Background and Objectives 

Comprehensive definitions of social issues and populations can set the stage for the development of responsive policies and practices. Yet despite the rise of late-life homelessness, the phenomenon remains narrowly understood and ill-defined. 

Research Design and Methods 

This article and the definition that ensued are based on the reconceptualization of interview data derived from a critical ethnography conducted in Montreal, Canada, with older homeless persons (N = 40) and service providers (N = 20). 

Results 

Our analysis suggests that definitions of late-life homelessness must include 4 intersecting components: (1) age, eligibility, and access to services; (2) disadvantage over the life course and across time; (3) social and spatial processes of exclusion that necessitate aging in “undesirable” places; and (4) unmet needs that result from policy inaction and nonresponse. 

Discussion and Implications 

The new definition derived from these structural and relational components captures how the service gaps and complex needs identified in earlier works are shaped by delivery systems and practices whose effect is compounded over time. It provides an empirically grounded and conceptually solid foundation for the development of better responses to address homelessness in late life.
