The Commonwealth of Kentucky is a state located in the East Central United States, normally included in the group of Southern states, but sometimes partially included, geographically and culturally, in the Midwest. Kentucky is one of four U.S. states established as a commonwealth. Originally a part of Virginia, in 1792 it became the 15th state to join the Union. Kentucky is the 37th largest state in terms of land area, and ranks 26th in population.
More than half of Kentucky's population and over 80% of the state's population growth are concentrated in what is referred to as the Golden Triangle, framed by Louisville, Lexington and the suburban Northern Kentucky region. The capital is Frankfort and the largest city is Louisville.
Kentucky is known as the "Bluegrass State," a nickname based on the fact that bluegrass is present in many of the lawns and pastures throughout the state. It is a land with diverse environments and abundant resources. It has expansive cave and karst systems, coalfields, wetlands and forests. Kentucky is also known for thoroughbred horses, horse racing, bourbon whisky distilleries, bluegrass music, and college basketball.
