A healthy city is defined by a process, not an outcome.
A healthy city is not one that has achieved a particular health status.
It is conscious of health and striving to improve it. Thus any city can be a healthy city, regardless of its current health status.
The requirements are: a commitment to health and a process and structure to achieve it.
A healthy city is one that continually creates and improves its physical and social environments and expands the community resources that enable people to mutually support each other in performing all the functions of life and developing to their maximum potential.
WHO/Europe recommends a basic model for a healthy city.
