Cobb County is a suburban county located in the U.S. state of Georgia. Its county seat and largest city is Marietta, which is located in the center of the county. The county was named for Thomas Willis Cobb, who in the early 19th century was a United States representative and senator from Georgia. It is believed that Marietta was named for his wife, Mary.
Cobb, along with several adjoining counties, was created on December 3, 1832, by the Georgia General Assembly from the huge Cherokee "county" territory — land northwest of the Chattahoochee River which the state confiscated from the Cherokee Nation and redistributed to settlers via lottery, following the passage of the federal Indian Removal Act.
As of the 2010 census, the population was 688,078. The county's population has continued to grow. It is a part of the five-county Atlanta metropolitan area. Cobb County is situated immediately outside the northwest city limits of Atlanta, and is connected to the metropolitan area by interstate highways I-285, I-75, I-20 and I-575. In the last three decades of the 20th century, the county was one of the fastest growing areas of the United States. Within the past 50 years, the county has grown from a primarily undeveloped rural area into a metropolitan suburb.
The U.S. Census Bureau ranks Cobb County as the most-educated in the state of Georgia and 12th among all counties in the United States.[dead link] It has ranked among the top 100 wealthiest counties in the United States.
According to the 2000 census, the county has a total area of 344.51 square miles (892.3 km2), of which 340.15 square miles (881.0 km2) (or 98.73%) is land and 4.36 square miles (11.3 km2) (or 1.27%) is water.
The county is divided between two major basins. Most runoff flows into the Chattahoochee River along the southeastern border, directly via Willeo Creek, Sope Creek (Sewell Creek), Rottenwood Creek (Powers Creek), and others. The large Sweetwater Creek is the other major stream, carrying the waters of Noses Creek (Ward Creek, Olley Creek, and Mud Creek), Nickajack Creek, Powder Springs Creek (Rakestraw Creek, Mill Creek) and others into the Chattahoochee. A ridge from Lost Mountain in the west, to Kennesaw Mountain in the north-central, to Sweat Mountain in the extreme northeast, divides the far north-northwest of the county into the Etowah River basin, which includes Lake Allatoona. Noonday Creek (Little Noonday Creek) flows northward into the lake, as does Allatoona Creek, which forms a major arm of the lake. Proctor Creek forms the much older Lake Acworth, which in turn empties directly into Lake Allatoona under the Lake Acworth Drive (Georgia 92) bridge.
There are several high points in Cobb County.
- Sweat Mountain, in the extreme northeast portion, runs along the border with Cherokee County, and is the metro area's major antenna farm
- Blackjack Mountain, a low ridge between central and east Cobb
- Kennesaw Mountain: the highest point in the county and in the entire suburban area of metro Atlanta, located in the north-northwest between Kennesaw and Marietta
- Little Kennesaw Mountain: an offshoot of Kennesaw
- Lost Mountain, in western Cobb
- Pine Mountain, west-northwest of Kennesaw Mountain, between Kennesaw and Due West
- Brushy Mountain, near Kennesaw Mountain, just southeast of Barrett Parkway at Cobb Parkway
- Vinings Mountain or Mount Wilkinson, overlooks the town of Vinings

Geocodes & World's largest toll-free calling area 
Originally in area code 404, the county was moved into area code 770 in 1995, and overlaid by area code 678 in 1998. Prior to 1995, those with phones tied to the Woodstock telephone exchange (prefixes 924, 926, 928, later 516 and 591) could also call the Canton exchange (479, later 445, then 704) as a local call. This became moot, along with other dual-zone exchanges in metro Atlanta, when the exurban exchanges (including Canton) were fully made a part of what was already the world's largest toll-free calling zone. It is a zone spanning 7,162 square miles (18,549 km2), with four active telephone area codes, and local calling extending into portions of two others.
Cobb's FIPS county code is 13067. Because the National Weather Service has not subdivided the county, its WRSAME code is 013067, for receiving targeted weather warnings from NOAA Weather Radio. The county is primarily within the broadcast range of one weather radio station: KEC80, on 162.550 MHz, transmitted to all of metro Atlanta and broadcast from NWSFO Peachtree City. The secondary station is the much newer WWH23 on 162.425 from Buchanan, which also transmits warnings for Cobb but has reception mainly in the western part of the county.
Cobb County was one of nine Georgia counties carved out of the former Cherokee Indian Nation in 1831, after the Trail of Tears. It was the 81st county in Georgia and named for Judge Thomas Willis Cobb, who served as a U.S. Senator, state congressman and Superior Court Judge. It is believed that the county seat of Marietta was named for Judge Cobb's wife, Mary.
In the antebellum era, Marietta was a summer resort for residents of Savannah and Charleston fleeing Yellow Fever. During the American Civil War, the Battle of Kennesaw Mountain June 27 was the site of the only major Confederate victory in Gen. William T. Sherman's invasion of Georgia in 1864. Nevertheless, Union forces outflanked the Confederates.
There were battles of New Hope Church May 25, Pickett's Mill May 27, and Dallas May 28. The Battle of Allatoona Pass on October 28 occurred as Sherman was starting his March through Georgia. Union forces burnt most houses and confiscated or burnt crops.
