<p>Social well-being extends beyond income and life satisfaction, yet limited evidence exists on how its dimensions are organized in lived experience. This research reconstructs how people in Mexico articulate and prioritize the dimensions of social well-being. Based on a qualitative design with in-depth interviews (<i>N</i> = 247) conducted across four states and analyzed through Thematic Co-occurrence Analysis (TCA), the study examines three dimensions: objective, subjective, and community well-being. The findings reveal a hierarchical configuration in which objective well-being, particularly nutrition, emerges as the most grounded dimension, followed by community well-being, centered on social capital and the built environment. Subjective well-being, while clearly present, appears less central, and happiness shows greater relevance than life satisfaction. Participants integrate material conditions, emotional states, and neighborhood contexts into unified narratives rather than treating them as isolated domains. These results contribute to debates on multidimensional well-being measurement by showing that dimensional hierarchies are socially constructed and territorially embedded rather than analytically fixed, challenging frameworks that assign uniform weights across populations and contexts and underrepresent community-level dimensions. The findings point to the need for measurement instruments that incorporate social capital and neighborhood quality as constitutive components of well-being, with implications for Mexico and other middle-income countries in the Global South.</p>
