The OECD averages include only OECD countries. Similarly, EU averages include only EU member states and are calculated as unweighted averages. OECD and EU averages are calculated for member countries with available data, and the number of countries which are part of the averages can differ. OECD and EU averages are calculated based on the OECD and EU member countries presented in the respective figure or table, with all data accessible via the OECD’s StatLinks service.
In Chapter 6, “Empowering through health literacy: Skills to navigate health information and make informed decisions”, data from the European Health Literacy Population Survey 2019-2021 (HLS19) are used where 15 OECD countries participated and refer to the OECD average in this chapter as “HLS19 OECD average”.
