This link will take you to a video of a four-hour aging in a place symposium that addresses many intersecting issues that concern planners, architects, policy makers, senior services and other groups. It is an excellent look at research studies, projects and challenges related to housing a growing senior population.

Major topic areas include Thinking and Doing Where Aging, Inequality, and Spatial Justice Meet; The Just City in the Aging Society: Identifying Values to Support Better Design; Ideals VS Reality; Aging Well in a Place: Bringing a Spatial Justice Lens to the Age-Friendly Movement; Aging Well in the City: Values Supporting Policy, Practice, and Public Life.
The brochure description produced by the Joint Center for Housing Studies Harvard University is quoted below.
“The United States is an aging society with growing economic inequality and socio-cultural diversity. Age-associated disadvantages, such as declining health, overlap with unequal access to healthy places, suitable housing, and other social determinants of health. These have in many cases affected people throughout life. As a result, there are vast differences in people’s experiences of late life. “Today, public discussion and policy focuses on “aging in place” as a way to improve quality of life and reduce costs. However, in part because of socioeconomic differences and structural inequalities, not all older adults can live in or move to age-supportive communities, neighborhoods, or homes that match their values and needs. Differences in access to places to age well can take the form of spatial inequalities, such as inadequate market rate housing for older adults on fixed incomes.
“Co-sponsored by The Hastings Center, the symposium will apply a spatial justice lens to this challenge, asking, who has access to age-friendly communities, accessible housing to prolong independence, and sufficient funds to cover housing and care? How can planners, policymakers, designers, and citizens make progress on social inequalities among older adults through planning and design? How can the fields of medicine, public health, and planning/design work together to effect change?”
