Introduction
Housing is an important determinant of health, and poor housing conditions have been linked to a variety of physical and mental health conditions (Krieger & Higgins, Reference Krieger and Higgins2002). Across North America, a growing number of older adults have a core housing need and live in substandard housing (Government of Canada, 2019; Joint Center for Housing Studies, 2019). For older low-income renters, affordability is the main concern. In Canada, housing is considered affordable if it costs less than 30 per cent of before-tax household income. Almost 20 per cent of older adults in Canada experience a housing affordability issue (Canada Mortgage and Housing Corporation, 2020); this rate was doubled for older adults living alone (Canada Mortgage and Housing Corporation, 2020), and disproportionately impact older adults in urban centres, and those who are visible minorities and recent immigrants (Clark, Reference Clark2005). Affordable housing programs are therefore critical for helping older Canadians access housing.
Affordable housing is a broad term that can encompass housing provided across the continuum, ranging from temporary housing to home ownership (Canada Mortgage and Housing Corporation, 2018a). Social housing is a subset of affordable rental housing (sometimes referred to as subsidized or public housing) that provides financial support to tenants, as rents are geared-to-income (RGI) and/or supplemented with subsidies (Housing Services Corporation, 2014).
Although subsidized households are increasingly made up of older adults, most social housing programs for older people are limited. For example, recent statistics in the United States show that the percentage of subsidized renters who are over age 65 has risen 5 percentage points to 35 per cent over the past 10 years (Joint Center for Housing Studies, 2018), yet the supply of housing assistance for older renters continues to serve only one in every three eligible older adults (U.S. Department of Housing and Urban Development, 2018). Therefore, it is no surprise that social housing waitlists comprise primarily of older people (Housing Services Corporation, 2012; National Low Income Housing Coalition, 2016). In Canada, the percentage of older adults on the waitlist has increased 10 per cent over the past decade, and wait times have doubled (Ontario Non-Profit Housing Association, 2016a). In fact, the social housing system in Ontario has been described as a “seniors housing system” because it is as large as Ontario’s long-term care system (Ontario Non-Profit Housing Association, 2015): 75,000 low-income older adults across the province live in a social housing community, and there are another 50,000 on the waitlist (Ontario Non-Profit Housing Association, 2015).
While social housing programs were created to support low-income older adults and families who can live independently, older people living in social housing increasingly require access to home care and support services to maintain their health and independence (Redfoot & Kochera, Reference Redfoot and Kochera2004). Furthermore, older adults on the waitlist for social housing experience poor health outcomes (Carder, Kohon, Limburg, & Becker, Reference Carder, Kohon, Limburg and Becker2018; Carder, Luhr, & Kohon, Reference Carder, Luhr and Kohon2016), and a growing number of vacancies in social housing are filled by tenants who identified as being vulnerable (Ontario Non-Profit Housing Association, 2015). In response, some social housing providers across Canada and the United States integrate health and support services for tenants, such as personal care, housekeeping, meals, and health and wellness services (see Canadian Urban Institute, 2020, for review); however, these are usually funded separately from housing and may only be offered to some of the residents. For example, in Ontario, social housing providers may have a subset of units dedicated to supportive housing that are funded by the Ministry of Health and facilitated by a health service partner (Ontario Non-Profit Housing Association, 2015); however, the availability of rent-subsidized supportive housing units is limited with long wait times (Ontario Non-Profit Housing Association, 2016b).
In the past 10 years, governments have made substantial investments to increase affordable housing options for low-income older adults. For example, the Canadian federal government invested $1.9 billion from 2011–2019 to improve affordable housing options for older adults and persons with disabilities (Canada Mortgage and Housing Corporation, 2018b), with a focus on increasing supply of affordable options and improving the quality of existing housing stock. Canada’s National Housing Strategy (Government of Canada, 2017) also prioritizes the housing needs of older adults by developing a variety of programs that will provide homes that are affordable and that meet their changing needs as they age in place:
The proposed National Housing Strategy approach will reduce housing needs for seniors by providing rental support through the Canada Housing Benefit. Affordability for low-income seniors living in community housing will be protected through the community housing initiatives and funding to provinces and territories. The National Housing Co-Investment fund will also support the construction, repair, and renewal of housing units for seniors, which is expected to relieve affordable housing demand among low-income seniors. In addition, the Fund will invest in affordable housing and will support partnerships with services to allow seniors to age in place. (Government of Canada, 2017, p. 25)
The National Housing Strategy (Government of Canada, 2017) is also invested in the sustainability of community housing programs (including social housing), which includes repairing and renewing existing housing stock and expanding the supply of community housing to ensure that low-income households (including older adults) can live in vibrant, inclusive communities.
While there has been an abundance of research on older tenants dating back to the inception of social housing, there has been no attempt to scope this literature to gain an overall picture of the current state of the evidence and gaps in knowledge. As this field of research spans several decades and thus reflects different social and policy priorities, it is important to identify key areas of research that may need updating to reflect the current needs of older adults in social housing. Given the rising demand to create and implement programs to ensure housing stability for low-income older adults living in social housing (Canadian Urban Institute, 2020; Joint Center for Housing Studies, 2019; Locke, Lam, Henry, Brown, & Abt Associates, 2011), it is necessary to identify the vulnerabilities that older tenants may face that place their housing at-risk and the strategies that social housing providers use to promote successful aging in place. Therefore, the aims of this scoping review were to map the literature on the characteristics of older adult tenants living in social housing, to identify factors that impact their housing stability, and to scope the strategies that were used by social housing providers to tackle these risks. Such insights enhance the ability of researchers and policy makers to develop new strategies to support low-income older adults to age in place in social housing contexts.
