The 2023 edition of Pensions at a Glance highlights the pension reforms undertaken by OECD countries over the last two years. It includes a special chapter focusing on pension provisions for hazardous or arduous work. It describes existing rules, characterises recent policy trends and assesses the design and functioning of early-retirement rules for hazardous or arduous jobs given changing working conditions and ageing pressure on pension systems. This edition also updates information on the key features of pension provision in OECD and G20 countries and provides projections of retirement income for today’s workers. It offers indicators covering the design of pension systems, pension entitlements, the demographic and economic context in which pension systems operate, incomes and poverty of older people, the finances of retirement income systems and private pensions.
