Do rising gay identification rates among young adults match actual behavior?
Core argument: In the General Social Survey, 20% of American young adults report having had sex with a same-sex partner, slightly exceeding the 18.5% who identify as gay, lesbian, or bisexual.
Some reports have suggested that increases appear primarily in LGB identification, but not much in behavior. In other words, more young adults identify as LGB, but they are not necessarily acting on it. At least in the data from the General Social Survey, that does not appear to be true: There has also been a significant increase in young adults having homosexual sex (men with men and women with women). In fact, slightly more American young adults have had sex with a same-sex partner — 20% (see Figure 4) than identify as gay, lesbian, or bisexual — 18.5% (see Figure 2). The increases are even larger for 27- to 41-year-olds (the next older age group), perhaps because they have had more time to accumulate sexual partners since age 18.
