With intensifying competition in the financial system, new strategic applications are constantly being devised in the search for greater efficiency. In consequence, decisions are commonly based on locating and retaining market segments with high added value, and those which fail to supply the profitability required by the market are “excluded”. The aim of this study is to analyse the research advances made in the field of financial inclusion and the main lines of investigation currently being addressed by means of a bibliometric analysis. Among the scientific community, there is growing interest in this study area. The most assiduous in this respect are SA Asongu (the most productive author), Enterprise Development and Microfinance (the journal that has published the most articles in this field), Makerere University, Uganda (the most productive institution) and India (the country where most recent studies have taken place). Foreseeably inspiring future research, there is currently great interest in developing a more accessible financial system, especially through the use of digital money (Fintech) as an instrument to promote financial inclusion. For all this, a line of research is proposed that also includes the proposals from the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals.
