The region has been increasing slowly thanks to steady job growth, a low cost of living and affordable home prices.

The Louisville area was chosen as a settlement because it is located at the Falls of the Ohio State Park, which created a barrier to river travel. The first European settlement was Corn Island in 1779. Two years later, the town charter for Louisville was approved, and the city was named in honor of King Louis XVI of France, whose soldiers were then helping Americans in the Revolutionary War. Early residents eventually moved out by the 1780s due to Indian raids.
The city's growth in the 1800s was influenced by the fact that river boats had to unload and move downriver before reaching the falls. By 1828, the population reached 7,000, and the city was incorporated. It became a shipping port, and it was known as a point of escape for slaves moving north. It was also a stronghold for Union troops during the Civil War.
During World War II, Louisville became a center for factory war production, which later transitioned into manufacturing tractors and agricultural equipment. Like many other older cities in the country, the population began to shift in the 1960s as more people fled to the suburbs.
