Ages since I’ve been to the local club, but it’s a middle-aged, middle-class, male bunch. I get the impression the average age of wargamers has increased in the last few decades, with video games (and to a lesser extent RPGs) seeing a much younger crowd, with – shock – a few women present. When I started going to a wargames club in the early 90s I was in my mid-teens and I wasn’t the youngest there, and the average age was probably 30. Now I think it’s closer to 50, with quite a few people in their 40s who haven’t gamed for years returning to play with their childhood toys (I never really stopped). Even the local GW seems to draw an older clientele.
I’m starting to feel a bit sad. Like this: 
Bald, round, and sallow; your typical wargamer.
