wage Calculator. It estimates the hourly earnings required to pay for basic expenses, in different locations with different costs of living. For Alleghany County in 2014, the number for an individual was $7.49/hour, in Roanoke city and county it was $8.49/hour, while in most of Northern Virginia it was $13.22/hour.4
