How Many People Globally Lack Access to Financial Services?

How many adults worldwide don't have access to basic financial services? And why does financial inclusion matter? The World Bank's Global Findex report answers these questions and more using Gallup World Poll data. Joe Daly, Gallup partner and manager of the worldwide project, explains the new report's findings and where disparities in financial inclusion still exist. Later, the recently passed tax reform law will have an impact on many Americans' taxes -- but most adults are unclear about how it will affect them.
