Air quality in the municipality of Irapuato, Guanajuato, Mexico, is one of the primary concerns of the state, largely due to the growth in industry and population. The objective of this research was to determine the willingness-to-pay (WTP) of Irapuato residents for improving environmental quality. The contingent valuation method was employed, utilizing a logit model based on data collected from surveys conducted among the inhabitants. A sample of 100 was obtained with the simple random sampling method. The results indicate that 90% of the respondents have a perception of air pollution as being between bad and very bad, while 10% perceive the air quality as good or very good. The average WTP obtained was 32.50 MXN per month per family. At higher levels of education and income, as well as among respondents who have had any disease related to environmental pollution, the willingness to pay for an improvement in air quality increased by 5.8%, 8.7%, and 12.8%, respectively. The above suggests involving the residents in the search for possible solutions.
