But it is important to mention that proliferation of vehicles, rapid industrial growth and the population boom are considered the main causes of this situation.

How likely are people with respiratory illness to be aware of the IMECA index?
Results indicate that respondents with a respiratory illness themselves or in the home, compared to those who did not, were 14% more likely to be aware of the IMECA index. Respondents with a respiratory illness in the home were more likely to have had a healthcare provider discuss the Air quality index with them. Following the assessment of air quality index awareness, analyses considered whether those who knew of this resource modified their behavior to reduce exposure to air pollution. To gauge this application of IMECA knowledge among respondents, the number of days modified, defined as avoiding exercise or strenuous activity outdoors in response to poor air quality over a 12-month period, was assessed.
What is the most polluted city in the world?
In 1992, the United Nations named Mexico City " the most polluted city on the planet" and "the most dangerous city for children" six years later. From 1950 to 2015, the population in Mexico City increased from three million to twenty million. This population boom occurred mainly because of migrants that were looking for better opportunities, and as a consequence, the industrialization era began. This industrial growth was responsible for emitting over 11,000 tons of waste material into the atmosphere every day." As a result, the economy boomed as did the proliferation of vehicles. In 1980, there were 124 cars and light-duty trucks per 1000 residents. By 2010, there were 267." Population growth, increasing motorization and industrial activities, a constrained basin and intense solar radiation combined to cause intense air-quality problems of both primary and secondary pollutants. The automatic air-quality monitoring network, established in the late 1980s, revealed high concentrations of all criteria pollutants: lead, carbon monoxide, nitrogen dioxide, sulphur dioxide, ozone and particulate matter (PM). Ozone exceeded the air quality standards more than 90 percent of days and peaked above 300 parts per billion (about three times the standard) 40–50 days a year, among the worst in the world".
