Almost 900 transgender people in Ireland officially changed their gender in less than seven years.
According to new figures released to Newstalk, a slight majority were people transitioning to female.
Since September 2015, people can apply to the Department of Social Protection to get a Gender Recognition Certificate to have their new gender recognised by the state.
As of the end of 2021, a total of 882 certs had been issued.
'A two-page form'
Carolyn Ann Willis, who lives in Co Leitrim, got her gender changed to female in 2017.
She said the process was very straightforward.
"If you want to have your different name on your certificate, you have to have it legally changed before they issue your certificate," she said.
"You [have] got to send all that into them with your name-change and your passport and they change it.
"It's basically just, fill out a two-page form".
To get a cert at the moment, you need to fill out an application form, have it witnessed by a qualified person, and send it to the department along with your birth certificate and proof of residency.
You need to be at least 18, but 16 and 17-year-olds can get them in limited circumstances.
