Summary
Urban green space and GDP correlate with national happiness levels. Green space is key in wealthier nations, while GDP is more influential in less wealthy ones, with social support mediating the effect.
Area of Science:
- Urban planning and environmental psychology.
- Global public health and socioeconomic studies.
Background:
- Urban green space is linked to citizen well-being.
- Cross-national research on green space and happiness is limited.
Purpose of the Study:
- To investigate the relationship between urban green space (UGS) and national happiness levels across diverse socioeconomic conditions.
- To explore the mediating role of social support and moderating role of GDP in this relationship.
Main Methods:
- Quantified UGS using high-resolution satellite imagery for 90 cities in 60 countries.
- Analyzed correlations between UGS, GDP, and national happiness.
- Examined mediation by social support and moderation by GDP.
Main Results:
- Both UGS and GDP correlate with national happiness.
- UGS is uniquely associated with happiness in wealthier nations; GDP is key in less wealthy nations.
- Social support mediates the UGS-happiness link, and GDP moderates it.
Conclusions:
- Maintaining urban green space is crucial for citizen happiness, particularly in wealthier countries.
- Urban green spaces serve as vital hubs for social cohesion, enhancing well-being.
- Policy should consider both green infrastructure and economic factors for national happiness.

This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being.

Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...
