According to a Los Angeles Times article, the report found that high air pollution levels threaten the health of 175 million people, about 58% of the population. But in California, the proportion is far higher: 91% of state residents, more than 33 million people, live in counties with poor air quality, especially in Southern California and the Central Valley.

Annually, California’s dirty air is estimated to cause 19,000 premature deaths, 9,400 hospitalizations and 300,000 respiratory illnesses.
