According to the World Health Organization, 92% of the world’s population is living with unsafe levels of air pollution, and more than 7 million premature deaths annually are linked to polluted air. The world’s population was estimated to have reached 7.8 billion as of March 2020. However, over 70 percent of the world’s population lives in the top 20 most populous countries. Thus, comparing air quality among these countries may be important.
IQAir published the 2019 World Air Quality Report on 25 February 2020. This report presents PM2.5 data made publicly available during 2019 to highlight the state of particulate pollution around the world. The following chart compares the PM2.5 data for the top 20 most populous countries.