Methods
A scoping review was selected to describe the characteristics of older adult tenants, the factors that put their housing at risks, and the available social housing services to support aging in place. Whereas systematic reviews aim to assess the quality of evidence (Munn et al., Reference Munn, Peters, Stern, Tufaranu, McArthur and Aromataris2018), scoping reviews map the literature to examine how research has been conducted in a specific field, to identify key characteristics of a particular concept, and to articulate gaps in knowledge to inform future research and policy directions (Arksey & O’Malley, Reference Arksey and O’Malley2005; Munn et al., Reference Munn, Peters, Stern, Tufaranu, McArthur and Aromataris2018). As shown in Supplemental Table 1, our scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (Tricco et al., Reference Tricco, Lillie, Zarin, O’Brien, Colquhoun and Levac2018) to ensure methodological rigour and clear reporting; a study protocol was registered with Open Science Framework and can be accessed at https://osf.io/m8wru.
Eligibility Criteria
Eligible studies selected for review included those with urban-dwelling adults ages 55 and older who were living independently in rent-subsidized social housing that reported on (a) physical, mental, and social health characteristics of older tenants; or (b) characteristics of social housing service models that impact aging in place, such as housing policies, staff levels, and provision of on-site services. All included studies were full-text, peer-reviewed articles using either quantitative, qualitative or mixed methods that were available in English, with no location or publication date restrictions.
Studies were excluded if they had no policy or programming implications for social housing programs for older adults, as well as if they focused on older adults that (a) were experiencing homelessness; (b) were on the waitlist for social housing; (c) were relocating out of social housing due to redevelopment (e.g., gentrification); or (d) lived in private dwellings, market-rent apartments, retirement communities, assisted or sheltered housing with supports, or long-term care or nursing facilities. Given that housing affordability disproportionately impacts older adults in urban settings (Clark, Reference Clark2005), this review excluded studies on social housing in rural communities. Studies on affordable housing were also excluded; although rents are often below market-rent to be affordable to low- and moderate-income households, rents are not subsidized, and ongoing government financial assistance is not typically included (Housing Services Corporation, 2014). Finally, literature reviews and commentaries were excluded.
Information Sources and Search Strategy
The following databases were searched to July 2019: PsycINFO, Social Work Abstracts, MEDLINE, Embase, CINAHL, AgeLine, and Sociological Abstracts. Search strategies for each database were developed in consultation with an academic librarian and were translated to reflect each platform’s vocabulary and search fields. Controlled vocabulary and text words were used to search for concepts related to “older adults” and “social housing”. The full PsycINFO search strategy is provided in Supplemental Table 2. Additional records were identified through a hand search of the reference list of all included studies.
Study Screening
Covidence systematic review software was used to facilitate the screening process. Titles and abstracts were screened by two independent reviewers to assess relevance. Full-text articles were then reviewed by two independent reviewers to assess final inclusion. Discrepancies were resolved by consensus after discussion.
Data Charting
Based on Arksey and O’Malley’s (Reference Arksey and O’Malley2005) framework, a data charting form was used to extract information on authors, year of publication, location, social housing type, study design, purpose and/or intervention, building and tenant characteristics, and key findings. Key findings were reviewed and mapped onto various housing topics as they pertained to the characteristics of older tenants and social housing service models. These topics were developed through a discussion based on emerging themes across articles. Following a calibration exercise, two reviewers independently extracted data from all articles, and discrepancies were resolved through a discussion.
Results
A total of 7,171 articles were located. After removing duplicates, 3,925 titles/abstracts were screened, and 436 records were identified for a full-text review. In total, 290 records did not meet the inclusion criteria; therefore, 146 articles were eligible and included in this review (see Figure 1). Studies were predominately conducted in the United States (80.8%) and Canada (9.6%) and were published between 1964 and 2019. As shown in Figure 2, there has been a steady increase in publications over the past five decades, with a first peak in the 1980s and again in the 2010s, with over one-third of included studies published between 2010 and 2019. An overview of all included studies is provided in Supplemental Table 3.

Figure 2. Year of publication.
The majority of included studies were cross-sectional surveys (55.5%) and 10.3 per cent followed tenants longitudinally, most commonly to profile the characteristics of tenants, to understand the prevalence of certain health conditions (e.g., psychiatric conditions), or to examine factors associated with a particular health (e.g., hospital admissions) or housing (e.g., perceptions of safety) outcome. One fifth of studies evaluated the outcomes of health interventions (e.g., health screening programs, interprofessional health care teams) and recreation programs (e.g., Tai Chi) through randomized controlled trial designs, pre- and post-comparisons (with or without a comparison group), and process/outcome evaluations. The remaining studies consisted of qualitative observations, interviews and focus groups (8.9%), mixed methods (2.7%), and secondary data analyses (2.1%); one study also used geographic information system (GIS) mapping to conduct a spatial analysis of neighbourhood resources (Park, Cho, & Chen, Reference Park, Cho and Chen2019).
