The objective of the SMEF WG survey was to take stock of MSME definitions across AFI’s global network, identify what criteria was being used to define MSMEs and whether a special c policy informs these classifications. The survey has two phases. First, the survey was completed by individuals from AFI member institutions, who answered questions about how MSMEs are de ned in their countries and whether the definition is of official (i.e. defined by law or in a government policy). The second part of the study will take a closer look at country experiences to understand how comprehensive MSME definitions are and how they have been implemented. This will reveal the advantages and challenges of current definitions, how well they reflect the state of MSMEs in AFI member countries and whether the definitions need to be redefined.
