According to 2010 estimates by the Kinsey Institute "swinging is relatively uncommon in the United States".

John Stossel produced an investigative news report into the swinging lifestyle.

Stossel's report in 2005 cited Terry Gould's research, which concluded that "couples swing in order to not cheat on their partners".

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.

The phenomenon of swinging, or at least its wider discussion and practice, is regarded by some as arising from the freer attitudes to sexual activity after the sexual revolution of the 1960s, the invention and availability of the contraceptive pill, and the emergence of treatments for many of the sexually transmitted diseases that were known at that time.

The adoption of safe sex practices became more common in the late 1980s.

Swinging, sometimes called wife swapping or partner swapping, is a non-monogamous behavior in which both singles and partners in a committed relationship engage in sexual activities with others as a recreational or social activity. People may choose a swinging lifestyle for a variety of reasons.

Many cite an increased quality, quantity, and frequency of sex.

The swinger community sometimes refers to itself as "the lifestyle", or as "the alternative lifestyle".
