The ONS had been a member of Stonewall’s flagship diversity champion programme since at least 2006, but its severing of ties has now come to light.
A spokesman for the ONS said that “lessons learned from 2021 will be incorporated” in the planning for the next census in 2031.
Documents released under freedom of information laws show that the ONS consulted closely with Stonewall ahead of the 2021 census on the question: “Is the gender you identify with the same as your sex registered at birth?”. It was the first time the census had surveyed gender identity.
The census’s transgender data was later stripped of its accredited status in 2024 as the question had been widely misunderstood, leading to dubious spikes in the data.
Prior to the break, the ONS collaborated closely with Stonewall and other LGBTQ charities and lobby groups. It met with representatives from Stonewall 31 times, Gendered Intelligence four times, and Gender Identity Research and Education Society (GIRES) four times between 2018 and 2025, according to a freedom of information request.
Other information requests showed that in a 2018 meeting between the ONS and transgender lobby groups, including Stonewall and GIRES, some attendees argued the census’s gender identity question “could be asked of those aged two and above”.
GIRES urged the ONS to ditch the minimum age completely “because gender identity is not age dependent and therefore age is irrelevant”.
Officials from the department for education, who were also present at the meeting, are noted in the minutes as saying there was “clear justification for asking the question to those under 16”.
