Summary

Urban vitality refers to the intensity, diversity and continuity of human activities within city spaces. It emerges from the interplay between the built environment, social dynamics and economic functions, and serves as both an indicator and driver of sustainable urban development. Thriving urban vitality supports economic resilience by fostering innovation, entrepreneurship and local commerce. It underpins social well-being through enhanced public life, community interaction and cultural exchange. Equally, it reflects environmental quality, as accessible green spaces, walkable neighbourhoods and efficient transport networks contribute to healthier, low-carbon cities. Research has advanced from single-metric assessments towards multidimensional, dynamic evaluations that integrate physical form, human behaviour and technological data streams. This holistic perspective informs urban planning strategies aimed at achieving inclusive, liveable and resource-efficient cities in the face of rapid urbanisation and climate change.

Technical terms

Urban vitality: The degree of lively human activity in urban areas, reflecting economic, social and cultural dimensions.

Built environment: Physical components of urban areas, including buildings, transport networks, public spaces and land-use patterns.

Deep learning: A subset of machine-learning methods using neural networks with multiple layers to extract complex features from data such as images or spatial metrics.

Multisource big data: High-volume, heterogeneous datasets (for example mobile-phone traces, social media check-ins, street imagery) combined to analyse urban phenomena in detail.

Social cohesion: The strength of relationships and sense of solidarity among members of a community, often linked to trust, participation and shared identity.
