I had also noticed the large proportion of SEN DC and the fact that many of them could be described as geeks 
At DDs school it's kind of cool to be a geek though
They all watch Star Trek (including the really old William Shatner ones where they all seem to love Mr Spok), Sherlock Homes (incl black & white Basil Rathbone ones), watch Anime, read Marvel and DC comics and watch the films, and listen to 80s music (aaarggghhh)
They make Physics jokes (!) and the majority (unsurprisingly) don't have boyfriends. Spending time on makeup, hairstyles and clothes is positively frowned on.
.....it's kind of an anti fashion thing but 'the gang' is about 30% of the year and really inclusive.
They do have a fair number of 'parties' which seem dull by comparison to my youth
Many of your DC would 100% fit in and be welcomed with open arms. So there are lots of geek girls in my area that would be perfect for many of your geek boys
