Pondering age demographics

Of course the Internet is host to all kinds of spaces and social medias, and different demographics are drawn to different sites. Communities will organically form and often primarily features similar demographics. Maybe there's a confirmation bias happening here, but I feel like this site is dominated by much younger people (<18 year olds). 

I'm mid-20s (oof, only 1 more year that I'm closer to 20 than 30...) which in the grand scheme of things is actually quite young, but on this site it's making me feel old! It's really fun to see younger people form their own communities here, I just would love to be in more contact with people who know what paying rent is like ;-)
