Includes regulatory-grade and sub-regulatory grade monitoring stations operated by governments, educational facilities, researchers, non-profit organizations, corporations and individuals.
Right now 90.1% (6,777,953,432 people) of the global population are experiencing ambient air quality that does not meet the WHO annual PM2.5 guideline.
The 20-39 age group is currently most affected by air pollution.
Exposure distribution by age group
Real-time comparison of age group exposure to WHO annual PM2.5 guideline and interim targets.
Data from air monitors is presented within the context of the WHO recommended annual air quality guideline levels and interim targets for PM2.5. These guidelines help to determine which cities and regions are most impacted by the health risks of PM2.5 in the hope to encourage local actions to help improve air quality and work toward meeting the WHO guideline and interim targets.
Seven color bands are used to provide an easy identification of multiples of the 5 µg/m³ WHO PM2.5 guideline, and the interim target levels.

This interactive map is designed to demonstrate the power of aggregated air quality data, the significance of crowd sourced air quality data to fill the global air quality data gap and provide a global context for outdoor air pollution exposure.
The data is a global aggregation of publicly available PM2.5 data from ground-level measurements conducted by governments, researchers, NGOs, community groups, enterprises and citizens through an network of evolving collaborations, contributions and partnerships.
