Gender non-conforming, often shortened to GNC, is a term used to describe individuals who do not conform to societal gender roles. It is not the same as non-binary, which is a gender identity. GNC includes both cisgender and transgender people.
A gender role is behavior or characteristic traditionally ascribed to a person based on their biological or perceived sex. The term was coined by sexologist John Money, during studies of intersex children to describe "... all those things that a person says or does to disclose himself or herself as having the status of boy or man, girl or woman, respectively." These roles vary, often depending on one's age, location, race and ethnicity, and religious or other beliefs.
Most people do not fully ascribe to one or the other gender role — for example, many men enjoy cooking and baking, and many women play sports and video games — and doing so does not make one transgender or non-heterosexual. Studies have shown that gender non-conforming and gender dysphoric children are more likely to identify as cisgender and homosexual than transgender when they grow up.
