This webinar concretely delved into two types of perception measures – trust and subjective well-being (SWB)- to look at solutions for potential measurement challenges, and how such measures can inform political decision-making. Trust in other people and in public institutions as well as SWB have widely been recognised as key ingredients of people’s well-being and are essential for societies to flourish, but official data remains scarce. Under its Better Life Initiative, the OECD has published official guidelines on measuring trust and SWB to assist data producers in collecting and reporting these measures, and to support data users in understanding different measurement approaches and their implications for analysis. This webinar: (1) provided evidence from the OECD Guidelines on the statistical quality and best approaches for measuring trust and SWB in a reliable and consistent way, (2) reflected on these issues in a Latin American context, and (3) gave practical examples of how trust and SWB surveys have been used by the POLIS institute in Colombia to evaluate policy interventions and provide rapid results on the impact of COVID-19 on happiness.
