Life looks vastly different for retirees around the world. Not only are jobs, cultures, and traditions varied, but the ways in which governments provide for old-age citizens differs greatly from place to place.

To compare and contrast retirement security in various countries, Natixis Investment Managers and CoreData Research examines four indicators that measure welfare in retirement to compile its annual Global Retirement Index (GRI):

Material well-being: income equality, income per capita, employment

Health: life expectancy, health expenditure per capita, non-insured health expenditure

Quality of life: happiness, air quality, water and sanitation, biodiversity and habitat, environmental factors

Finances in retirement: old-age dependency, bank nonperforming loans, inflation, interest rates, tax pressure, governance, government indebtedness

The 44 countries included in the index are 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 report notes that “countries with strong overall rankings tend to perform well in the finances sub-index,” including New Zealand, Switzerland, Australia, Canada, Iceland, and Ireland.
