New York City Mayor Bill de Blasio signed a bill into law on Tuesday, which will add a third gender category on birth certificates issued in the city.

“New Yorkers should be free to tell their government who they are, not the other way around,” de Blasio said. “This new legislation will empower all New Yorkers — especially our transgender and gender non-binary residents — to have birth certificates that better reflect their identity, and it furthers the City’s commitment to defending the rights of our LGBTQ community.”
