A city of happy people will always mean something different to a five-year-old—who may expect places to play and opportunities to spend quality time with their parents, such as a quick return home from work—compared to a student, a corporate professional, or a senior citizen, all of whom have specific needs and expectations.

Therefore, it is not fair to establish a single city as the leader. It is more appropriate to recognize a group of cities committed to cultivating and growing happiness, where education, inclusive policies, the economy, mobility, environmental protection, access to green areas, and innovation are not only important components of official policies but are also evident in the solutions implemented. These solutions should be tangible for residents and have a direct impact on their quality of life.
