This report provides an overview of air pollution levels and associated health impacts in cities around the world. Since urban areas are often hotspots for poor air quality, city-level data can help to inform targeted efforts to curb urban air pollution and improve public health. This report draws on data from the Global Burden of Disease project [2] and from peer-reviewed analyses led by Susan Anenberg of the George Washington University.

A collaboration of the Health Effects Institute [4] and the Institute for Health Metrics and Evaluation’s Global Burden of Disease project [2], the program gives citizens, journalists, policymakers, and scientists access to high-quality, objective information about air pollution exposure and its health impacts. All data and reports are free and available to the public.
