OECD Indicators

image of Health at a Glance 2021

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.

Demographic trends

In recent decades, the share of the population aged 65 years and over has nearly doubled on average across OECD countries, increasing from less than 9% in 1960 to more than 17% in 2019. Declining fertility rates and longer life expectancy (see indicator “Life expectancy by sex and education level” in Chapter 3) have meant that older people make up an increasing proportion of the population in OECD countries. Across the 38 OECD member countries, more than 232 million people were aged 65 and over in 2019, including more than 62 million who were at least 80 years old. As ageing represents one of the key risk factors for serious illness or death from COVID‑19, the pandemic has driven home the need to ensure that health systems are prepared to adapt to the changing needs of an older population.
