Context paragraphs:
Lynchburg, Tennessee: Lynchburg is a city in the south-central region of the U.S. state of Tennessee.  It is governed by a consolidated city-county government unit whose boundaries coincide with those of Moore County.  Lynchburg is best known as the location of Jack Daniel's, whose famous Tennessee whiskey is marketed worldwide as the product of a city with only one traffic light.  Despite the operational distillery, which is a major tourist attraction, Lynchburg's home county of Moore is a dry county.  The population was 6,362 at the 2010 census.

Muscogee County, Georgia: Muscogee County is a county located on the central western border of the U.S. state of Georgia; its western border with the state of Alabama is formed by the Chattahoochee River.  As of the 2010 census, the population was 189,885.  Its county seat and only city is Columbus, with which it has been a consolidated city-county since the beginning of 1971.

Mayor of San Francisco: The Mayor of the City and County of San Francisco is the head of the executive branch of the San Francisco city and county government.  The mayor has the duty to enforce city laws, and the power to either approve or veto bills passed by the San Francisco Board of Supervisors, the legislative branch.  The mayor serves a four-year term and is limited to two successive terms.  Because of San Francisco's status as a consolidated city-county, the mayor also serves as the head of government of the county; both entities have been governed together by a combined set of governing bodies since 1856.

Government of Louisville, Kentucky: The government of Louisville, Kentucky, administers Louisville Metro, a consolidation of the pre-2003 areas known as the City of Louisville and surrounding Jefferson County.  It operates a unified mayor–council government, with an executive called the Mayor of Louisville Metro or "Metro Mayor" and a city council called the Louisville Metro Council or "Metro Council".  Their administration oversees most of the responsibilities of both the former city and county; notable exceptions are the offices of County Clerk and Sheriff, which continue to operate separately due to continuing state constitutional requirements.  Formed on January 6, 2003, Louisville Metro was the second such consolidated city-county government in the Commonwealth to form since Lexington, which merged with surrounding Fayette County in 1974.

WBKZ (defunct): WBKZ (880 AM) was a radio station licensed to Jefferson, Georgia, USA, and serving the Athens area.  The station is currently owned by Brown Broadcasting System, Inc.

Hawaii's 1st congressional district: Hawaii's 1st congressional district is a congressional district in the U.S. state of Hawaii.  The district is located entirely on the island of Oahu, encompassing the urban areas of the City and County of Honolulu, a consolidated city-county that includes Oahu's central plains and southern shores, including the towns of Aiea, Mililani, Pearl City, Waipahu and Waimalu.  The district is smaller and more densely populated than the 2nd Congressional District (which includes the rest of the state).  It is the only majority-Asian district in the United States.

Kansas City, Kansas: Kansas City is the third-largest city in the state of Kansas, the county seat of Wyandotte County, and the third-largest city of the Kansas City metropolitan area.  Kansas City, Kansas is abbreviated as "KCK" to differentiate it from Kansas City, Missouri.  It is part of a consolidated city-county government known as the "Unified Government".  Wyandotte County also includes the independent cities of Bonner Springs and Edwardsville.  As of the 2010 census, the city had a population of 145,786 residents.  It is situated at Kaw Point, which is the junction of the Missouri and Kansas rivers.

List of cities in Indiana: Indiana is a state located in the Midwestern United States.  As of the 2016 census estimate, the state had 6,633,053 residents.  Except as noted, all cities are "third-class" cities with a seven-member city council and an elected clerk-treasurer.  "Second-class" cities had a population of at least 35,000 and up to 600,000 at time of designation, and have a nine-member city council and an elected clerk.  Indianapolis is the only "first-class" city in Indiana under state law, making it subject to a consolidated city-county government known as Unigov.  To become a city of any class, however, a settlement must have a population of at least 2,000.

Athens, Georgia: Athens (formally known as Athens-Clarke County) is a consolidated city–county in the U.S. state of Georgia, in the northeastern part of the state about an hour's drive from the global city of Atlanta, and comprising the former city of Athens proper (the county seat) and Clarke County.  The University of Georgia, the state's flagship public research university, is located in this college town, and contributed to its initial growth.  In 1991, after a vote the preceding year, the original city abandoned its charter to form a unified government with Clarke County, referred to jointly as Athens-Clarke County.  As of the 2010 census, the consolidated city-county (including all of Athens-Clarke County except Winterville and a portion of Bogart) had a total population of 115,452; all of Clarke County had a population of 116,714.  Athens is the sixth-largest city in Georgia, and the principal city of the Athens-Clarke County, Georgia Metropolitan Statistical Area, which had a population of 192,541 as of the 2010 census.  Athens-Clarke County has the smallest geographical area of a county in Georgia.
