ABSTRACT Background: Placemaking advocates claim that high-quality public spaces enhance community well-being, yet empirical evidence quantifying this relationship remains limited, particularly in Global South contexts where informal neighborhood markets serve critical social and economic functions. Objective: This study examines the relationship between placemaking intensity and multidimensional community well-being in urban neighborhood markets, testing whether perceived place quality predicts psychological, social, emotional, and environmental well-being outcomes. Methods: We surveyed 1,200 users across three neighborhood markets in Lucknow, India, measuring placemaking quality via a validated Placemaking Index (PI) and well-being across four dimensions: psychological (safety, stress reduction), social (connectedness, cohesion), emotional (attachment, happiness), and environmental (sensory comfort, ecological quality). Hierarchical multiple regression tested PI's predictive power after controlling for demographics. Mediation analysis examined pathways through which specific placemaking dimensions influence well-being. Threshold analysis identified PI cut-points associated with meaningful well-being differences. Results: PI demonstrated a strong positive correlation with overall well-being (r = .73, p < .001). Hierarchical regression revealed that demographic variables explained minimal variance (R² = .019, p = .082), while PI uniquely accounted for 46.4% of well-being variance (β = .68, p < .001). When disaggregated, Overall Sense of Place emerged as the strongest predictor (β = .28, p < .001), followed by Social Sense of Place mediated 52% of the PI → Emotional Well-being effect. Threshold analysis revealed non-linear gains: markets with PI ≥ 75 showed 43% higher well-being scores compared to markets with PI < 66. Conclusions: This study provides robust quantitative evidence that placemaking intensity substantially predicts community well-being, independent of demographic characteristics. The findings validate placemaking's social impact claims and identify specific dimensions—particularly emotional attachment and social connection—as critical pathways. Results support policy arguments for placemaking investments as strategic interventions for enhancing urban quality of life and demonstrate the value of well-being outcomes as evaluation metrics for spatial interventions in Global South cities.
