I didn't know about this! It's definitely interesting as a survey of queer folks, but given how few respondents were cis, definitely seems like the census is reaching a specific crowd.
The author says as much:
This all leads us to my never-ending problem: selection bias. The survey is 100% online, and spread entirely by word of mouth and social media shares.
So it certainly doesn't mean that the survey doesn't have value, but it would be interesting to see this survey with with a more generalized reach. But maybe my interest is rooted in my bias as a cis person. As is, still really cool to get some actual data on the overall trends for pronouns and self-labels and all that!
It is specifically targeted at folks who are not purely a binary gender (arguably by definition not cis, but I'm not going to enforce labels on anyone). Their preface/definition can be found below:
Who can take part?
The gender binary is a societal model that classifies all humans into one of two categories:
Woman/girl – always, solely and completely
Man/boy – always, solely and completely
If you feel like that doesn’t fit your experience of yourself and your own gender in some way, you are invited to participate. This includes, but is definitely not limited to:
people whose genders change over time
people whose genders fluctuate in intensity
people who experience more than one gender at a time
people who don’t experience gender at all
people whose gender is neither male/man nor female/woman
We also welcome anyone who:
rejects gender altogether
feels like they’re outside of gender
feels like they transcend or move beyond gender or the gender binary
doesn’t really understand gender as it applies to them
is questioning whether their flavour of trans might be binary or nonbinary
It’s completely up to you whether you feel you fit any of these. This survey leans on the side of inclusive.
