The Simpsons' characters are trapped in a universe where life is static, but if they did get old normally, their current ages might surprise fans. The Simpsons is a show that's always thrived on keeping its continuity very loose, with changes to the characters' lives only rarely becoming permanent, such as the death of Maude Flanders or Milhouse's parents getting divorced. Otherwise, both the titular family and their friends and neighbors exist in a sort of stasis, in which things almost always return to status quo.

In some ways, this decision has been a creative boon to The Simpsons, as the show's central character dynamics have rarely had to change, allowing fans to feel a sense of consistency during such a long run on the air. On the other hand, this setup also doesn't really allow for much character development, with people like Bart and Homer having learned the same lessons repeatedly over the course of the series.

Without any further ado, here's our assessment of how old the Simpson family would be had they aged normally, based on information presented within the series. It's almost impossible to reach a conclusion everyone will agree on though, as later seasons have moved things like Homer and Marge's courtship and the birth of their children into later decades than they were originally placed.

As mentioned, the Simpsons' ages are very hard to pin down, although Homer's isn't quite the hardest. His age has been stated to range between 34 and 40 onscreen, depending on the season. However, the biggest piece of evidence to go on comes during season 4, which features a brief look at Homer's driver's license. The listed birthdate is May 12, 1956, meaning he turned 64 in 2020, and is officially a senior citizen.

Marge Simpson's Age

Marge's age has also been placed anywhere in the 34-40 range over the course of The Simpsons series. Sadly, Marge's age is a lot harder to narrow down than Homer's, as an actual number has been mentioned less frequently, and the show has also said her birthday is in both May and October, depending on the season. However, in The Simpsons' first flashback episode, "The Way We Was," Homer and Marge are shown as high school seniors at the same time. This suggests Marge is also 64.

Bart Simpson's Age

Bart's age is a bit easier to take a swing at hitting, as Bart actually had a birthday officially take place onscreen. Bart turned 10 in the season 3 episode "Radio Bart," and has always canonically been 10 since, making him 38-years-old as of 2020.

Lisa Simpson's Age

Lisa, like Bart, also had a canonical birthday onscreen, in the season 3 episode "Stark Raving Dad," which gave birth to the famous "Lisa, It's Your Birthday" song. She turned 8 in that episode, and has been 8 on the show since, and since she's been stated to be slightly over 2 years younger than Bart, she's 36 as of 2020.

Maggie Simpson's Age

Maggie also celebrates a birthday onscreen, although in an example of The Simpsons' strange timeline, hers happened in season 5, during the episode "Lady Bouvier's Lover." She turns 1 in that episode, which would theoretically make her 26 in 2020. However, she's been 1 ever since, and if she exists as a 1-year-old alongside 10-year-old Bart and 8-year-old Lisa, Maggie is mostly likely 29.
