Gender spectrum

Gender spectrum or gender continuum is a term often used as a metaphor to help explain nonbinary identities.

In its most simplistic form, the gender spectrum is a line going from male on one end to female on the other end. However, this does not fully adequately include all genders; many nonbinary genders are not "between male and female".

The phrase "on the gender spectrum" is sometimes used as a synonym for "nonbinary" or "gender nonconforming".

Gender Spectrum is also the name of a USA-based gender inclusion organization.

History
The phrase "gender spectrum" dates back at least to the 1980s. For example, in a 1985 issue of the crossdressing/transsexualism magazine "Tapestry", a listing for a therapy group is described as including "transsexuals, transvestites and persons who are trying to find themselves on the gender spectrum."
