Note: Descriptive statistics (unweighted) for responses in the Telegram survey (N = 8,798). Education level was reported differently, and is not included, for wave 4. Further details are available in Supplementary Information S4.2. Notice that in the “Gender” question, responses with “prefer not to say” were automatically excluded because of the impossibility of correctly imputing post-stratification weights.
