The OECD is investigating how insurance can support the social security network and, in particular, long-term care and health care systems. Financing the long-term care and health care systems can be burdensome for countries and finding financing solutions that support fiscal budgets is an important consideration with ageing economies and demographic changes. This report is a stocktaking of long-term care and health care systems in OECD and non-OECD countries with a strong focus on the nature of the insurance markets that contribute to these systems.
