Health at a Glance 2021
OECD Indicators
Health at a Glance provides a comprehensive set of indicators on population health and health system performance across OECD members and key emerging economies. These cover health status, risk factors for health, access to and quality of health care, and health resources. Analysis draws from the latest comparable official national statistics and other sources.
Alongside indicator-by-indicator analysis, an overview chapter summarises the comparative performance of countries and major trends. This edition also has a special focus on the health impact of COVID-19 in OECD countries, including deaths and illness caused by the virus, adverse effects on access and quality of care, and the growing burden of mental ill-health.

Dementia
Dementia represents one of the greatest challenges associated with population ageing. The term “dementia” describes a variety of brain disorders, including Alzheimer’s disease, which progressively lead to brain damage and cause a gradual deterioration of a person’s functional capacity and social relations. Despite billions of dollars spent on research into dementia-related disorders, there is no cure, and substantially disease‑modifying treatments may only now be emerging.
