Natixis

The Global Retirement Index (GRI) is a multi-dimensional index developed by Natixis Investment Managers and CoreData Research to examine the factors driving retirement security and to provide a comparison tool for best practices in retirement policy. The index includes International Monetary Fund (IMF) advanced economies, members of the Organization for Economic Cooperation and Development (OECD) and the BRIC countries (Brazil, Russia, India and China). The researchers calculated a mean score in each category and combined the category scores for a final overall ranking of the 44 nations studied.
