Habitability is a good indicator, from a psychological perspective, of the quality of life enjoyed by older people living in urban environments. Quality of life depends, among other factors, on living conditions together with activities of daily living. Such activities indicate an older person's degree of dependence and, therefore, the extent to which their home needs to be adapted and made suitable for them. The aim of this study is to analyse quality of life and satisfaction with life among older people in urban environments. The results indicate that the habitability conditions of homes are a predictive factor for satisfaction with life among older people, which is, in turn, linked to their level of autonomy. It would be interesting for future research to design and develop a protocol of social and psychological indicators of habitability capable of optimizing quality of life for older people living in urban environments.
