One in eight people in Ceredigion aged under 35 years old identify with an LGBTQA+ sexual orientation, new census figures show.
Stonewall said the latest census breakdown shows that with each passing generation, more people feel safer to come out as LGBTQA+ and live as their true selves.
The census data shows 1,660 people aged between 16 and 24 years old in Ceredigion said they identified with a sexuality other than heterosexual when the census took place in March 2021, alongside 500 aged 25 to 34.
It means about 12.3 per cent of those aged under 35 in Ceredigion said they identified with an LGBTQA+ sexuality.
Across England and Wales, the majority of LGBTQA+ people were aged between 16 and 34 years (57.9 per cent), with about 6.2 per cent of the age group identifying with a minority sexuality.
The category LGBTQA+ covers people identifying as lesbian, gay or bisexual, as well as pansexual, asexual, queer or any other sexual orientation apart from heterosexual.
The proportion of LGBTQA+ young people varied across the nation with Brighton and Hove at the top of the list (14.8 per cent of under-35s) and Slough at the bottom (2.8 per cent).
Additionally, the data shows females in Ceredigion were more likely to identify with a minority sexuality – with 1,860 saying they were not straight compared to 1,135 males.
Nationally, 830,000 females (3.3 per cent) identified with an LGBTQA+ sexual orientation compared to 706,000 males (3 per cent).
The census also asked people, for the first time, about their gender identity. In Ceredigion, 380 (0.6 per cent) people said they did not identify with the gender assigned to them at birth.
The figures show 255 people aged 16 to 24 years said they were transgender – accounting for 67.1 per cent of the trans community in the area.
In England and Wales, people aged 16 to 24 years old were the most likely age group to have said their gender identity was different from their sex registered at birth.
About 1 per cent of the younger age cohort said they were trans, followed by 0.8 per cent of people aged between 24 and 34 and 0.6 per cent of people aged 35 to 44 years old.
Stonewall said: "Following the initial data showing over 1.5 million lesbian, gay and bi people living in England and Wales, we now see that younger generations feel safer to be themselves.
"Each generation reports more lesbian, gay and bi people than the last – but that doesn’t necessarily mean there are now simply more of us. It suggests that older generations were not always safe or free to speak about their experiences, or lacked the language to describe them."
The charity added the data is a reminder to leaders, institutions and governments to champion the LGBTQA+ community.
