For the very first time, in the Spring of 2023, the European Commission (EC) carried out a survey across all member states to assess their level of financial literacy. This survey complements other national surveys and fills an important gap because it provides a consistent metric that allows comparisons among the European Union (EU) countries. The motivation behind the EC’s survey stems from the need to advance the state of financial literacy to safeguard financial stability and promote important projects, such as the creation of a Capital Markets Union. In this paper, we analyze these new data and confirm findings in the literature about the importance of being financially knowledgeable to achieve good financial outcomes. Unfortunately, the survey also confirms that barely one in two individuals, on average in the EU, is financially literate.

This paper surveys what we have learned on financial literacy and its relation to financial behavior from data collected in the Dutch Central Bank (DNB) Household Survey, a project done in collaboration with academics. A pioneering survey fielded in 2005 included an extensive set of financial literacy questions and questions that can serve as instruments for financial literacy in regression analyses to assess the causal effect of financial literacy on behavior. We describe how this survey spurred a series of research papers demonstrating the crucial role of financial literacy in stock market participation, retirement planning, and wealth accumulation. This inspired various follow-up studies and experiments based on new data collections in the DNB Household Survey. Researchers worldwide have used these data for innovative studies, and other surveys have included similar questions. This case study exemplifies the essential role of data in empirical research, showing how innovative data collections can inspire new research initiatives and significantly contribute to our understanding of household financial decision-making.

We provide a brief history of administering financial literacy questions in probability-based Internet panels. After financial literacy questions were asked in the Centerpanel in the Netherlands and the RAND American Life Panel, the Understanding America Study (UAS) has been administering 14 financial literacy questions in its biannual core surveys since 2014. Due to its longitudinal nature and the vast amount of available information on its panel members, the UAS provides unique opportunities for analyzing patterns of financial literacy over time and its associations with financial outcomes, cognition, health, personality, and economic preferences, among others. The UAS survey-based dataset is further enriched with administrative records from consenting respondents. Importantly, researchers can incorporate additional questions and modules to gather specific data, which can then be linked to both existing and forthcoming information on panel members. In this paper, we describe the UAS financial literacy measures and offer descriptive analyses, highlighting the patterns of financial knowledge over time and by individuals’ background characteristics. We also show how financial outcomes, such as financial wealth and retirement preparedness, relate to financial literacy scores.
