An ABBL Foundation/CSSF survey conducted by ILRES in December 2022 among more than 1,000 Luxembourg residents aged 18 to 79 years, the results of which were compared with those of the OECD survey conducted in 2020 in 26 other countries, in the same format. The findings are alarming: Luxembourg residents under 30 have a very low level of knowledge about personal finance, combined with behaviours and attitudes that are well below the European average. More than ever, we need to redouble our efforts in financial education.