As shown in Figure 3, almost all studies (85%; n = 124) examined socio-demographic and health characteristics of older tenants, including physical, mental, and social health outcomes. Just under three-quarters of studies (72%; n = 105) reported on characteristics of social housing service models, most commonly focusing on the provision of on-site services; however, other topics such as building and unit condition, housing policies, staffing, and safety and security were also examined. Given the breadth of included studies that span several decades, Supplemental Table 4 provides a summary overview of the research topics discussed in each study, while the following results summarize key findings, referring to the most recent or relevant articles.

Characteristics of Older Adults in Social Housing
Older tenants in social housing experienced a variety of economic, health, and social inequalities. Most were women in their seventies who lived alone and had very low education and income levels. Approximately one-fifth of older tenants were also food insecure (Parton et al., Reference Parton, Greene, Flatley, Viswanathan, Wilensky and Berman2012), and many had low intake of fruits and vegetables (e.g., Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019; Noonan, Hartman, Briggs, & Biederman, Reference Noonan, Hartman, Briggs and Biederman2017), leading to nutritional deficiencies (e.g., Harris, Soteriades, Coolidge, Mudgal, & Dawson-Hughes, Reference Harris, Soteriades, Coolidge, Mudgal and Dawson-Hughes2000). The majority of older tenants reported fair or poor health; most had multiple chronic health conditions (e.g., Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019), low health literacy (Agarwal, Habing et al., Reference Agarwal, Habing, Pirrie, Angeles, Marzanek and Parascandalo2018), and reported taking an average of eight prescription medications (e.g., Pater, Agimi, & Albert, Reference Pater, Agimi and Albert2014). Vision and hearing problems were also common (e.g., Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019), and around one-quarter experienced cognitive impairment (e.g., Cotrell & Carder, Reference Cotrell and Carder2010).
In addition to poor physical health, studies showed that around half of older tenants experienced pain, had low mobility and physical activity levels, and reported difficulty doing their usual activities (Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019). Furthermore, up to half reported problems with (instrumental) activities of daily living (Gibler, Reference Gibler2003; Robbins et al., Reference Robbins, Rye, German, Tlasek-Wolfson, Penrod and Rabins2000). Although some older tenants had adult children (Chi, Yuan, & Meng, Reference Chi, Yuan and Meng2013; Sanders, Stone, Meador, & Parker, Reference Sanders, Stone, Meador and Parker2010) and/or close neighbours to provide support for daily activities (Sanders et al., Reference Sanders, Stone, Meador and Parker2010; Sheehan, Reference Sheehan1986b), over one-quarter had limited family support (Sanders et al., Reference Sanders, Stone, Meador and Parker2010) and most neighbours wanted to help only on a short-term basis (Sheehan, Reference Sheehan1986b). Therefore, many older tenants lacked informal networks to offer support, and declining physical functioning and reduced ability to carry out daily activities were the main reasons older tenants voluntarily moved out of their units (Bernstein, Reference Bernstein1982; Weinberger, Darnell, & Tierney, Reference Weinberger, Darnell and Tierney1986).
Loneliness was prevalent among older adults in social housing, with rates as high as 40 per cent (e.g., Gonyea, Curley, Melekis, & Lee, et al., 2018; Gonyea, Curley, Melekis, Levine, & Lee, Reference Gonyea, Curley, Melekis, Levine and Lee2018; Taylor, Wang, & Morrow-Howell, Reference Taylor, Wang and Morrow-Howell2018; Wee et al., Reference Wee, Tsang, Yi, Toh, Lee and Yee2019). Three-quarters of tenants also expressed a desire for more opportunities to build new relationships (Cotrell & Carder, Reference Cotrell and Carder2010), and between 31 per cent and 60 per cent reported feeling socially isolated, left out, and a lack of companionship at some or all of the time (Taylor et al., Reference Taylor, Wang and Morrow-Howell2018).
Poor mental health and substance use disorders were common, and changes in mental health status were a leading cause of eviction among older tenants (Bernstein, Reference Bernstein1982). Psychiatric conditions impacted approximately one-third of older tenants (Noonan et al., Reference Noonan, Hartman, Briggs and Biederman2017); mood disorders were the most common (e.g., Cotrell & Carder, Reference Cotrell and Carder2010; Robbins et al., Reference Robbins, Rye, German, Tlasek-Wolfson, Penrod and Rabins2000; Robison et al., Reference Robison, Schensul, Coman, Diefenbach, Radda and Gaztambide2009), with one-quarter to one-third reporting depression and up to 50 per cent reporting depression and anxiety (Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019). Additionally, one-quarter had substance use disorders (Rabins et al., Reference Rabins, Black, German, Roca, McGuire and Grant1996).
