The Melbourne Mercer Global Pension Index compares retirement income systems in 18 countries representing more than half of the world’s population. The Index rates these systems based on their adequacy (accounts for 40% of the overall score), sustainability (35%) and integrity (25%). In 2012, Denmark tops the list with an “A” grade – the first “A” awarded since the Index was created in 2009.

“Many of the world’s retirement systems are under increasing stress with an aging population, low investment returns and, in some cases, significant government debt,” says Dr. David Knox, Mercer Senior Partner and author of the report. “Reform is needed to ensure that adequate benefits are provided over the long term in a sustainable manner.”

In addition to grading the retirement systems, he notes, “The Index report highlights several reforms relevant to each country that will provide improved results for individuals, households and the broader community.”
