Important notice

The Office for Statistics Regulation confirmed on 12/09/2024 that the gender identity estimates from Census 2021 are no longer accredited official statistics and are classified as official statistics in development.

For further information please see: Sexual orientation and gender identity quality information for Census 2021

These datasets provide Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales for gender identity by sex, gender identity by age and gender identity by sex and age.

Gender identity

Gender identity refers to a person's sense of their own gender, whether male, female or another category such as non-binary. This may or may not be the same as their sex registered at birth.

Non-binary

Someone who is non-binary does not identify with the binary categories of man and woman. In these results the category includes people who identified with the specific term "non-binary" or variants thereon. However, those who used other terms to describe an identity that was neither specifically man nor woman have been classed in "All other gender identities".

Sex

This is the sex recorded by the person completing the census. The options were "Female" and "Male".

Trans

An umbrella term used to refer to people whose gender identity is different from their sex registered at birth. This includes people who identify as a trans man, trans woman, non-binary or with another minority gender identity.

Trans man

A trans man is someone who was registered female at birth, but now identifies as a man.

Trans woman

A trans woman is someone who was registered male at birth, but now identifies as a woman.

Usual resident

A usual resident is anyone who on Census Day, 21 March 2021, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

Notes:

• To ensure that individuals cannot be identified in the data, population counts have been rounded to the nearest five and counts under 10 have been suppressed.

• Percentages have been calculated using rounded data.

Human sexuality is a complex reality, characterised by gender identity and sexual orientation. A widespread approach to study human sexuality is to compare groups with opposite sexual gender identity and sexual orientation such as cisgenders vs transgenders and heterosexuals vs homosexuals. Cisgenderism refers to individuals whose sense of gender identity corresponds to their natal sex, while transgenderism is characterized by an incongruity between biological sex and psychological gender with cross-gender identification. Heterosexuality refers to those who feel an emotional, romantic or sexual attraction towards the opposite sex, while homosexuality is characterized by an emotional, romantic or sexual attraction towards same sex individuals. Neuroimaging studies have found brain differences between these groups of individuals. Nevertheless, their results are conflicting, and limitations such as small samples' sizes and the considerable overlap between such groups, makes it difficult to draw accurate conclusions. This systematic review and meta-analysis explored structural, functional and metabolic features of the 'cisgender brain' compared with the 'transgender brain' before hormonal treatment and the 'heterosexual brain' compared to the 'homosexual brain' from the analysis of the neuroimaging literature. Processing the information that conform this dataset suggests that neuroanatomy, neurophysiology and neurometabolism in transgenders resemble those of their natal sex rather than those of their experienced gender and in homosexuals these resemble those of their same sex heterosexual population rather than their opposite sex heterosexual population. However, the small number of studies that contributed data, their small sample size, the incompleteness of the data, and the heterogeneity of the investigations that were included in this systematic review do not allow drawing general conclusions. This dataset contains all data extracted from the publications included, as well as the search strategy and the results of processing the information extracted from the articles
