In this study I explore boundary work processes that older adults do which influences friendships among residents of a progressive care retirement community. Accounts of boundary work as mechanisms for including some and excluding other residents as potential friends were collected by using a combination of quantitative surveys and qualitative interviews from residents (age 65+) of a progressive care retirement community in the United States. First, a survey explored symbolic boundaries related to cultural capital, defined as music and leisure interest and participation, as well as structural and social aspects of friendships among residents (N=66). Second, in-depth interviews of a sub-sample of residents of an assisted living facility within the community (N=15), were conducted to examine older adults' narratives of how they use cultural capital as a mechanism of symbolic boundary work that influences their friendships with others in the retirement community. The administrator of the assisted living facility (N=1) was also interviewed. Findings from this study suggested that cultural capital was associated with sociability which offers some support for the relational "tool kit" model of the theory. However, findings from in-depth interviews suggested that while music and leisure interests and participation may be important, valuations of bodies were more likely to influence "othering" of residents, although the two are related. This study enriches our understanding of how symbolic boundary use varies by group and context, as well as makes theoretical contributions to the literature on symbolic boundaries by exploring the ways in which aging may alter the use of boundaries.
