I'd like to say you are wrong, but it's possible we are in different west coast cities. Meetups where I am (SF area) are pretty well populated with single women looking a mate or at least new friends. You may have to go outside your comfort zone to attend meetups that women are more likely to go to.
My personal experiences with this: you'll find a good gender balance in groups for going trail hiking, especially with their dogs because everyone loves dogs and sometimes people have dogs because they are single. :) Wine tasting groups generally have more women. Movie watching groups have slightly more women. JQuery meetups have nearly no women. :)
