A more sustainable society and economy also implies more sustainable behavior in terms of the consumption of financial products. A possible change in this behavior can be brought about when there is a change in the demand. In other words, more sustainable consumption of financial products is directly related to financial literacy. However, the latter’s definition, object, and scope are far from being agreed upon internationally. One objective of this work was to explore the different interpretations of financial literacy in academic literature. In this exploration we delved into the evolution of the term, and how, in what context, and with what other concepts the term is used in social networks. Scientometric techniques were used for the analysis and review of the literature. The NLP technique was used to analyze comments on social networks. With this technique, ten feelings that were specially selected were analyzed. Positivity, confidence, and anticipation predominated among them. We conclude that it is important to emphasize that greater attention must be given to financial literacy, from both private and public sectors, so that it can be used to drive more sustainable behavior by individual consumers. Finally, a new definition of financial literacy is proposed.

A more sustainable society and economy also implies a more sustainable behavior in the consumption of financial products. A possible change in focus can come from the demand side, so that more sustainable consumption of financial products have to go hand to hand with financial literacy. However, financial literacy, potential favoring of this sustainable behavior, is far from reaching an international consensus about its definition, object and scope. Two objectives are analyzed; the different interpretations of financial literacy in the academic literature, as well as its evolution and how, in what context and with what other concepts the term is used in social networks. Scientometric techniques and content analysis have been used to carry out a systematic review of literature and also NLP to analyze the comments on Social Networks. Critical moments are identified in the definition of financial literacy. Also ten sentiments are analyzed in social networks in wich positivity, trust, and anticipation predominate. Greater attention to this issue is necessary both from the private initiative and from public policies, so that financial literacy is an effective tool for a more sustainable behavior by consumers. Finally, a new definition is proposed based on our findings.

Recibido (31/05/2022) Revisado (01/09/2022) Aceptado (30/09/2022) RESUMEN: Los conocimientos financieros favorecen la toma de decisiones financieras informadas de los individuos y, por extensión, contribuye a la adquisición de comportamientos financieros saludables que impulsan el bienestar financiero de la sociedad en su conjunto. Hasta la actualidad no se han encontrado unos indicadores generalizados mensurables que permitan valorar los niveles de competencias financieras. Esta investigación tiene como propósito analizar las producciones académicas que aportan datos empíricos y teóricos en la medición de los niveles de conocimientos financieros de la población, proporcionando una síntesis de los estudios, desarrollados desde 1940 que se basan, principalmente, en cuestionarios. Se lleva a cabo una simplificación de la declaración PRISMA que permite examinar a través de su evolución temporal las fuentes, los objetivos perseguidos, así como los hallazgos, conclusiones y recomendaciones para elevar los conocimientos financieros y para mantener hábitos que permitan alcanzar mejores cotas de bienestar material .Los resultados obtenidos coinciden en constatar las escasas competencias financieras de los evaluados desde el siglo pasado, principalmente de las mujeres, los jóvenes y aquellos que cuentan con menos recursos y menos formación, por lo que son necesarias iniciativas que permitan mejorar la formación de esta clase de capital humano.
