Ageing and urbanization bring major consequences and implications for all facets of human life. We see changes not only in terms of population structure and location, but also in living arrangements, family composition and family relations, economic dynamics in terms of growth, savings, investment and consumption, labour markets, pensions, taxation and intergenerational transfers, health and health care, housing and migration, voting patterns and representation, etc.Thus far, however, little discussion exists about the diversity and particularities of the urban ageing phenomena, how it affects and is affected by public policies, and implications for the construction of old age and the reconfiguration of the life-course structure.My research program aims to offer concrete tools and dialogue points with city planners (on its broader definition), which I consider to be the research field with great an untapped potential to contribute with knowledge and policy insights for the field of gerontology.
