Many of Asia's retirement-income systems are ill-prepared for the rapid population ageing that is underway. Asia's pension systems urgently need to be reformed to ensure that they are both financially sustainable and provide adequate retirement incomes. This report examines the retirement-income systems of 11 non-OECD economies in the region, comparing the results with a selection of OECD countries. The report provides new data for comparing pension systems of different economies. It combines the OECD's expertise in modelling pension entitlements with a network of national pension experts who provided detailed information at the country level, verified key results and provided feedback and input to improve the analysis.
