Louisville metropolitan area


The Louisville metropolitan area or Kentuckiana, also known as the Louisville–Jefferson County, Kentucky–Indiana, metropolitan statistical area, is the 45th largest metropolitan statistical area in the United States. The principal city is Louisville, Kentucky.
It was originally formed by the United States Census Bureau in 1950 and consisted of the Kentucky county of Jefferson and the Indiana counties of Clark and Floyd. As surrounding counties saw an increase in their population densities and the number of their residents employed within Jefferson County, they met Census criteria to be added to the MSA. Jefferson County, Kentucky, plus twelve outlying countiesseven in Kentucky and five in Southern Indianaare now a part of this MSA. One other Kentucky county was part of the MSA in the 2000 and 2010 U.S. Censuses, but was spun off by the Census Bureau into its own Micropolitan Statistical Area in 2013.
People living in any of the MSA are said to be living in the Louisville–Jefferson County Area. Because it includes counties in Indiana, the MSA is regularly referred to as Kentuckiana. It is now the primary MSA of the Louisville/Jefferson County–Elizabethtown–Bardstown, KY-IN Combined Statistical Area. The combined statistical area created by the United States Bureau of the Census in 2000 and most recently redefined in 2018 comprises the Louisville–Jefferson County MSA, the Elizabethtown–Fort Knox, Kentucky, MSA, the Bardstown, Kentucky, micropolitan statistical area and the Scottsburg, Indiana micropolitan statistical area.

Definitions

the U.S. Office of Management and Budget defines the Louisville–Jefferson County MSA as including Bullitt, Henry, Jefferson, Meade, Oldham, Shelby, and Trimble Counties in Kentucky and Clark, Floyd, Harrison, Scott, and Washington Counties in Indiana. The larger Louisville–Jefferson County–Elizabethtown–Bardstown CSA adds two other statistical areas in Kentucky and one in Indiana:

Madison, Indiana, µSA
Principal city
In 2003, the Jefferson government merged with that of its largest city and county seat, Louisville, forming a new entity, the Louisville–Jefferson County Metro Government or Louisville Metro. All small cities within Jefferson became part of the new Louisville Metro government while retaining their city governments. For statistical and ranking purposes, the United States Census Bureau uses the statistical entity Louisville–Jefferson County metro government, Kentucky, to represent the portion of the consolidated city-county of Louisville–Jefferson County that does not include any of the 83 separate incorporated places located within the city and county.
