If You Live In These Cities, Don’t Breathe In
Air pollution causes an estimated seven million premature deaths every year according to the World Health Organization.
As Statista’s Niall McCarthy notes, the recently released IQAir AirVisual 2020 World Air Quality Report found that 15 of the world’s 20 worst-polluted cities are in India, though the worst affected city on the planet is actually in China.

The Western Chinese city of Hotan had an average PM 2.5 pollution level of 110.2 in 2020.
It was followed by a host of Indian cities including Ghaziabad, Bulandshahr and Bisrakh with PM 2.5 levels of 95 or higher.
Besides Hotan, three other non Indian cities appear on the list of the world’s most polluted and they are Manikganj in Bangladesh as well as Lahore and Bahawalpur in Pakistan.
Interestingly, due to the lockdowns imposed by governments around the world to counter the pandemic, many major cities across the world experienced reductions in annual PM2.5 levels in 2020 compared to 2019.
