This report reviews the state of literature on aging and homelessness. A substantial literature spanning several decades explores homelessness and the programs designed to address this issue (Lee, Tyler, & Wright, 2010; Shlay & Rossi, 1992; Toro, 2007; Trypuc & Robinson, 2009). However, present knowledge and practices about homelessness tend to focus on youth, younger adults, and young families, with far less attention to older people (Beynon, 2009; Burns, Grenier, Lavoie, Rothwell, & Sussman, 2012; Cohen, 1999; Crane & Warnes, 2001; Gonyea, Mills-Dick, & Bachman, 2010; McDonald, Dergal, & Cleghorn, 2004). Older people who are homeless are depicted as an ‘invisible population’ (Gonyea et al., 2010), but with demographic shifts the numbers of older people experiencing homelessness can be expected to rise (Edmonston & Fong, 2011). Population aging calls for research and policy attention to aging and homelessness.
