An umbrella and personal identity for genders not exclusively woman or man. Non-binary experiences can include having no gender, more than one gender, a fluid gender or another gender entirely.

In brief
Genders beyond exclusive woman-or-man categories, with wide internal diversity.
Non-binary people may use terms such as genderqueer, agender, bigender or genderfluid, or simply non-binary. Some identify as trans and some do not. Pronouns, expression, anatomy and transition choices vary and cannot be inferred from the label.
Many non-binary experiences
Some people feel between woman and man, both, neither or unrelated to that spectrum. Non-binary is not automatically a third fixed gender.
Identity can be stable or fluid. A person's exact label may change as language and self-understanding develop.

Read the rest: evidence, law, safety and sources
Non-binary
A broad umbrella or specific identity outside exclusive woman-or-man categories.
Agender
An identity involving no gender, genderlessness or a minimal relationship to gender.
Genderfluid
An experience of gender that changes over time or context.
Genderqueer
A reclaimed identity challenging or exceeding conventional gender categories; not everyone embraces the term.
Pronouns and expression
Many non-binary people use they/them, while others use she, he, neopronouns or combinations. Ask and practise rather than assuming.
Presentation can be feminine, masculine, androgynous or variable. Nobody has to look neutral or disclose anatomy to qualify.
Bodies and healthcare
Some non-binary people seek hormones or surgery and others do not. Care goals may differ from binary transition pathways and should be discussed individually.
Screening and reproductive care depend on anatomy, hormones and history. Inclusive systems should not force inaccurate binary answers when the data is unnecessary.
Recognition, privacy and law
Not all UK documents offer a non-binary marker, creating practical mismatches that do not invalidate identity. Previous names and gender history require confidentiality.
Legal protection under gender-reassignment provisions depends on statutory facts, and coverage of non-binary people can be context-specific. Obtain current legal advice for an individual dispute.
