GTFS: Global Trends and Future Scenarios Index

The Global Aging Preparedness Index

[PDF]

In this 2010 publication, authors Richard Jackson, Neil Howe, and Keisuke Nakashima explore the phenomenon of global aging and present the Global Aging Preparedness (GAP Index) “to provide a comprehensive assessment of the progress that countries are making in preparing for global aging, and particularly the ‘old-age dependency’ dimension of the challenge.” The index covers 20 countries, including most major developed countries and a selection of emerging markets for which data was available. To capture the full impact of this demographic transformation, the projection horizon of the index extends to the year 2040.
