Air pollution is a health and environmental issue across all countries of the world but with large differences in severity. In the interactive map, we show death rates from air pollution across the world, measured as the number of deaths per 100,000 people in a given country or region.
In the State of Global Air 2024 interactive app, you can explore, compare, and download data and graphics reflecting the latest air pollution levels and associated burden of disease for over 200 individual countries, territories, and regions, as well as track trends from 1990 to 2021.
Almost all of the global population (99%) are exposed to air pollution levels that put them at increased risk for diseases including heart disease, stroke, chronic obstructive pulmonary disease, cancer and pneumonia.
This article published in the WHO bulletin in 2023, presents an overview of close to 50 years of WHO's activities in gathering air quality data and their use in global assessments and efforts to reduce health risks caused by air pollution.
See which health effects are included and how we calculate impacts. We invite you to view and compare the latest air pollution and health data, create custom maps and graphs, and download the images and data.
Air pollution consistently ranks among the top risk factors for death and disability worldwide. Breathing polluted air has long been recognized as increasing a person’s chances of developing heart dis - ease, chronic respiratory diseases, lung infections, and cancer. In 2017, air pollution was the fifth highest mortality risk factor globally
In order to produce global estimates at high resolution (0.1 grid‐cells), additional data is required. Annual urban mean concentration of PM2.5 is estimated with improved modelling using data integration from satellite remote sensing, population estimates, topography and ground measurements.
