700 million became account holders in 2011-2014. Mobile money in Africa helped also for a massive boost!
From 2011 and 2014, 700 million people became account holders at banks, other financial institutions, or mobile money service providers, and the number of unbanked individuals dropped 20 percent to 2 billion adults. “Access to financial services can serve as a bridge out of poverty. We have set a hugely ambitious goal – universal financial access by 2020 – and now we have evidence that we’re making major progress,” said World Bank Group President Jim Yong Kim. Between 2011 and 2014, the percentage of adults with an account increased from 51 percent to 62 percent, a trend driven by a 13 percentage point rise in account ownership in developing countries and the role of technology. In particular, mobile money accounts in Sub-Saharan Africa are helping to rapidly expand and scale up access to financial services.
