Dear all, There is now an annual affiliate survey. Here are the questions https://meta.wikimedia.org/wiki/Global_Data_and_Insights_Team/Our_Reports/2021_Affiliates_data_survey/Memb_data_questionsit asks.
If you're up for being surved but not surveilled, you can take the survey anonymously https://wikimedia.qualtrics.com/jfe/form/SV_e5s72QFWkLzUm8t. It takes around ~20 minutes.
Warmly, SJ
