Well, there's people self-identifying, and there's people living the lifestyle, and the groups don't necessarily have to match up, like in the closet I guess.

Well, there's people self-identifying, and there's people living the lifestyle, and the groups don't necessarily have to match up, like in the closet I guess. With respect to living the lifestyle, Time has an interesting article on the percentage of college grads living at home after graduation, aka failure to launch. We'll assume 50:50 male:female although of course not all degree fields are 50:50, and we'll assume that living in moms basement means the sex life is essentially zilch. http://time.com/4106297/college-degrees-parents-house/ http://time.com/4106297/college-degrees-parents-house/ So half of English lit grads, 40% of CS/IT grads, 30% of engineers, more than half of history majors. You could argue that the extrapolated trend around 30 is more relevant than just out of school and trying to find a new career, in which case its merely in the 10% to 20% range depending on major. Far too many college grads are produced than there are jobs for them, by integer multiples too many. Its the opposite for skilled trades, you'll make a lot more money and demand is intense for electricians so I'd imagine "failure to launch" for journeyman electricians is exclusively limited to, like, in home hospice care of ill parents and similar, so figure that rounds down to about zero although I don't have figures. Maybe unemployed college grads living at home make it work, I never had to do it, but I imagine it would be awkward having uni roommate conversations with your parents and little sister to get them out of the house when you're having someone come over, or I guess they could stay home and listen, or just ewww. Personally I came home from the Army while going to school in the day and I couldn't take the parenting for more than a couple weeks while I was doing the school GI bill thing, of course that's all the time I needed to get an apartment and car and start school and stuff. Where are you going who you gonna hang out with how late will you be out remember tonight is a school night do I know their parents oh can I meet this girl she sounds nice, is kinda cute or tolerable around thirteen but not a 20-something adult. My score while living at home was definitely zero, although I was too busy setting up apartment, car, school, all that stuff to go out anyway. So in summary, mid level double digit percentages. Not a rounding error.
