This article proposes moving toward a strengths-based view of aging, which recognizes that older adults can enact their social citizenship through participation in activities and places in the public space that they perceive as being culturally, personally, and socially meaningful. Using a Stockholm-based case study, it considers the need for spaces, places, and tools accessible to people who have cognitive decline to enable social citizenship, including age- and dementia-friendly communities. The case study, empirical research, and policy are discussed in relation to tools for mapping participation in a "smart"and digitalized society.
