The capital, Frankfort, lies between the two major cities—Louisville, which is on the Ohio River, and Lexington. From the beginning, Kentucky has been a strongly rural state of small towns and crossroads. In the early 21st century about half of the state’s population remained rural, despite pronounced migration from rural to urban areas in the second half of the 20th century. The three areas that have the largest populations are the cities of Louisville and Lexington and the portion of northern Kentucky that includes Covington and Newport, both situated just opposite Cincinnati on the Ohio River. Together, these three population centres form the points of the so-called “Golden Triangle,” an economic region that is home to more than half of Kentucky’s people. Notable among Kentucky’s smaller cities are Ashland, Bowling Green, Paducah, Owensboro, and Frankfort.
