Tabulations by Gebhard (McWhirter 1990) on Kinsey's basic sample of noninstitutionalized males and females indicated that "13.95% of males and 4.25% of females, or a combined average of 9.13%" had had either "extensive" or "more than incidental" homosexual experience. 3.7% of females had extensive homosexual experience.
They found 9.9% of the males in the College Sample had extensive homosexual experience. In The Kinsey Data, Gebhard and Johnson (1979) reexamined the amount of homosexual experience in Kinsey's basic sample of noninstitutionalized males and females. His refined figures showed that between one-quarter and one-third of adult white males with college education had had an "overt homosexual experience since puberty" (mostly in the adolescent years) weighting by marital status, he estimated that 4% of the white college-educated males and between 1-2% (and closer to 1%) of white females were predominantly or exclusively homosexual. In the Final Report and Background Papers of the National Institute of Mental Health's Task Force on Homosexuality (Gebhard 1972), Gebhard reanalyzed Kinsey's data to eliminate sample bias.
