The Global Financial Inclusion (Global Findex) database, provides comparable indicators showing how people around the world save, borrow,make payments, and manage risk. The survey is conducted as part of the Gallup World Poll which targets a nationally representative, randomly selected sample from the non institutionalized population at or above the age of 15. The data will become available on a register to download basis in late 2015 at the World Bank’s microdataset repository.
