We analyzed 104 respondents who clicked on a survey link from within the interface of
Ninety percent of my respondents were between ages 18-30, and 71% came from the US, 14% from Australia, and 15% from other countries.
So bottom line: if a roommate's significant other stays about half the time or less and has their own place, they shouldn't be expected to systematically contribute to bills or rent (but might want to bring a few host gifts out of politeness).
