In recent years, data sources for financial inclusion have become richer yet more complicated to navigate. On the demand side, there are numerous sources: The Global Findex was released in 2012; there are various country-level surveys like FinScope, FinAccess and the Financial Inclusion Tracker Survey (FITS) just to name a few. Similarly, the supply-side data sources have grown and deepened to include more focus on sub-national data and to cover more indicators.How do we navigate this busy data landscape? And what do the data sources tell us? Which data source do we use for what purpose? Ultimately, there is no single “best source” for data on financial inclusion. To know what data you need, you must start with asking yourself what you want to know.