Hospital admissions and emergency department (ED) visits among older tenants were also high, with one-quarter to one-half being admitted to the hospital in the past year (Pater et al., Reference Pater, Agimi and Albert2014; Weinberger et al., Reference Weinberger, Darnell and Tierney1986), and 11 per cent using the ED as their main source of health care (Parton et al., Reference Parton, Greene, Flatley, Viswanathan, Wilensky and Berman2012). Furthermore, although the frequency of nursing home placements was relatively low (4% over a 28-month period; Smith Black, Rabins, & German, Reference Smith Black, Rabins and German1999), they were the third most common reason that older tenants voluntarily moved out of their units (Bernstein, Reference Bernstein1982) and were usually precipitated by the tenants’ declining physical and mental health and/or an inability to carry out daily activities (Weinberger et al., Reference Weinberger, Darnell and Tierney1986).
Characteristics of Social Housing Service Models
Unit condition
Social housing buildings tended to be built between the 1950s and 1970s, and units were small (less than 50 square metres) one-bedroom apartments with a bathroom and kitchen. Early studies found that older adults in social housing had higher housing satisfaction than those living in the community (Carp, Reference Carp1976); however, these studies were conducted within eight years of the housing complex being built, where amenities were still modern. Other research suggested that older tenants in subsidized rental housing were more likely to rate their housing conditions as fair or poor (Gibler, Reference Gibler2003), and that the units may not meet their cultural (Seo & Mazumdar, Reference Seo and Mazumdar2011) or accessibility needs (Fox et al., Reference Fox, Kenny, Day, O’Connell, Finnerty and Timmons2017; McCunn & Gifford, Reference McCunn and Gifford2014). Those living in non-accessible units were concerned about their unit’s ability to accommodate their needs as they aged in place (McCunn & Gifford, Reference McCunn and Gifford2014), and older tenants identified several accessibility features that their unit urgently needed, including bathroom aids, front door spyholes and keychains, intercoms, adequate storage for mobility aids, and parking/charging stations for mobility scooters (Fox et al., Reference Fox, Kenny, Day, O’Connell, Finnerty and Timmons2017).
Housing policies
Housing policies discussed in the literature were primarily focused on eligibility and retention. While some housing providers noted obvious age and income restrictions (e.g., Jacobs, Reference Jacobs1969; Suggs, Stephens, & Kivett, Reference Suggs, Stephens and Kivett1986), many had “independent living” clauses (Heumann, Reference Heumann1988; Sheehan, Reference Sheehan1986a) that focused on performance of daily activities (Bernstein, Reference Bernstein1982; Suggs et al., Reference Suggs, Stephens and Kivett1986). Housing providers with strict policies had limited involvement in managing tenant well-being, while those with more flexible policies tended to monitor independence and service use, and track changes in medical status (Sheehan, Reference Sheehan1986a). For these buildings, frail, older tenants who were accessing formal or informal in-home supports were often allowed to stay in their units, even with declining physical functioning (Sheehan & Wisensale, Reference Sheehan and Wisensale1991). Despite having independent living clauses, few building managers used them to evict an older tenant (Heumann, Reference Heumann1988); in cases where older tenants were asked to leave, it was predominately due to their declining mental health and/or posing a safety risk to the building (Bernstein, Reference Bernstein1982; Suggs et al., Reference Suggs, Stephens and Kivett1986).
Housing staff
Housing staff usually consisted of a building manager (e.g., Bernstein, Reference Bernstein1982; Heumann, Reference Heumann1988; Robbins et al., Reference Robbins, Rye, German, Tlasek-Wolfson, Penrod and Rabins2000) and maintenance staff (Heumann, Reference Heumann1988). Although these staff were typically hired for their skills in managing the physical and fiscal property, they frequently engaged in tenant-support activities (Heumann, Reference Heumann1988), despite no formal training to fulfill this role (Lucio & McFadden, Reference Lucio and McFadden2017; Suggs et al., Reference Suggs, Stephens and Kivett1986). Most housing managers reported that they had limited knowledge of which older tenants were experiencing difficulties managing their units and/or health (Heumann, Reference Heumann1988) and expressed a need for more training in identifying at-risk tenants and connecting them to services (Sheehan & Wisensale, Reference Sheehan and Wisensale1991).
Some housing providers created tenant-facing roles, such as “Tenant Resource Coordinators” (Blandford, Chappell, & Marshall, Reference Blandford, Chappell and Marshall1989), “Resident Activity Directors” (Lucio & McFadden, Reference Lucio and McFadden2017), and “Resident Services Coordinators” (Blumberg, Jones, & Nesbitt, Reference Blumberg, Jones and Nesbitt2010; Sheehan, Reference Sheehan1999) who had prior experience working with older adults and/or formal training in gerontology (Schulman, Reference Schulman1996). Tenant-facing staff had a variety of roles: they supported recreation programs (Noonan et al., Reference Noonan, Hartman, Briggs and Biederman2017) and tenant-led events (Lucio & McFadden, Reference Lucio and McFadden2017), provided information to older tenants (Blandford et al., Reference Blandford, Chappell and Marshall1989; Sheehan, Reference Sheehan1999), helped coordinate on-site services (Schulman, Reference Schulman1996), identified at-risk tenants and linked them to services (Schulman, Reference Schulman1996; Sheehan, Reference Sheehan1999), and provided training for other building staff on how to identify older adults who needed additional support (Blumberg et al., Reference Blumberg, Jones and Nesbitt2010).
