To study children friendly environments, a possibility is to start from constructs as well-being or quality of life of children and then assessing the congruence between the indications coming from literature and the characteristics present in the environment. Another way is to recognise that children have a privileged role in the definition of the characteristics of an environment friendly for them. This is in line with art. 12 of the International Convention on Children’s Right that establishes the right of children to express an opinion about every matter of their interest.The aim of the present research is to contribute to a greater understanding of the concept of child friendliness (c.f.) starting from indications provided by different types of people residing in different places in Italy. In a study on how children in different disadvantaged communities evaluate their own urban environment, i.e., the replica of an analogous study conducted in the 1970s (Chawla, 2002), it emerged that the environmental characteristics/qualities identified as important in the 1970s were still significant 20 years later. Thus, on one side it is possible to speak about some constants in the way children relate to their own world (Lynch, 1977). We thought it would also be interesting to understand if and how the concept of child friendliness is articulated in relation to both place of residence and children's age and to explore this concept from other perspectives, i.e., in other phases of the life cycle (mothers and the elderly) or in professionals who work with children. Therefore, we contacted 360 subjects residing in three different Italian territorial contexts, i.e., in a neighbourhood in Rome (Montemario), in Nettuno (40,000 inhabitants) in central Italy, and in Caserta (82,000 inhabitants) in southern Italy. In each of these three places, 120 participants were contacted, subdivided as follows: 20 children 8-9 years of age and their mothers, 20 children 11-12 years of age and their mothers, 20 elderly and 20 professionals working in different ways in the childhood sector. The choice of the children is easily understandable. As to the other participants, they were chosen because in some way they are sensitive to the condition of children in the urban environment: the mothers were chosen because in Italy often they are still the main caregivers, the elderly because they are weak subjects in the city, just like children, and the professionals because they are in contact with the reality of childhood in their work. All participants had been residing (or working in the case of the professionals) in the area for five years. All were first administered a form in which they were asked to imagine the characteristics of a child friendly environment. Then they were interviewed about the reason of each point they made. We chose the interview as instrument because it was more suitable to the explorative aim of our research. It gave the chance to the participants to express freely their personal point of view. We are aware that what comes out is partial in a global work of individuation of child friendly environment indications. It is strongly biased by the aware dimension of opinion that people have on the topic examined. Worthy of note, however, is that children productions were very rich. They didn’t show particular difficulties to cope with a work of fantasy on a question not very well known.Using this comparative perspective, we will reflect on how the concept of child friendliness was articulated in our participants, i.e., on how homogeneous it was internally, on how it differed according to the different types of participants considered, and on how much this difference could be attributed to the different experience in the territory and/or to the characteristics of the territory. It will be interesting to reflect upon the similarity between the ideas of participants and what is desired at both a legislative and local/national political level. The opportunity to identify more structured methods to explore the phenomenon and the real possibility to use them will be a matter of reflection.
