What makes a city happy? Is it clean air, green parks, good governance, or a sense of community? In 2025, the answer may be: all of the above. This article explores the 5 happiest cities that exemplify these qualities.

This year, the Institute for the Quality of Life unveiled its eagerly awaited Happy City Index 2025, ranking over 250 global cities across 82 indicators in six major categories: Citizens, Governance, Environment, Economy, Health, and Mobility. These indicators offer a comprehensive snapshot of urban happiness and livability.

At the top of the list are five standout cities—each offering unique strengths in sustainability, infrastructure, and quality of life. But the Index also highlights interesting trends, especially in how Italian cities like Milan and Turin are beginning to close the gap with global leaders.

What is the Happy City Index?

The Happy City Index is an international benchmarking tool used by governments, planners, and citizens to evaluate how well a city supports the well-being of its inhabitants. It considers everything from urban safety, clean energy, and social cohesion, to mental health support, public transport, and access to culture.

While no single city claims the title of the absolute “happiest,” the five highest-scoring ones have earned a place in the prestigious Gold Cities list. These cities exemplify the future of urban living, combining progressive policy with human-centered design.
