We're working on a project that encourages bicycling for people across the country—as both recreation and commute. As part of our demographic questions, we would like to know the gender of the participant.
So far, we have:
I identify as a… • female • male • I prefer not to say
What if someone doesn't identify as either, but they would prefer to say that? Is there a proper way to do this while keeping three possible selectors?
Thanks for your help.
