List of counties in Kentucky
There are 120 counties in the U.S. Commonwealth of Kentucky. Despite ranking 37th in size by area, Kentucky has 120 counties, fourth among states (including Virginia's independent cities). The original motivation for having so many counties was to ensure that residents in the days of poor roads and horseback travel could make a round trip from their home to the county seat in a single day, as well as being able to travel from one county seat to the next in the same fashion. Later, however, politics began to play a part, with citizens  who disagreed with their county government petitioning the state to create a new county. Today, 21 of the 120 counties have fewer than 10,000 residents, and half have fewer than 20,000. The 20 largest counties by population all have populations of 48,000 or higher. The average county population, based on the estimated 2021 state population of 4.509 million, was 37,578. Following concerns of too many counties, the 1891 Kentucky Constitution placed stricter limits on county creation, stipulating that a new county: These regulations have reined in the proliferation of counties in Kentucky. Since the 1891 Constitution, only McCreary County has  been legally created, in 1912. The General Assembly's creation of Beckham County in 1904 was ruled unconstitutional. Because today's largest county by area, Pike County, is , it is only still possible to form a new county from portions of more than one existing county; McCreary County was formed in this manner, from parts of Wayne, Pulaski and Whitley counties. Kentucky was originally a single county in Virginia, created in 1776. In 1780, Kentucky County was divided into Fayette, Jefferson, and Lincoln counties. Kentucky was admitted as a state in 1792, when it had nine counties. Each county has  a legislative council called the fiscal court; despite the name, it no longer has any responsibility for judicial proceedings. The county judge/executive, the head of government of the county, is an "ex officio" member of the fiscal court and its presiding officer. Constitutionally, the fiscal court may either be composed of the magistrates for the county or of three commissioners elected from the county at large. The largest city in Kentucky, Louisville, is a consolidated local government under KRS 67C. When the Louisville Metro government was formed, all incorporated cities in Jefferson County, apart from Louisville, retained their status  as cities; however, the Louisville Metro Council is the main government for the entire county, and is elected by residents in all of Jefferson County. The second largest, Lexington, is an urban-county government under KRS 67A. Lexington and Fayette County are completely merged and there are no separate incorporated cities within the county. In both of these counties, while Lexington and Louisville city governments govern their respective counties, a county judge/executive is still elected, as required by Kentucky's Constitution, but does not have substantive powers. The Federal Information Processing Standard (FIPS) code, which is used by the  United States government to uniquely identify counties, is provided with each entry; for Kentucky, the codes start with 21 and are completed with the three digit county code. The FIPS code for each county links to census data for that county. Clickable map.
