One 2000 study, based on an Internet questionnaire addressed to visitors of swinger-related sites, found swingers are happier in their relationships than the norm.
This study, which only polled self-identified swingers, is of limited use to a broader application to the rest of society (external validity) owing to self-selected sampling.

Different clubs offer varied facilities and atmospheres, and often hold "theme" nights.
In a 1992 study, an overall 7% of swingers had quit swinging because of the HIV/AIDS epidemic.
It was also stated that 62% of swingers changed their sex practices, by becoming more selective with partners or by practicing safe sex.
