Yeah, I think some artists create characters with an age near your age. It looks to be more comfortable to build the characters personality, because we are simply living in this life period.
I have 18 years old now.
"Team Trouble" it's about me and my friends, so it doesn't count.
The concept and the characters from "The Sky Travelers1" I created when I was 17. They are:
Hiraku Saitou - 18yo
Kotone Minami - 17yo
Hiroshi Tanaka - 17yo
Ryoko Aikawa - 17yo
Wow, very accurate, lol
I don't have many characters yet, but they are all teens/early teens, expect for the main character's mom, she is in her late 30's. Age is kinda important in my story.
I'm 23, I was 19 when I started developing my webcomic.
Hmm... Echo's 17, she'll turn 18 in the third book. Hrodland's 22, he'll turn 23 soon.
Characters ages go from 12 to +70. And because I was curious, I did some statitics one day. The average age is 30 years old, while if you don't count the old bags, the average age is 26 years old.
I'm not even 26.
All my characters are based on their real persona. However they slighty different in age. Silerna's 25 years old, while the real Silerna (me) is younger. All ages lie between 20 and 28 years old.
Hey, it's the truth. Some of them are old and cynic witches. 
Like that nice Oldbag from Ace Attorney : D 
I love stories about school, however old I get.... I like the experience and strong feelings that young people have even not in school. So my main characters are always teenagers or at least in their twenties. The good part is that as I get older, my understanding of the behaviour of the adults and the teenagers get better so the story becomes more deep and realistic. 
For Room for Improvement my characters have no age... I don't know when they were born. I don't think they do either.
As for my other comic, Gypsy Manor, the main character is 14 years old. And she's run over... Whelp
I'm 25 (started the comic when I was 22) and the main characters in my comic Creep1 are Riley (17), Alex (18), and Sam (16). The supporting cast ranges from 17 to Twenty-Something... and there are a few parents who are obviously older.
@getsuart Wendy Oldbag! <3 Oh gosh, she's one of my favourite characters! XD
I'm 18! The main cast for Kongene Faller (at least human wise) range from 15 - 65. However the two ''main'' characters who are 32 and 37 don't quite look their age :-p, though the 37 year old has an excuse for not looking his age. Only the 65 year old character looks his age but even then, I could always push it more in his design.
My next planned story, In Memoriam, the only human character is 23...then the rest of the cast are Angels so they're going to be ridiculously old (but not look it).
I'm 22 but I started developing Fallacy when I was about 20.
My main 4: Nidi - 21, Thjalfi - 20, Astrid 27, Hildr - 24.
Rest of the characters are 27 - 56, most near or in their thirties. Oh, I do have one character who is 13. There is also one undecided character who might end up being very old but I haven't really thought about her too much yet as I won't need her for years. :'D
Runewriters (fantasy (/action/comeddddyyyy???))
Protagonists: Tareth is 17 and Severian is 20. Jonan is 29 (though he looks much older) and Xira is 15. There's another character who'll be introduced soon that's 11.
Antagonists: Quentin Agorath is 23 (he'd look it if he got some sleep), Esra is 30, and Iavin is 44.
I'm gonna be 29 in December (HAPPY BDAY TO ME) but I was around 19-20 when I first started developing these guys!
I'm 23. As for my characters:
Kestrel is about 17, Jerzy is turning 20 in about a month, Karamanczi ~32, Young something about 40, Thomas ~25, Ellie~21, Rikka is about 14-15 and Max is 14.
I'm 25, and though these are not all the major characters in West there is definitely a trend.
Jed: 33
Serge: 38
Morris: 29
Jorik: 62
Glista: 29
Since leaving school I haven't spent any time around younger people at all. Went straight to work and never looked back. I have no idea what kids are like independent if my own memories and I'm pretty scared about introducing them. I've even googled kids of different ages because I'm not sure what they look like, how bad is that?
I totally understand! I'm making fewer younger characters nowadays because I feel a disconnect with them in real life.
I'm 21, will be 22 in a few weeks! I came up with Heroes of Thantopolis1 in my senior year of college, when I was 17.
The protagonist Cyrus is 12, and will be 13 at the end of the comic.
Helene is an immortal goddess, she's thousands of years old, age is an illusion.
Sagittarius is as old as the invention of the western zodiac
Trickster and Xisea are dead; Trickster acts like a radical teen, while Xisea is like a child.
When I was younger most of my stories were about young adults or adults. Now I'm an adult and most of my stories are about kids or teens.
It's understandable @ScampiCub, and it's totally okay. Children change so much!
Exactly! When 99% of your time is spent with older people it's going to impact you some how, and as you get older it becomes harder and harder to expose yourself to different groups.
Luckily a few months ago we had an event at work where a face painter was involved and there were kids everywhere. I spent the whole day asking kids how old they were. It's amazing how different two 8 year-olds can look.
@getsuart They really do. It's also insane how vastly different they are between families.
Well, well it is a hard question. So much depends of the script. But in general my main character are in 20-30 years old. But a lot of them are more than 60s. I don`t think age is universal for my stories, the plot will make the age of them. In some of my stories pass an entire character life.
My stories are very influenced by 1800s literature, because of that, have an entire variety of ages.
