Center for Strategic and International Studies: “Global Aging and the Sustainability of Public Pension Systems, released in January 2007, chronicles the efforts of twelve developed countries to prepare for their coming age waves—and in particular, to reform their public pension systems. The study contrasts and compares retirement systems in different countries, discusses recent reforms, and evaluates likely developments. It supplements the strictly quantitative conclusions of The CSIS Aging Vulnerability Index with a more qualitative analysis that takes into account differences in institutions, politics, and culture between countries.”
