Time and collective historical experience loom large in the formation of generations. I argue that spatial proximity cements generational consciousness among seniors in Arizona retirement communities who identify themselves as members of the Second World War generation. The argument twins Karl Mannheim's social‐historical conception of generations and Hannah Arendt's political philosophy which underscores the space of appearance in the public realm in identity formation. It is through congregating, interacting and conversing on a daily basis that seniors in retirement enclaves affirm and reaffirm who they are, both to themselves and outsiders. I draw upon a suite of Arizona case studies, 1988–2000, in revealing ‘voices’ for a slice of the Second World War generation. Discussions revolving around family, community and national life reveal beliefs and values coalescing around four themes: (1) splendid isolation; (2) dissolution of values; (3) absence of children; and (4) fraying the social compact. The space of appearance within retirement enclaves engenders a strong sense of collective identity and belonging in ageing and, simultaneously, leads to questions about implications and consequences of intergenerational separation. I conclude with a poignant multigenerational experience as suggestive of the potency of intergenerational contact and exchange. Copyright © 2007 John Wiley & Sons, Ltd.
