I don't know if there is a "type". But I would have to say, from my observations, most of the moms are not like me at all. The majority of them are SAHM, with less than a college education who are conservative politically and socially. I also noticed there is an above average number of homeschoolers and fundamentalist Christians. I'm none of those things.
As far as age and region go, the majority I see are in their early to mid 20s and from the south.
