This is a given.

If the last digit is divisible by 2 (a.k.a. even), then so is the whole number.

If the sum of the digits is divisible by 3, then so is the whole number. The recursivity of this means that if the sum has multiple digits, you can add them up again until you get a single digit and see if it's 3, 6, or 9.

Like the rule for 2, but check if the last two digits are divisible by 4.

If it ends in 5 or 0.

If the rules for both 2 and 3 apply.

No shortcut. Alas.

Like the rules for 2 and 4, but check if the last three digits are divisible by 8. (Yes, this pattern keeps going for 16, 32, etc.)

Like the rule for 3, but the sum of the digits (or the sum of the sum of the digits, etc.) must be 9.

The 13th annual international gender census, collecting information about the language we use to refer to ourselves and each other, is now open until 13th August 2026.

It’s short and easy, for most participants it takes 5 minutes or less.

After the survey is closed I’ll process the results and publish a spreadsheet of the data and a report summarising the main findings. Then anyone can use them for academic or business purposes, self-advocacy, tracking the popularity of language over time, and just feeling like we’re part of a huge and diverse community.

If you think you might have friends and followers who’d be interested, please do reblog this blog post, and share the survey URL by email or at AFK social groups or on other social networks. Every share is extremely helpful!

Survey URL: https://survey.gendercensus.com

The survey is open to anyone anywhere who speaks English and feels that the gender binary doesn’t fully describe their experience of themselves and their gender(s) or lack thereof.

Thank you so much!
