Parents' Perceptions of the Neighbourhood Built Environment Are Associated with the Social and Emotional Development of Young ChildrenThe influence of the neighbourhood built environment on young children's physical development has been well-documented; however, there is limited empirical evidence of an association with social and emotional development.
