Where Is Springfield on "The Simpsons?"

So, I’m sure you’ve watched or at least heard of the cartoon The Simpsons. If you don’t, FYI, it’s the longest-running cartoon on American prime-time network television (1989).

Anyways, one of the most disputed questions about The Simpsons is: What state does the show take place in? The cartoon clearly indicates it’s in the city of Springfield. However, there are 53 Springfields in 34 states.

Which real Springfield is the model for the Springfield on "The Simpsons?" Here are some clues:

Many fans say "Behind the Laughter" definitvely noted that Springfield was in Kentucky, per the narrator. But in repeats of that episode, the narrator said Springfield was in Missouri.

* Notice that Homer's driver's license reads Springfield, NT 49007

*Remember that Springfield has its own international airport.

*Homer's social security number is 568-47-0008. Social security numbers that begin with 568 are typically issued in California.

*In "Mr. Lisa Goes To Washington," Springfield's congressman, Bob Arnold, is approached by two different shady corporate types and offered bribes, firstly to cut down Springfield's National Forest, and secondly, later in the episode, to drill for oil on Mount Rushmore. This places Springfield firmly in South Dakota.

*Springfield has its own docks and beach.

What do these clues all mean? There are so many geographical contradictions between episodes that it is impossible for Springfield to actually exist somewhere real. Even the creator himself (Matt Groening) has said he chose the name "Springfield" simply because it is one of the most common city names in the United States.