In 1915, Leo Frank, the Jewish supervisor of an Atlanta pencil factory who was convicted of murdering one of his workers, thirteen-year-old Mary Phagan, was kidnapped from his jail cell and brought to Frey's Gin, two miles (3 km) east of Marietta. There he was lynched. The case was widely perceived as a miscarriage of justice.
In 1942, Bell Aircraft opened a Marietta plant to manufacture B-29 bombers and Marietta Army Airfield was founded. Both were closed after World War II, but reopened during the Korean War, when the air field was acquired by the Air Force, renamed Dobbins AFB, and the plant by Lockheed. During the Korean and Vietnam Wars, Lockheed Marietta was the leading manufacturer of military transport planes, including the C-130 Hercules and the C-5 Galaxy. "In Cobb County and other sprawling Cold War suburbs from Orange County to Norfolk/Hampton Roads, the direct link between federal defense spending and local economic prosperity structured a bipartisan political culture of hawkish conservatism and material self-interest on issues of national security."
When home rule was enacted statewide by amendment to the Georgia state constitution in the early 1960s, Ernest W. Barrett became the first chairman of the new county commission. The county courthouse, built in 1888, was demolished.
In the 1960s and 1970s, Cobb transformed from rural to suburban, as integration spurred white flight from the city of Atlanta, which by 1970 was majority-African-American. Real estate booms drew rural white southerners and Rustbelt transplants, both groups mostly first-generation white-collar. Cobb County was the home of former segregationist and Georgia governor Lester Maddox (1966–71). In 1975, Cobb voters elected John Birch Society leader Larry McDonald to Congress, running in opposition to desegregation busing. A conservative Democrat, McDonald called for investigations into alleged plots by the Rockefellers and the Soviet Union to impose 'socialist-one-world-government' and co-founded the Western Goals Foundation. In 1983, McDonald died aboard Korean airlines flight 007, shot down by a Soviet fighter over restricted airspace.
In 1990, Republican Congressmen Newt Gingrich became Representative of a new district centered around Cobb County. In 1994, as Republicans took control of the House of Representatives for the first time in almost fifty years, Gingrich became Speaker of the House, thrusting Cobb County into the national spotlight. In 1993, county commissioners passed a resolution condemning homosexuality and cut off funding for the arts after complaints about a community theater. After protests from gay rights organizations, organizers of the 1996 Olympics pulled events out of Cobb County.
In the 1990s and 2000s, Cobb's demographics changed. As Atlanta's gentrification reversed decades of white flight, middle-class African-Americans and Russian, Bosnian, Chinese, Indian, Brazilian, Mexican and Central American immigrants moved to older suburbs in South and West Cobb. In 2010, African-American Democrat David Scott was elected to Georgia's 13th congressional district, which included many of those suburbs. Cobb became the first Georgia county to participate in the Immigration and Nationality Act Section 287(g) enabling local law officers to enforce immigration law.
As of 2011, there were 697,553 people, 248,303 households, and 169,178 families residing in the county. The population density was 1,998 people per square mile (763/km²).

Government and elections 
Under Georgia's home rule provision, county governments have free rein to legislate on all matters within the county, provided that such legislation does not conflict with state or federal laws or constitutions.
Cobb County is governed by a five-member board of commissioners, which has both legislative and executive authority within the county. The chairman of the board is elected county-wide. The other four commissioners are elected from single-member districts. The board hires a county manager who oversees day-to-day operations of the county's executive departments.
County residents also elect a sheriff, district attorney, probate court judge, clerk of superior court, clerk of the state court, state court solicitor, chief magistrate judge (who then appoints other magistrate court judges), superior court judges, state court judges, tax commissioner, surveyor, and a seven-member board of education. In addition to the county sheriff, the constitutional chief law enforcement officer of the county, Cobb County has a separate police department under the authority of the Board of Commissioners. The sheriff oversees the jail, to which everyone arrested under state law is taken, regardless of the city or other area of the county where it happens, or what police department makes the arrest.
Each city has a separate police department, answerable to its governing council. Marietta, Smyrna, and Austell have separate fire departments, with the Cobb County Fire Department being the authority having jurisdiction over Kennesaw, Acworth, Powder Springs, and unincorporated areas. Cobb 911 covers unincorporated areas and the cities of Marietta and Powder Springs. Kennesaw and Acworth jointly operate a small 911 call center (PSAP) upstairs in Kennesaw city hall, dispatching the police departments in both cities, and forwarding fire calls to Cobb. Austell and Smyrna operate their own separate 911 systems.
The county retails potable water to much of the county, and wholesales it to various cities.
In addition to the 4% statewide sales tax, Cobb County levies an additional 2% for special projects, each 1% subject to separate renewal every few years by countywide referendum (including within its cities). This funds mainly transportation and parks. Cobb levies a 1% tax to lower property taxes, but only for the public school budget, and not the additional 1% HOST homestead exemption for general funds. It has also voted not to pay the extra 1% to join MARTA.
At the beginning of 2006, Cobb County became the last county in the state to raise the tax to 6%, which also doubled the tax on food to 2%. The SPLOST barely passed by a 114 vote margin, or less than one-quarter of a percent, in a September 2005 referendum. The revenue will go to a new county courthouse, expanded jail, various transportation projects, and the purchasing of property for parks and green space. In 2008, the school tax was renewed for a third term, funding the Marietta and Cobb school systems.
