My current survey, open to everyone of any gender, in any location: https://docs.google.com/forms/d/e/1FAIpQLSdb0-hKaa5UReHFbAIx9fywyI3uDBDfW5sQMwd2eOtK3AhqfA/viewform
So far, 1,343 responses, 58% (776) of which haven't heard of the Gender Census (good!). I'm aiming for 1,000 people who haven't heard of the Gender Census, so any shares are very much appreciated, especially if it boosts the survey out of my usual extremely nonbinary circle.
Also, you can spy on some incoming public stats here without causing survey problems: https://docs.google.com/spreadsheets/d/1owsmN_dSGNV2T0DSAsHzKIqRd09AIiDEr0Ik0sOYdks/edit
