Data on sex is vital across a range of domains, including health, criminal justice, education and employment. In recent years, confusion over the concepts of sex, gender and gender identity has led to a loss of robust data on sex
🚨Announcement!🚨
The government-commissioned Sullivan Review of Data and Statistics on Sex and Gender has been published by the Department of Science Innovation and Technology @SciTechgovuk (link in reply)
@ucl@IOE_London@UCLSocRes
The review provides concludes that organisations need data on biological sex and that there is no legal barrier to collecting this. Data on gender-diverse identities should be collected as a distinct variable, rather than muddled with sex
We've been blown away by the level of media coverage for the Sullivan Review. It's not every day that a social statistics project makes editorials in the Times, Observer and even... the Sun.
Prof Sullivan concluded that biological sex and gender identity must be distinguished from each other, and that the word “gender” should be avoided altogether because it has multiple distinct meanings.

Review lead @profalices says “I hope that the report’s recommendations will be taken up by all organisations that have in recent years drifted away from collecting data on biological sex, and will give confidence that they can do so lawfully.”
The Review of data, statistics and research on sex and gender welcomes submissions to our call for evidence.
We invite submissions of evidence on:
Examples of flawed data collection on sex and/or gender identity
Barriers to research
The terms of reference for the "Review of data, statistics and research on sex and gender" have been published.
We will be launching a call for evidence in due course.
Please follow this account for updates.
The Sullivan Review underlines the importance of recording biological sex - not just for research and insight, but also patient safety.
Doing so does not prevent us from recording, recognising and respecting people’s gender identity where these differ.
We’ll act on findings.
Following the Supreme Court judgment on the meaning of "sex" in the 2010 Equality Act, we have published an addendum to our report on data and statistics on sex and gender.
This explains how the judgment dovetails with the recommendations of the review.
Have you faced any barriers to research on sex and gender?
If so, please submit your experience to the call for evidence.
We are looking for "ordinary" stories, not just dramatic ones.

The Observer @ObserverUK editorial:
"A report lays bare the extent of real-world detriment caused by institutions that have caved in to activist pressures"
