Claiming the hypothesis of the positive relationship between air pollution and urbanization, the results of this analysis comply with the findings of the previous literature. Sample size consists of 45 countries randomly chosen from the IQAir website. The limitations of this analysis are acknowledged at the end with further recommendations for future research