From the tenant perspective, tenant support staff were key sources of companionship and provided a sense of security (Schulman, Reference Schulman1996; Sheehan, Reference Sheehan1999); they also helped foster more positive relationships between tenants (Blandford et al., Reference Blandford, Chappell and Marshall1989) and created a community-like environment where older tenants were empowered to have a stronger voice in the management of the building (Lucio & McFadden, Reference Lucio and McFadden2017).
Access to services
Although many social housing buildings for older adults were surrounded by local amenities (Smith, Sylvestre, & Ramsay, Reference Smith, Sylvestre and Ramsay2002) and health and social service agencies, including primary care centres, libraries, seniors’ centres, and family and support services (Park et al., Reference Park, Cho and Chen2019), most buildings provided some support services on site (e.g., Bingham & Kirkpatrick, Reference Bingham and Kirkpatrick1975; Suggs et al., Reference Suggs, Stephens and Kivett1986). Most of these services were provided in partnership with community agencies (e.g., Bernstein, Reference Bernstein1982; Suggs et al., Reference Suggs, Stephens and Kivett1986) and included medical and nursing services (e.g., Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019; Noonan et al., Reference Noonan, Hartman, Briggs and Biederman2017), social work (e.g., Gusmano, Rodwin, & Weisz, Reference Gusmano, Rodwin and Weisz2018), and psychiatric and mental health services (Robbins et al., Reference Robbins, Rye, German, Tlasek-Wolfson, Penrod and Rabins2000; Yaggy et al., Reference Yaggy, Michener, Yaggy, Champagne, Silberberg and Lyn2006). Community supports were also available (Chi et al., Reference Chi, Yuan and Meng2013; Suggs et al., Reference Suggs, Stephens and Kivett1986), including home care (Blandford et al., Reference Blandford, Chappell and Marshall1989), transportation (Bernstein, Reference Bernstein1982; Schulman, Reference Schulman1996), meal preparation (Bernstein, Reference Bernstein1982; Blandford et al., Reference Blandford, Chappell and Marshall1989; Schulman, Reference Schulman1996), and housekeeping (Blandford et al., Reference Blandford, Chappell and Marshall1989; Lawton & Yaffe, Reference Lawton and Yaffe1980). More recent research, however, suggested that access to homemaking and meal preparation was limited (Cotrell & Carder, Reference Cotrell and Carder2010).
The co-location of support services in social housing buildings was found to have several benefits for older tenants. It reduced unnecessary 911 calls (Agarwal, Angeles et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2018; Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019), lowered hospital use (Blandford et al., Reference Blandford, Chappell and Marshall1989; Gusmano et al., Reference Gusmano, Rodwin and Weisz2018), and shifted health care funding from ambulance and ED care to pharmacy and home-health visits (Yaggy et al., Reference Yaggy, Michener, Yaggy, Champagne, Silberberg and Lyn2006). Accessing on-site services also improved independence and safety (Soderlind, Reference Soderlind1989), promoted better physical health outcomes (Agarwal, Angeles, et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2018; Diwan, Chang, & Bajpai, Reference Diwan, Chang and Bajpai2018), and improved energy levels, mood, and mental well-being while reducing psychiatric symptoms (Lo et al., Reference Lo, Conboy, Rukhadze, Georgetti, Gagnon and Manor2018; Rabins et al., Reference Rabins, Black, Roca, German, McGuire and Robbins2000).
Although the integration of health and support services on site had positive outcomes for older tenants, the provision of these services was often uncoordinated and unplanned (e.g., Schulman, Reference Schulman1996), and there were difficulties liaising with multiple agencies due to conflicting work hours and vacation schedules, and differences in agency-specific reporting requirements (Yaggy et al., Reference Yaggy, Michener, Yaggy, Champagne, Silberberg and Lyn2006). In some cases, tenant associations helped coordinate agencies on site (Bingham & Kirkpatrick, Reference Bingham and Kirkpatrick1975; Robbins et al., Reference Robbins, Rye, German, Tlasek-Wolfson, Penrod and Rabins2000), but another study found that inactive or dysfunctional tenant groups positioned themselves as gatekeepers to prevent certain programs from coming into the building (Yoo, Butler, Elias, & Goodman, Reference Yoo, Butler, Elias and Goodman2009).
Tenant governance
Many buildings had tenant associations (e.g., Bingham & Kirkpatrick, Reference Bingham and Kirkpatrick1975; Robison et al., Reference Robison, Schensul, Coman, Diefenbach, Radda and Gaztambide2009; Yoo et al., Reference Yoo, Butler, Elias and Goodman2009) that conducted fundraising for building programs (Jacobs, Reference Jacobs1969) and advocated for tenant issues (Bingham & Kirkpatrick, Reference Bingham and Kirkpatrick1975; Jacobs, Reference Jacobs1969; Robison et al., Reference Robison, Schensul, Coman, Diefenbach, Radda and Gaztambide2009). Some of the tenants’ priorities included improvements to the built environment, increased access to exercise and food programs, better promotion of building programs to non-participants, improvements for the safety of nearby cross-walks, and creation of more outdoor transportation options (Yoo et al., Reference Yoo, Butler, Elias and Goodman2009).
