In reality, this is a line of land mass that makes up about a third of the Commonwealth's land mass as well as over half of its population. It runs from Henderson County on the far west end, and all the way to Maysville on the far east end, both of them along the Ohio River. The major metropolises, medium-sized cities, and large towns in this area include Henderson, Owensboro, Elizabethtown, Madisonville (not far from the South), Louisville, Frankfort, Lexington, Florence, Covington, Newport, and Maysville. This large land strip is the Midwestern part of Kentucky; everything below, including Bowling Green, Paducah, Glasgow, Somerset, and Richmond, is the Southern part of Kentucky.
The people of Northern Kentucky are not too much different from those in the rest of the Commonwealth. Most of us have the same morals, religion, and even politics. The only differences are we have more connections with the "official" Northern states, and therefore do more business with them; we also have more Northern regional and cultural influences, especially from Ohio and Indiana. That is why many of the North Kentuckians act and sometimes talk more like Northerners.
The region of land that separates the city of Cincinnati from the state of Kentucky. The residents of this area always stress their proximity to Ohio and always make sure to point out that Northern Kentucky is unlike the rest of the state. However, this ares is in a way its own state. The Ohioans refuse to accept it since it is part of Kentucky, and the rest of Kentucky considers residents of this area to be "damnyankees".
I live in Northern Kentucky but I just tell people I'm from Cincinnati.
