BACKGROUND AND OBJECTIVES: Circumstances more common with aging may challenge the ability for older adults to maintain appropriate housing. The objective of this scoping review was to identify the risk factors and conditions associated with homelessness in older adults.

RESEARCH DESIGN AND METHODS: We searched OVID, CINAHL, Embase, PsycINFO, CENTRAL, and Social Works Abstracts from inception to February 2023. We included studies of older adults (defined as 50 years of age or older) or completed subgroup analyses accounting for older adults. We mapped the risk factors and conditions using an ecological framework (individual, relational, and structural/societal components).

RESULTS: Sixty-five studies were included. Individual factors included identifying membership in a racialized group, and experiencing psychiatric illnesses or substance use disorders. Relational factors included being unmarried, relationship breakdown, and adverse childhood events. Structural factors included the lack of affordable housing or income supports, and systemic discrimination. Those experiencing first-onset late life homelessness were more likely to be female, had relative lifelong socioeconomic stability, but experienced sudden relational or economic changes. Those experiencing chronic homelessness were more likely to be male, often facing persistent structural vulnerabilities with comorbid substance use or psychiatric disorders. Important research gaps include measures of social support, and age and sex disaggregated analyses.

DISCUSSION AND IMPLICATIONS: Key individual, relational, and structural factors are associated with homelessness in older adults. Adverse experiences and structural factors such as social losses and isolation have important implications towards the risk of homelessness at different stages in life. Further research evaluating age-appropriate interventions is paramount.
