1 in 4 Comics Readers is a Senior Citizen
The truth is that for a few decades now, the average age of the comics reader has been rising. Many feel that 40 year old men have made up the bulk of comics readership for the last twenty years. And, of course, there's that fact that in comics' heyday, almost everyone read comics. In other cultures, sequential art is enjoyed by multiple segments of the population as well.
To further attempt halting the concept of comics as youth culture, consider that Simba Publishing just releases a report stating that 1 in 4 comics readers is over 65 years old.
As the press release reads, "Despite notable efforts from many in the industry, comics and graphic novels continue to be repeatedly mislabeled as just another children’s book category,” said Warren Pawlowski, online publishing manager for Simba Information and an analyst within the company’s Trade Books Group. “With nearly a quarter of the comic reading audience beyond the age of retirement, there is a misconception that needs to be corrected.”
Yep. Or should I say, Yessiree! Also see here for a broader overview of the comics and GN market. If you have the Benjamins, that is! (You'll see what I mean)
