Previous studies have shown that friendly environments are associated with well-being and higher quality of life in older people. This study aimed to investigate the relationship between friendly environments and subjective well-being by segmenting the population according to the need for help in performing activities of daily living (ADLs) in a representative sample of people over 55 years of age in the Basque Country (Spain) (n = 2760). To determine the predictive power of friendliness on subjective well-being, two separate linear regression models were obtained according to the need for help in ADLs. The results obtained show a greater explanatory power of the model in the case of people who required help. However, in the case of people who do not need help, subjective health had a greater weight in the predictions. This paper's findings support the greater importance of the characteristics of the physical and social environment, as people's functional status worsens, with friendliness being an explanatory factor for people's well-being as they age and their dependency increases.
