Police Scotland: Review of Sex and Gender Data Recording

This is our submission to the Police Scotland consultation on its review of sex and gender data recording. The consultation closed on 22 June 2025.
Police Scotland proposes to adopt the following definitions of sex, gender identity and gender reassignment:
- Gender reassignment: the process of changing one’s sex to align with a person’s gender identity. A person has the protected characteristic of gender reassignment under the Equality Act 2010 if the person is proposing to undergo, is undergoing or has undergone a process (or part of a process) for the purpose of reassigning the person’s sex by changing physiological or other attributes of sex.
- Sex: the biological sex of a person assigned at birth based on physiological characteristics including chromosome composition and reproductive organs.
- Gender identity: a person’s internal sense of how they perceive themselves in terms of gender. Gender identity can be the same or different from the sex of a person assigned at birth.
Questions to be asked by Police Scotland when sex and gender identity are specifically required to inform police action e.g. searches in custody (strip searches; intimate searches):
Question 1
Option A: What is your sex as assigned at birth?
Option B: What is your birth sex?
Option C: What is your sex registered at birth?
[Male, Female, Not disclosed]
Question 2
Do you consider yourself to be:
transgender;
non-binary; or
gender diverse?
[Yes – trans man, Yes – trans woman, Yes – Non-binary, Yes – Other, No, Not disclosed]
(If the answer to this is no, then no need to move to question 3)
Question 3
Do you consider yourself to have the protected characteristic of gender reassignment?
[Yes, No, Not disclosed]
Question 1
To what extent do you agree or disagree with the proposed approach for recording sex and gender for Police Scotland?
Strongly agree / Agree / Neither agree nor disagree / Disagree / Strongly disagree / Don’t know
Which option is your preference for ‘Question 1’ in the section above?
Option A: What is your sex as assigned at birth? / Option B: What is your birth sex? / Option C: What is your sex registered at birth?
Comments:
The given definition of sex is incorrect as sex is not “assigned at birth”. We would suggest an alternative definition of: “Sex means being male or female. It is an objective, biological characteristic about a person that is observed at birth.”
For consistency across organisations the form of the question should follow the UK Censuses (England and Wales, Northern Ireland, Scotland) question: “What is your sex?”, with the response categories “Female, Male”.
If needed, and to clarify a Gender Recognition Certificate is not taken into account, guidance for the sex question should provide clarity on the target of the question as follows. “This question is about your sex at birth”.
Since this question relates to intimate searches, an accurate response is necessary for the safeguarding and dignity of the respondent and police officers. It is therefore not appropriate to offer an option to not disclose the information and further investigation should be undertaken to establish the facts if needed.
Question 2
Do you support the proposed response options in ‘Question 2’ within the ‘More information’ section above?
These are proposed as follows:
[Yes – trans man, Yes – trans woman, Yes – Non-binary, Yes – Other, No, Not disclosed]
Yes/ No / Don’t Know
Comments:
Care should be taken only to collect information which is needed. For the purposes of conducting intimate searches the relevant information is sex, so a transgender question should not be asked in this context.
We strongly recommend that the option of “gender diverse” is not included in any question as this can easily be seen to include people who do not conform with gender stereotypes but do not consider themselves to be transgender.
The Hate Crime and Public Order (Scotland) Act 2021 is the only legislation that references “transgender identity”. In order to categorise crimes for this purpose the form of the question should follow its terms (allowing for a “No”, and “Prefer not to say” response) as follows:
Do you consider yourself to be:
- a female-to-male transgender person;
- a male-to-female transgender person;
- a non-binary person; or
- a person who cross-dresses.
“Transgender identity” in the Hate Crime Act is different from the term “gender identity” and applying a concept from a small group who consider themselves transgender to the broader population is problematic. “Gender identity” is a disputed and controversial concept, and there is no agreed definition. Indeed the definition given in the accompanying notes to this consultation allows for a gender identity to be the same as sex at birth. But gender identity is not sex, they are different and distinct concepts with different definitions, so this cannot be correct. Any such conflation is confusing and unhelpful.
“Gender identity” is also not a protected characteristic and there is no requirement under the PSED for such data to be collected.
Consideration should be given instead to asking about the protected characteristic of gender reassignment which may be necessary for the purposes of equalities monitoring. A question on transgender identity is unlikely to be a good substitute or specific enough as some identities (non-binary, agender, etc) are not covered by the gender reassignment characteristic and will not assist in compliance with the PSED.
The definition of gender reassignment given in the information accompanying this consultation erroneously includes the phrase “the process of changing one’s sex to align with a person’s gender identity”. However, the definition of gender reassignment in the Equality Act does not refer to the concept of “gender identity” and we recommend the Act’s definition should be adhered to without any additions.
To capture the protected characteristic of gender reassignment, we suggest asking a direct question addressed to this target, such as: “Do you have the protected characteristic of gender reassignment?” with response options: Yes/No/Don’t know/Prefer not to say.
A guidance note should be included prominently alongside the above question as follows: “A person has the protected characteristic of gender reassignment if the person is proposing to undergo, is undergoing or has undergone a process (or part of a process) for the purpose of reassigning the person’s sex by changing physiological or other attributes of sex.”
Despite the cumbersome language of the legislation, testing by the Equality and Human Rights Commission suggests that respondents are willing to answer a question framed in these terms.
However, data should only be collected which is needed for a specific purpose. The PSED does not imply a duty to ask for data which is unlikely to be useful and it may be that the collection of sensitive data which identifies a small group of people is not necessary.
Question 3
Should we include a ‘not disclosed’ option when asking for sex and gender data?
Yes / No / Don’t know
Comments:
NB. This is a different Question 3 from that given in the notes accompanying the consultation. We have answered that question about gender reassignment in Question 2 above.
Where sex data is collected for the purposes of intimate searches a “not disclosed” option should not be provided since an accurate answer is necessary for the safeguarding, welfare and dignity of the respondent and police officers. Further investigation should be undertaken to establish the facts if needed.
Collection of data on sex is required to fulfil the PSED and, in order to give an accurate picture as possible, an opt out should not be given. Accuracy in crime statistics is similarly important and any proportion of respondents not disclosing their sex could quickly lead to a significant distortion in data, particularly when crime numbers for a particular offence are small or crimes are sex specific. Where information on sex is not essential it is fine to provide an option not to disclose but organisations should not be asking the question where the information is not required. Sex data is not sensitive data and if it is needed, it should be provided accurately with no opt out.
Data on “gender” should not be collected at all. This is a confusing term and is likely to lead to corrupted data that is a mix of sex and “gender identity”. Where questions are asked about the specific concept of gender identity the respondent should have the option of “None” as well as “prefer not to say”. Similarly, with a gender reassignment question the option not to disclose should be available since this may be considered sensitive data and relates to a small population.
