Exactly one year before the presidential election, the Washington-based Brookings Institution this morning launched “Blueprint for American Prosperity,” a “multi-year initiative to promote an economic agenda for the nation that builds on the assets—and centrality—of America’s metropolitan areas.”  MassINC will serve as a partner in this effort to identify key federal roles in everything from transportation policy to higher education programs that can help build a strong and diverse middle class.  This map lets you click on a state to view a profile of its major metropolitan areas.
