What does "The Middle" refer to in the TV show The Middle? I thought it referred to one of the kids being the middle child before I watched it, but that's obviously not correct.
The show is set in Indiana, and the title is trying to evoke the idea that this is a fun, "meat and potatoes" family sitcom that represents "middle" America (i.e. it's not New York, it's not California, it's not the South ... just the "Heartland").
Here's a "TV Tropes" link that can really do a better job answering your question than me: Flyover Country
I think there's also a secondary nod to the economic, "middle class" suburban community depicted on the show.
In Czech, the series' name is translated as Průměrňákovi (The Averages). I think it correctly describes the fact that the Hecks are not very successful in their lives (especially Sue I would say). Of course, a lot of their problems are caused by the Hecks themselves, for example when they are not paying their bills.
