Financial literacy has gained an important position in the policy agenda of many countries, and the importance of collecting informative, reliable data on the levels of financial literacy across adult populations has been widely recognized (OECD/INFE 2015a). At their summit in Los Cabos in 2012, G20 leaders endorsed the High-Level Principles on National Strategies for Financial Education developed by the Organisation for Economic Co-operation and Development International Network on Financial Education (OECD/INFE), thereby acknowledging the importance of coordinated policy approaches to financial education (G20 2012).
