The demoscopic survey, carried out by the University of Udine and the Ixè Institute of Trieste, involved a sample of 600 respondents, representative of the Italian population aged over 18 (50,243,518 as of 1/1/2019). The sampling followed a proportional design, with a priori definition of sample quotas, aligned with the most recent ISTAT data, with respect to the following parameters: gender, age class, geographical area, and size class of the municipality of residence. Considering the correlation with the phenomena investigated, based on official data, an a posteriori weighting was also carried out to guarantee correct distribution with respect to school level and voting behaviour at the last political elections. The sample size used ensured a fair degree of precision of the estimates, with a maximum margin of error of +/-4.01%. The interviews were carried out based on a structured questionnaire. Prior to the administration of the interviews to the sample, a pre-test was carried out between 01/10/2020 and 02/10/2020, by means of around 20 pilot interviews, which allowed for the validation of the questionnaire design and the wording of the various questions. Between 6/10/2020 and 10/10/2020, a total of 600 complete interviews were carried out, distributed as follows according to the survey technique: 100 telephone interviews (CATI system - Computer Assisted Telephone Interviewing) and 500 online interviews (CAWI system - Computer Assisted Web Interviewing). This distribution of interview techniques made it possible to over-sample the segment of Internet users during the survey phase, consistent with the topics addressed. The a posteriori weighting procedure in any case ensured sampling representativeness with respect to the overall distribution of the Italian adult population. Concerning the telephone interviews, public telephone directories and a panel of mobile phone numbers, provided with prior consent, in the availability of a partner of the Ixè Institute, were used. For the telephone interviews, a strategy based on a maximum of 6 contacts was followed, obtaining, after the survey, a response rate of 2.67%, in conformity with Response Rate 2, as defined by the American Association for Public Opinion Research. Regarding the online interviews, a panel of e-mails, provided with prior consent, was drawn from a partner of the Ixè Institute. A total of 1,447 invitations were sent out, obtaining 500 complete compilations from the target subjects according to the sample stratification established a priori, with a response rate of 34.55%.<br>