Safety and security
Although only 11 studies examined issues of community safety and security, those that did reported that older tenants often felt unsafe in their buildings (Bazargan, Reference Bazargan1994; Normoyle, Reference Normoyle1987) and indicated that crime, including personal assaults and thefts, was a major problem (e.g., Lawton & Yaffe, Reference Lawton and Yaffe1980; Normoyle, Reference Normoyle1987; Parton et al., Reference Parton, Greene, Flatley, Viswanathan, Wilensky and Berman2012). This was particularly true when tenants reported that a high number of new tenants with significant mental health and addiction issues moved into the building, which resulted in higher rates of antisocial behaviours (Morris, Reference Morris2015). As a result, one-half to two-thirds of older tenants reported frequently avoiding leaving their unit (Bazargan, Reference Bazargan1994; Lawton & Yaffe, Reference Lawton and Yaffe1980), especially after dark (Morris, Reference Morris2015). Safety concerns and fear of crime reduced housing and neighbourhood satisfaction (Lawton & Yaffe, Reference Lawton and Yaffe1980), and was associated with lower morale (Smith & Sylvestre, Reference Smith and Sylvestre2008) and higher levels of depression among older tenants (Gonyea, Curley, Melekis, & Lee, Reference Gonyea, Curley, Melekis and Lee2018; Smith & Sylvestre, Reference Smith and Sylvestre2008).
Discussion
A growing number of older adults lack access to affordable housing. Older renters are particularly vulnerable, as over half of low-income older renters in North America spend more than 30 per cent of their income on housing costs (Federation of Canadian Municipalities, 2015; Joint Center for Housing Studies, 2019). Social housing programs, where rents are geared to income or supplemented with housing subsidies, are critical for helping low-income older adults access affordable housing. This scoping review examined the characteristics of older adults who live in social housing, identified factors that impact their housing stability, and explored strategies used by social housing providers to tackle these risks.
This review identified an abundance of research on social housing for older adults that spanned over five decades, with surges in publications in the 1980s and again in the 2010s, coinciding with unprecedented increases in the proportion of the population over age 65 (Hobbs & Damon, Reference Hobbs and Damon1996; Vincent & Velkoff, Reference Vincent and Velkoff2010). While some housing topics have been consistently present across decades of literature (e.g., socio-demographic and health characteristics of older tenants and access to on-site services), others have emerged (e.g., functional status, cognition) and fallen off (e.g., safety, housing policies, unit condition) over time (see Supplemental Table 4). Key lessons emerging from the findings of this review are summarized in Table 1.
Table 1. Overview of key findings
This scoping review revealed that decades of research show there is a high level of vulnerability among older adults in social housing; many face chronic physical and mental health challenges, high rates of disability, loneliness, and low levels of social support, increasing their risks of hospital admissions and nursing home placements. As declines in physical functioning were one of the main reasons that older tenants moved out of their units, co-locating health and community support services on site is a key mechanism for promoting aging in place.
Provision of on-site health and support services was found to improve a variety of health outcomes for older tenants (e.g., Agarwal et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2019; Agarwal, Angeles, et al., Reference Agarwal, Angeles, Pirrie, McLeod, Marzanek and Parascandalo2018; Diwan et al., Reference Diwan, Chang and Bajpai2018; Gusmano et al., Reference Gusmano, Rodwin and Weisz2018); however, this review highlighted that social housing providers were not usually the direct suppliers of on-site health and support services, which points to the importance of implementing strategies that foster successful collaboration between housing providers and service agencies (Redfoot & Kochera, Reference Redfoot and Kochera2004; Sheehan, Reference Sheehan1996). Studies included in this review (e.g., Yaggy et al., Reference Yaggy, Michener, Yaggy, Champagne, Silberberg and Lyn2006) and others (e.g., Canadian Urban Institute, 2020; Ontario Non-Profit Housing Association, 2015), however, highlight difficulties co-locating support services in public housing buildings due to interagency conflict with other health partners working on site and difficulties sharing confidential information across sectors. For instance, in most jurisdictions, social housing providers are not custodians of health information. Furthermore, privacy legislation requires that tenants give consent before any relevant health or housing data are shared with partners. The lack of infrastructure for promoting the sharing of confidential information further complicates this process (Canadian Urban Institute, 2020). Therefore, more research is needed to understand the barriers that health and support service agencies face collaborating with social housing providers to offer on-site services, and strategies that can be implemented to overcome those barriers, including what opportunities social housing landlords have to make this collaboration more effective.
The benefits of integrating health and support services also highlight the need for a joint strategy across provincial/state-level departments in health and housing to fund support services in social housing contexts. This macro-level integrated care (Kodner & Spreeuwenberg, Reference Kodner and Spreeuwenberg2002) is essential for creating a system that ensures older tenants can access the support services that they need when they need them. For instance, the Ontario Non-Profit Housing Association (2015, 2016b) called for a joint provincial strategy between the Ministry of Health and the Ministry of Municipal Affairs and Housing to make support services in social housing part of the core provincial budget. The need for macro-level integration is further reinforced by Canada’s National Housing Strategy (Government of Canada, 2017), which has dedicated funds to support partnerships between housing providers and support services to ensure that low-income older adults are able to age in place.
