Pensioners in Japan enjoy some of the highest standards of living in the world, according to a global ranking released on Wednesday.

The Global AgeWatch Index rated the country ninth out of 96 countries across a range of indicators, including life expectancy, income, welfare and facilities available to those aged over 60.

Japan leads the way in Asia and the report notes that it "has recognized the scale of the challenges presented by its aging population and begun to implement a broad range of policies in response, from employment to long-term care."

The report shows Japan at the top in terms of life expectancy and psychological wellbeing, while also noting that elderly people are valued in the workplace. But Japan does not rank so highly on its pensioners' income security.

Norway came in at the top of the index overall, followed by Sweden. The United States came in eighth and Britain 11th. China ranked 48th, while South Korea came 50th. Afghanistan came in last.

London-based HelpAge International compiled the report by looking at data from a range of international organizations. The group hopes the findings will help inform governments and improve the quality of life for elderly people.

HelpAge International — which has a network of affiliated organizations across the world — works to help older people claim their rights, challenge discrimination and overcome poverty.
