We're in the process of adding more gender measures based on consultations with agencies serving immigrants and refugees. So far, they have requested that we add the Fenway and HRC definitions to our options:

Human Rights Campaign (HRC)
1 Male
2 Female
3 Non-binary/ third gender
4 Prefer to self-describe [open text]
