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.

Smoking among adults
Smoking is a leading cause of multiple diseases, including some cancers, heart attacks, strokes and respiratory diseases such as chronic obstructive pulmonary disease. Smoking among pregnant woman increases the risk of low birth weight and premature delivery. The World Health Organization (WHO) estimates that tobacco smoking kills 8 million people in the world every year. More than 1.2 million of these deaths are due to second-hand smoke and 65 000 are among children (WHO, 2020[1]). In 2019, tobacco smoking accounted for 200 million disability-adjusted life‑years worldwide (Reitsma et al., 2021[2]). Although the prevalence of smoking has decreased over the past 30 years, population growth has led to an increase in the total number of smokers, from 0.99 billion in 1990 to 1.14 billion in 2019 worldwide (Reitsma et al., 2021[2]).
