Heterosexual-Homosexual Rating Scale (Kinsey scale)

The Kinsey scale, also called the Heterosexual-Homosexual Rating Scale, attempts to describe a person's sexual history or episodes of his or her sexual activity at a given time. It uses a scale from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. In both the Male and Female volumes of the Kinsey Reports, an additional grade, listed as "X", was used for asexuality.

Kinsey reports
  • Men: 11.6% of white males aged 20–35 were given a rating of 3 for this period of their lives. The study also reported that 10% of American males surveyed were "more or less exclusively homosexual for at least three years between the ages of 16 and 55" (in the 5 to 6 range).
  • Women: 7% of single females aged 20–35 and 4% of previously married females aged 20–35 were given a rating of 3 for this period of their lives. 2 to 6% of females, aged 20–35, were given a rating of 5 and 1 to 3% of unmarried females aged 20–35 were rated as 6.

"Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheep and goats. It is a fundamental of taxonomy that nature rarely deals with discrete categories... The living world is a continuum in each and every one of its aspects." (p 639).

"While emphasizing the continuity of the gradations between exclusively heterosexual and exclusively homosexual histories, it has seemed desirable to develop some sort of classification which could be based on the relative amounts of heterosexual and homosexual experience or response in each history... An individual may be assigned a position on this scale, for each period in his life.... A seven-point scale comes nearer to showing the many gradations that actually exist." (pp. 639, 656)
