Last month, the World Bank released new data about how adults around the world use formal financial services. The good news: the number of people with a bank account grew by 700 million worldwide from 2011 to 2014. The bad news: of the remaining 2 billion people without a bank account, women are still disproportionately underserved. The gender gap of 7 percentage points did not budge from 2011 to 2014.
