Fairfax County is a
county in
Northern Virginia, in the
United States. , the estimated population of the county is 1,015,302, making it by far the most populous jurisdiction in the Commonwealth of Virginia, and the most populous jurisdiction in the
Washington Metropolitan Area. Fairfax was the first county to reach a six-
figure median household income, and has the second-
highest median household income of any jurisdiction in the United States after neighboring
Loudoun County.
As of 2007, 14% of Virginia's population was located in Fairfax County, making it the most populous county in Virginia.
History
Fairfax County was formed in 1742 from the northern part of
Prince William County. It was named for
Thomas Fairfax, 6th Lord Fairfax of Cameron (1693–1781), proprietor of the
Northern Neck.
The oldest settlements in Fairfax County were located along the
Potomac River.
George Washington settled in Fairfax County and built his home,
Mount Vernon, facing the river.
Gunston Hall, the home of
George Mason is located nearby. Modern
Fort Belvoir is partly located on the estate of Belvoir Manor, built along the Potomac by William Fairfax in 1741.
Thomas Fairfax, 6th Lord Fairfax of Cameron, the only member of the British nobility ever to reside in the colonies, lived at Belvoir before he moved to the
Shenandoah Valley. The Belvoir mansion and several of its outbuildings were destroyed by fire immediately after the
Revolutionary War in 1783, and George Washington noted the plantation complex gradually deteriorated into ruins.
In 1757, the northwestern two-thirds of Fairfax County became
Loudoun County. In 1789, part of Fairfax County was ceded to the federal government to form
Alexandria County of the
District of Columbia. Alexandria County was returned to Virginia in 1846, reduced in size by the secession of the
independent city of
Alexandria in 1870, and renamed
Arlington County in 1920. The Fairfax County town of
Falls Church became an independent city in 1948. The Fairfax County town of
Fairfax became an independent city in 1961.
Located near Washington, D.C., Fairfax County was an important region in the
Civil War. The
Battle of Chantilly or Ox Hill, during the same campaign as the
second Battle of Bull Run, was fought within the county; Bull Run straddles the border between Fairfax and Prince William County. For most of the Civil War,
Union troops occupied the county, though the population remained sympathetic to the
Confederacy.
The growth of the federal government in the years during and after World War II spurred rapid growth in the county. As a result, the once rural county began to become increasingly suburban. Other large businesses continued to settle in Fairfax County and the opening of
Tysons Corner Center spurred the rise of
Tysons Corner itself. The technology boom and a steady government-driven economy also created rapid growth and an increasingly growing and diverse population. The economy has also made Fairfax County one of the wealthiest counties in the nation.
Geography

Map of Fairfax County and neighboring jurisdictions
Fairfax County is bounded on the north and southeast by the
Potomac River. Across the river to the northeast is
Washington, D.C., across the river to the north is
Montgomery County, Maryland, and across the river to the southeast are
Prince George's County, Maryland and
Charles County, Maryland. The county is partially bounded on the north and east by
Arlington County and the independent cities of
Alexandria and
Falls Church. It is bounded on the west by
Loudoun County, and on the south by
Prince William County.
According to the
U.S. Census Bureau, the county has a total area of 407 square miles (1,053 km²), of which, 395 square miles (1,023 km²) of it is land and 12 square miles (30 km²) of it (2.85%) is water.

Geology
Eleven square miles of the county are known to be underlain with natural
asbestos. Much of the asbestos is known to emanate from fibrous
tremolite or
actinolite. Approximately 20 years ago, when the threat was discovered, the county established laws to monitor air quality at construction sites, control soil taken from affected areas, and require freshly developed sites to lay of clean, stable material over the ground.
For instance, during the construction of
Centreville High School a large amount of asbestos-laden soil was removed and then trucked to Vienna for the construction of the I-66/Nutley Street interchange. Fill dirt then had to be trucked in to make the site level.
Marine clays can be found in widespread areas of the county east of Interstate 95, mostly in the Lee and Mount Vernon districts. These clays contribute to soil instability, leading to significant construction challenges for builders.
Government and politics
The county is governed by a
Board of Supervisors, composed of nine members elected from single-member districts and a chairman elected at-large. The districts are named Braddock, Dranesville, Hunter Mill, Lee, Mason, Mount Vernon, Providence, Springfield, and Sully.
Fairfax County's Government Center is west of the City of Fairfax in an
unincorporated area. Fairfax County contains an
exclave unincorporated area located in the central business district of the City of Fairfax, in which many county facilities (including the courthouses and jail) are located.
["." U.S. Census Bureau. Retrieved on April 4, 2009.]["." Fairfax County. Retrieved on April 4, 2009.]Fairfax County was once considered a strong
Republican bastion in the suburbs of
Washington, D.C. However,
Democrats have in the past decade made significant inroads, gaining control of the Board of Supervisors and the School Board (officially nonpartisan) as well as the offices of
Sheriff and
Commonwealth Attorney. Democrats also control the majority of Fairfax seats in the Virginia
House of Delegates and
Senate.
Following the
election of November 2008, Republicans hold just one of the three congressional seats that include parts of Fairfax County. Communities closer to Washington, D.C. generally favor Democrats by a larger margin than do the outlying communities. In elections in 2000, 2001, and 2005, Fairfax County supported Democrats for U.S. Senate and governor. In 2004,
John Kerry won the county, becoming the first Democrat to do so since
Lyndon B. Johnson in his 1964 landslide (the last time Democrats carried the state until 2008). Kerry defeated
George W. Bush in the county 53% to 46%.
Democratic Governor
Tim Kaine carried Fairfax County with over 60% of the vote in 2005, leading him to win 51.7% of votes statewide. On November 7, 2006, U.S. Senator
Jim Webb (D) carried the county with about 58.9% of the votes.
In the state and local elections of November 2007, Fairfax Democrats picked up one seat in the
House of Delegates, two seats in the
Senate, and one seat on the Board of Supervisors, making their majority there 8-2.
On November 4, 2008, Fairfax County continued its shift towards the Democrats, with
Barack Obama and
Mark Warner each garnering over 60% of the vote for president and U.S. Senate, respectively. Also, the Fairfax-anchored 11th District United States House of Representatives seat held by
Thomas M. Davis for 14 years was won by
Gerry Connolly, the Democratic Chairman of the Fairfax County Board of Supervisors.
Braddock supervisor
Sharon Bulova won a special election on February 3, 2009 to succeed
Gerry Connolly as chairman of the Board of Supervisors, continuing a Democratic hold on the office of chairman that dates back to 1995. In November, 2009, Governor-elect Bob McDonnell won Fairfax County with 51% of the vote.

Judged by household median income, Fairfax County is among the
highest-income counties in the country, and was first on that list for many years. However, in the 2000 census it was overtaken by
Douglas County, Colorado. According to U.S. Census Bureau estimates for 2005, it had the second-highest median household income behind neighboring Loudoun County, at $94,610. In 2007, Fairfax County reclaimed its position as the richest county in America, in addition to becoming the first jurisdiction in American history to have a median household income in excess of $100,000. In 2008, Loudoun County reclaimed the first position, with Fairfax County a close second (although the U.S. Census Bureau notes that the difference is statistically insignificant).

The school system has estimated that, based on the 2008 fiscal year budget, the county will be spending $13,407 on each student.
The Fairfax County Public School system contains the
Thomas Jefferson High School for Science and Technology, a Virginia Governor's School. TJHSST consistently ranks at or near the top of all United States high schools due to the extraordinary number of National Merit Semi-Finalists and Finalists, the high average SAT scores of its students, and the number of students who annually perform nationally recognized research in the sciences and engineering.
