2018's World Air Quality Report was based on data gathered from over 3,000 cities around the globe. The report was made by measuring the levels of PM2.5 particulates (fine particles of a diameter of 2.5 micrometres in the atmosphere) in 2018. PM2.5 pollutants can enter deep inside the lungs and bloodstream of humans and have an adverse effect on their health.

The report also stated that Bangladesh, on average, was the most polluted nation, followed closely by Pakistan and India. While, Afghanistan, Mongolia, Bahrain and Kuwait topped the chart, countries like Iceland, Finland, Estonia, Australia and Sweden were among the least polluted as per the 2018's World Air Quality Report.

The report said, "The city ranking shows Asian locations dominating the highest 100 average PM2.5 levels during 2018, with cities in India, China, Pakistan and Bangladesh occupying the top 50 cities."

IQAir Chief Executive Officer Frank Hammes said, "The 2018 World Air Quality Report is based on the review, compilation and validation of data from tens of thousands of air quality monitoring stations around the world."

The data for the study was gathered from a wide range of government sources. IQAir AirVisual has included data from air quality monitors operated by private organisations and individuals.
