Non-Binary

Definition
Non-binary is a spectrum or umbrella term for gender identities that aren't exclusively male or female. Anyone that is not always and solely 100% male or female can be considered non-binary, however it is important to note that not everyone who falls outside the gender binary has to classify their identity as non-binary. And while the term "non-binary" is commonly used as an umbrella term, one does not have to specify their gender past being non-binary and it can be used as a gender on its own.

The Gender Binary
The gender binary is a term often used within the non-binary community that refers to the fact that most of society seems to only see two genders - male and female. Male and female are binary genders, hence the fact that any genders that aren't exclusively male or female can be considered non-binary.

Flag
The non-binary flag has four stripes: yellow, white, purple, and black. The yellow represents people whose gender exists outside of the binary, white symbolizes those who embrace many or all genders, purple represents those whose gender is a mixture of - or in between - the binary genders, and black represents lack of gender.

Terminology
Riki Anne Wilchins claims to have coined the term non-binary and used it in a published essay in 1995. The current non-binary pride flag was designed by Kye Rowan in 2014.
