The publication of the 2017 Global Findex has generated much reflection on the state of financial inclusion – and plenty of analysis of the data, looking for the buried treasure of some new trend or pattern. This yields important insights. "The Financial Inclusion Hype vs. Reality report" by the Center for Financial Inclusion (CFI) is particularly worth reading for its in-depth and honest reflection of what Findex tells us. But when using Findex, there are important things to keep in mind. First, while the overall figures and trends are important, the numbers for any one country should be treated with caution. This is not because we mistrust the Findex team or their work. It’s simply the result of what Findex is – a set of surveys based on randomly selected (hopefully representative) population samples of more than 150,000 adults in over 140 economies. And surveys can – and often do – go wrong, particularly when they deal with difficult or personal subjects (like finance) or are conducted in countries undergoing political and economic turmoil. This reality forms the backdrop of our work at the Microfinance Index of Market Outreach and Saturation (MIMOSA) project, which since last year has been supported by a strategic partnership with e-MFP. A huge part of MIMOSA is collecting and comparing data – from credit bureaus, microfinance and banking associations, central banks, third-party surveys like Findex, and our own field surveys.