In addition to adequate funding for supports in social housing, there is a need to better understand the role and obligations of social housing landlords in identifying vulnerable tenants, connecting them to services, and supporting transitions to alternative housing (e.g., assisted living, long-term care). Most of the reviewed literature examining these types of housing policies were conducted in the 1980s and tended to focus on eligibility (e.g., Bernstein, Reference Bernstein1982; Heumann, Reference Heumann1988; Sheehan, Reference Sheehan1986a; Suggs et al., Reference Suggs, Stephens and Kivett1986), with limited emphasis on how landlords handle situations where a tenant is no longer suitable for independent living or how often this occurs (i.e., aging out of place). Of the limited and outdated research that is available, findings suggested that housing managers rarely enforced independent-living clauses due to difficulties identifying which tenants are vulnerable and in need of supports (Heumann, Reference Heumann1988; Sheehan & Wisensale, Reference Sheehan and Wisensale1991). This difficulty is likely exacerbated by challenges that housing agencies and service providers face sharing confidential tenant information across sectors (Canadian Urban Institute, 2020; Ontario Non-Profit Housing Association, 2015), notwithstanding the fact that older tenants may not want their landlord to have access to their health information. The Canadian Urban Institute (2020), a not-for-profit organization that studies national and international urban issues, suggested that plain-language consent forms and trusting relationships between tenants and housing staff are key for encouraging tenants to voluntarily agree to share personal housing and health information with relevant partners. The importance of tenant support staff was echoed in the literature reviewed here, which found that resident services coordinators and other similar positions play an important role in identifying vulnerable tenants, making linkages to services, and monitoring needs (e.g., Schulman, Reference Schulman1996). These staff also had the added benefit of fostering a sense of community where tenants were able to have input into the types of programs and services that they wanted to see in their building (Lucio & McFadden, Reference Lucio and McFadden2017).
Many tenant-support positions, however, are funded through federal or state/provincial legislation that provides guidelines on qualifications and responsibilities, and thus may not be consistent across social housing programs or available in all jurisdictions (Sheehan & Guzzardo, Reference Sheehan and Guzzardo2008). For instance, the environmental scan by the Canadian Urban Institute (2020) found that not all social housing providers supporting older adults have tenant support staff, and those that do have varied roles and responsibilities. As social housing landlords seek to implement policies and strategies to help older tenants age in place (e.g., see Locke et al., Reference Locke, Lam, Henry and Brown2011), it is essential to understand both the types of support they require (Bigonnesse & Chaudhury, Reference Bigonnesse and Chaudhury2019) and mechanisms needed to foster partnerships with service providers to facilitate these supports and ensure a soft landing in alternative housing for situations where tenants require more advanced care.
Offering accessible units with modern amenities is another way that social housing landlords can help older tenants remain in their home for as long as possible (Bigonnesse & Chaudhury, Reference Bigonnesse and Chaudhury2019; Joint Center for Housing Studies, 2020; Ontario Non-Profit Housing Association, 2016b). While several reviewed studies examined different aspects of unit condition, most were conducted in the 1970s and 1980s when social housing buildings and amenities were relatively new and tenants had just moved in. The oldest social housing buildings are now between 35 and 70 years old (Canada Mortgage and Housing Corporation, 2018a; Housing Services Corporation, 2014), and governments are increasingly investing in affordable housing redevelopment (for instance, see Canada’s National Housing Strategy [Government of Canada, 2017]). However, there has been no recent attempt to examine how the built environment of social housing has been adapted (e.g., with home modifications, retrofits) to foster independence. In fact, only two studies in this review examined accessibility (Fox et al., Reference Fox, Kenny, Day, O’Connell, Finnerty and Timmons2017; McCunn & Gifford, Reference McCunn and Gifford2014), finding that older tenants felt their unit needed many urgent upgrades (Fox et al., Reference Fox, Kenny, Day, O’Connell, Finnerty and Timmons2017) and were concerned about the ability of their unit to meet their needs as they aged due to the fact that their units were not accessible (McCunn & Gifford, Reference McCunn and Gifford2014). Other work published by the Joint Center for Housing Studies (2020) found that only 40 per cent of subsidized units met most of the requirements for “accessible livability” and that many had issues with the bathroom and kitchen and were not wheelchair accessible. Taken together, these findings suggest there is a strong need for policy efforts to take stock of necessary unit upgrades and modernizations, and provide additional funding for modifications and enhancements to ensure the built environment meets changing needs as tenants age in place.
While this review identified some of the key reasons that older tenants were evicted (due to declines in their mental health) or voluntarily left their units (due to their reduced ability to carry out daily activities), this research is dated (Bernstein, Reference Bernstein1982) and thus may not reflect current experiences. This research also does not consider other factors that impact housing stability and retention, such as safety issues, rental arrears, and poor unit condition. For example, the research on safety concerns among older tenants in social housing has tended to focus on whether tenants feel safe in their building (e.g., Parton et al., Reference Parton, Greene, Flatley, Viswanathan, Wilensky and Berman2012) and how feelings of safety impact mental health (e.g., Gonyea, Curley, Melekis, & Lee, Reference Gonyea, Curley, Melekis and Lee2018; Smith & Sylvestre, Reference Smith and Sylvestre2008). Research has yet to explore perceptions of safety among service providers working on site, and how feelings of unsafety may impact tenants’ access to services.
