New York has added an “X” gender-neutral option on various state issued ID cards. Those include birth certificates, permits, drivers licenses, etc. It's made for those who wish to not specify their gender.
NY Gov Andrew Cuomo signed the bill yesterday. It was the 10 year anniversary of New York's Marriage Equality Act coming into law in 2011.
Cuomo was quoted in saying:
“Every New Yorker deserves to be free from discrimination and have state-issued identification and processes that respect them for who they are, recognize their gender identity and protect their safety... New York continues to lead the way in ensuring LGBTQ people are treated equally in every part of the law and society, and this bill is another landmark that ensures New Yorkers can express ourselves for who we are.”
