The Perception of Environmental Problems and Quality-of-Life Deterioration in an Intermediate City: Evidence from Culiacán, Mexico

Urban sustainability research has increasingly emphasized the role of environmental conditions in shaping the quality of life; however, the empirical evidence for intermediate cities in developing countries remains limited, particularly from the perspective of citizens’ perceptions. This study examines the relationship between the perceived severity of environmental problems and the perceived quality-of-life deterioration in Culiacán, Mexico, an intermediate city characterized by climatic vulnerability and institutional constraints. Based on 552 face-to-face surveys, of which 546 contained complete information for index construction, a cross-sectional and predominantly quantitative design was employed. The environmental perception and quality-of-life deterioration indices were constructed as simple arithmetic averages from Likert scale items, without assuming a single latent construct. The quality-of-life deterioration index captures the perceived negative conditions affecting well-being rather than the quality of life itself; therefore, higher values indicate a greater perceived deterioration. A bivariate ordinary least squares regression was used to assess the association between both indices. The results show a positive and statistically significant relationship (β = 0.486, p < 0.001), with R 2 = 0.220, indicating that a greater perceived environmental severity is associated with a greater perceived deterioration of well-being. The water-related issues, particularly drought and water contamination, emerge as the most critical concerns. These findings highlight the relevance of environmental perceptions in urban well-being assessments in intermediate cities.