Older tenants may also face challenges completing their annual rent reviews to maintain access to their housing subsidy, ultimately leading to eviction due to the accumulation of rental arrears (Office of the Commissioner for Housing Equity, 2019). Although these difficulties may be linked to the complexity of the rent review paperwork, they are compounded by other issues, such as poor mental health, low literacy levels, money mismanagement and poor financial skills, and cognitive impairment (Office of the Commissioner of Housing Equity, 2019). Social housing providers and community support service agencies need to work together to address these vulnerabilities and create opportunities for financial empowerment to prevent evictions due to arrears. For instance, Toronto Community Housing Corporation (the largest social housing landlord in Canada) refers all older tenants with rental arrears to a housing equity office that uses a case management approach to address the underlying issues contributing to the arrears and broker repayment agreements, an approach that was successful at keeping 376 older tenants from being evicted (Office of the Commissioner of Housing Equity, 2019).
Declining physical and mental health may also make it difficult for many older tenants to keep their units clean and in good condition. While existing literature shows that some homemaking services are provided in social housing, level of service is not enough to meet growing needs (Cotrell & Carder, Reference Cotrell and Carder2010). Furthermore, research has not examined how access (or lack of access) to these supports directly impacts housing outcomes. For example, pest infestations, which are common in many social housing buildings, may be particularly challenging for older tenants to manage if they lack the physical or mental capacity to adequately prepare their unit for treatment and/or do not have access to appropriate formal or informal supports to help them bag their belongings. Community-based participatory approaches are needed to foster collaborations between housing providers and community support service agencies to identify strategies to support unit condition and evaluate their success.
Methodological Considerations
Scoping reviews differ from systematic reviews in that they are used to map characteristics or concepts and to identify gaps in the literature, rather than appraise and synthesize evidence for a particular practice (Munn et al., Reference Munn, Peters, Stern, Tufaranu, McArthur and Aromataris2018). Given that the body of literature reviewed here has not previously been comprehensively reviewed, and our interest in mapping characteristics of older tenants and social housing service models, a scoping review was most appropriate (Munn et al., Reference Munn, Peters, Stern, Tufaranu, McArthur and Aromataris2018). Findings from this scoping review may serve as a precursor to targeted systematic reviews that critically appraise the quality of evidence related to health service interventions integrated within social housing contexts to improve physical, mental, or social health outcomes for older tenants.
There are several limitations that should be considered when interpreting the findings from this review. First, given the vast multidisciplinary body of literature on older adults living in social housing that spans several decades, it is possible that our search missed eligible studies. Our review was not able to include studies published in languages other than English and examined those studies focused exclusively on social housing models in urban (as opposed to rural) contexts. Future research should consider social housing models for low-income older adults in rural communities, as housing options may be more limited in these settings, and health and support services may not be as readily available or accessible (Canada Mortgage and Housing Corporation, 2020). Therefore, rural communities may require different strategies to help low-income older adults age in place.
Second, our review did not examine the extensive body of grey literature that is available on this topic. For instance, some of the most recent research in the area of older adults and social housing is commissioned by state and/or federal governments or carried out by leading research centres or policy institutes, such as the Wellesley Institute, the Canadian Urban Institute, the Ontario Non-Profit Housing Association, and the Harvard Joint Center for Housing Studies. While it was not feasible to capture this growing field of grey literature in the current review, this remains a gap that should be addressed in future research.
Third, this review focused on exclusively older adults living independently in rent-subsidized independent living apartments; however, there are several other types of housing available for low-income older adults, such as sheltered, supportive, or assisted housing that future research could explore. This is particularly important for those interested in examining the integration of health and support services within subsidized housing contexts. For instance, a recently published international environmental scan of 35 low-income housing models for older adults with integrated health services (Canadian Urban Institute, 2020) found that, while rents were at or below market levels, older tenants often had to pay additional service fees to access on-site supports. One of the reviewed models included a social housing program from Winnipeg, Manitoba, where rents were geared to income (30% of gross annual household income), but the service package that included meals, housekeeping, and on-site activities was an additional $700 per month. Future research is needed to examine how supportive or assisted living programs are provided to the low-income older population, including understanding how these programs are funded and ways to increase their availability and accessibility.
Fourth, the social housing services examined in this review reflect a multitude of government-funded housing assistance programs, all with different funding and policy regulations. While it was beyond the scope of this review to examine underlying federal, provincial/state, and local housing policies, future work should consider exploring the impact of various housing policies on the type and quality of housing resources that are available to low-income older adults.
Conclusion
Social housing programs provide affordable housing options for low-income older adults. However, this review points to a high level of vulnerability among older adult tenants living in social housing, many of whom face multiple chronic physical, mental, and social health challenges that may put their housing at risk and negatively impact their ability to age in place with dignity and comfort. Our findings highlight the importance of co-locating support services in social housing buildings to help tenants access primary care and community support services, such as homemaking and meal preparation. Dedicated tenant-support staff play an integral role in identifying vulnerable older tenants who require additional supports and link them to appropriate community services. There is an acute need for more research on tenancy issues impacting older tenants (e.g., unit condition/pest control, safety, rental management) to identify additional opportunities for social housing landlords to help older tenants age in place.
