There must be at least 40 Springfields in the USA. Given Massachusetts's early statehood, I wouldn't be surprised if Springfield, MA was the "first" Springfield in USA, but are you thinking the artist illustrated all the Springfields because of the Simpsons?

Suddenly I have an urge to make a Voronoi map of the US using each Springfield as the capital of its own state.

It’s the first, largest and (unfortunately) poorest Springfield.

(I’m writing this from Springfield right now)

Springfield MO is larger. About as poor, but Springfield MA ekes that out still.

Yep, you’re correct, I was using old numbers - Springfield MA lost some population while Springfield MO grew. But we still have Dr. Suess!
