'The Simpsons': Matt Groening reveals the real SpringfieldAdd to Favorites | The Simpsons
In an interview with Smithsonian magazine, Groening says that the wildly popular animated show takes place in Springfield, OR, a city about 110 miles south of his hometown of Portland.
"Springfield was named after Springfield, Oregon. The only reason is that when I was a kid, the TV show 'Father Knows Best' took place in the town of Springfield, and I was thrilled because I imagined that it was the town next to Portland, my hometown," Groening says. "When I grew up, I realized it was just a fictitious name. I also figured out that Springfield was one of the most common names for a city in the U.S. In anticipation of the success of the show, I thought, 'This will be cool; everyone will think it's their Springfield.' And they do."
There have been obvious hints that the Oregon town of just under 60,000 was the likely inspiration. In addition to similarities in geography, topography and weather, the most notable reference is the nuclear power plant that Homer works at. It is long believed that this was modeled after the former Trojan nuclear plant in Rainier, OR, a town 50 miles north of Portland.
So now that you know where Homer, Marge, Bart, Lisa and Maggie live, here's a little more information about their real-life town:
Total Area: 14.4 sq. mi.
Annual High temperature: 63 degrees
