    IGH Community of Impact: Housing First in International Contexts

    International Housing First Research and Programs:

    How do communities work upstream to prevent homelessness? How does data and evidence inform targeted prevention strategies?

    In our recent Community of Impact Webinar, we sought to investigate these questions by featuring homeless prevention experts and strategies from around the globe. Homelessness prevention works to address the causes of homelessness before it occurs. Traditionally, homeless services and systems focus on serving people after they become homeless. Growing evidence indicates that prevention strategies help communities reduce the number of people entering the homeless system. People who experience homelessness are not homeless due to some innate characteristic that they possess; homelessness results after a failure of multiple systems. It is important to understand the gaps that exist in systems in order to disrupt the inflow of people becoming homeless and drive change. 

    A comprehensive approach to homelessness prevention operates at different levels, addressing both direct causes of homelessness and working further ‘upstream’ to address issues contributing to the loss of housing. Certain prevention strategies involve targeting resources toward those who are at imminent risk of homelessness by providing services such as rental assistance or landlord-tenant mediation to those at risk of eviction. Other preventative approaches seek to identify risk factors – such as school absenteeism or contact with social services – well in advance and intervene prior to a point of crisis. Communities may also seek to address underlying structural issues such as housing stability, for example, by prioritizing affordable housing development or access to housing subsidies to combat homelessness. 

    This IGH Community of Impact Webinar featured four experts on homelessness prevention, each bringing their own unique perspectives to the topic. 

    • Abe Oudshoorn, Ph.D., Assistant Professor at Western University in London, Ontario and the Managing Editor of the International Journal on Homelessness. 
    • Lynette Barnes, Manager of All Chicago’s Emergency Financial Assistance Program
    • Katie Shomacker and Melissa Matthews, Team Leaders for the Geelong Project

    Research and Programs That Were Featured in the Webinar:

    • Evolving an evidence‐based model for homelessness prevention

      The full paper can be accessed here. 


      While some progress has been made in addressing chronic homelessness through supportive models, a comprehensive solution for housing loss must include prevention. The purpose of this article is twofold: to conduct a review of the literature on the domains of the Framework for Homelessness Prevention; and to use literature on the concept of quaternary prevention, preventing the harms of service provision, to theorise an additional domain. The Framework for Homelessness Prevention draws upon theory from public health exploring primary, secondary and tertiary prevention, and also integrates primordial prevention. This leads to a typology of homelessness prevention that incorporates the following five domains: (a) Structural prevention; (b) Systems prevention; (c) Early intervention; (d) Eviction prevention; and (e) Housing stability. By systematically reviewing the literature we build out the evidence‐base supporting these domains. The team used research databases, internet searches and retrospective reference list reviews to identify high‐quality journal articles on prevention, which were then sorted by level of prevention. Through this process, we evolved our thinking on the Framework in considering that quaternary prevention was not initially included. Therefore, we explored the literature related to quaternary prevention in the context of homelessness and offer a sixth domain for the Framework: Empowerment. Ultimately, a comprehensive Framework for Homelessness Prevention will support communities and governments to more effectively prevent homelessness through upstream approaches.
    • Does emergency financial assistance reduce crime?

      Read the full paper here.


      Does emergency financial assistance reduce criminal behavior among those experiencing negative shocks? To address this question, we exploit quasi-random variation in the allocation of temporary financial assistance to eligible individuals and families that have experienced an economic shock. Chicago’s Homelessness Prevention Call Center (HPCC) connects such families and individuals with assistance, but the availability of funding varies unpredictably. Consequently, we can determine the impact of temporary assistance on crime by comparing outcomes for those who call when funds are available to those who call when no funds are available. Linking this call center information to arrest records from the Chicago Police Department, we find some evidence that total arrests fall between 1 and 2 years after the call. For violent crime, police arrest those for whom funds were available 51% less often than those who were eligible but for whom no funds were available. Single individuals drive this decrease. The decline in crime appears to be related, in part, to greater housing stability—being referred to assistance significantly decreases arrests for homelessness-related, outdoor crimes such as trespassing. However, we also find that financial assistance leads to an increase in property crime arrests. This increase is evident for family heads, but not single individuals; the increase is mostly due to shoplifting; and the timing of this increase suggests that financial assistance enables some families to take on financial obligations that they are subsequently unable to meet. Overall, the change in the mix of crime induced by financial assistance generates considerable social benefits due to the greater social cost of violence

    • The Geelong Project – Interim Report

      The Geelong Project – Interim Report has revealed it is producing unprecedented results in preventing ‘at-risk’ young students from becoming homeless, disengaging in their education and leaving school early. The first three years of The Geelong Project led by Barwon Child, Youth & Family, has seen a 40% reduction in the number of homeless young students in Geelong, a 20% reduction in early school leaving and a 50% reduction in the level of school disengagement* by at risk students in the pilot schools. This has been as a result of the introduction of a collaborative early intervention approach.

    Prevention Literature Reviews and Typologies:

    • Homelessness Prevention: A Review of the Literature

      Resource can be accessed here. 

      Shinn and Cohen provide an overview of homelessness prevention strategies and review the current state of knowledge on the subject. Factors that predict homelessness are discussed in addition to the evidence-based interventions that have thus far proven effective at preventing homelessness such as permanent deep rental housing subsidies, eviction prevention services, and community-based services targeted at assisting those at risk of becoming homeless. Also addressed are current gaps in the research that would be helpful to address, such as improving efficiency and effectiveness of prevention programs as well as better understanding who experiences homelessness and how their needs can be best addressed.

    • Preventing youth homelessness - An international review of evidence

      The resource can be accessed here. 

      In the context of a global shift towards prevention, this international review identifies evidence-based interventions, promising practices, youth-identified prevention priorities, and intersecting policy elements contributing to the prevention of youth homelessness.

      The report draws upon a careful assessment of this evidence base to develop a set of recommendations to effectively divert young people from experiences of homelessness.

    • A New Direction: A Framework for Homelessness Prevention

      The resource and explanatory videos can be accessed here.

      The aim of the framework is to begin a conversation in Canada on what prevention looks like, and what it will take to shift toward homelessness prevention. Using international examples, the framework operationalizes the policies and practices necessary to successfully prevent homelessness and highlights who is responsible.

      In Turning Off the Tap: A Typology for Homelessness Prevention, Dej, Gaetz, and Schwan seek to establish a definition and typology for homelessness prevention in order to clarify the thinking around homelessness prevention. The authors define homelessness prevention as actions taken to reduce the likelihood of a person experiencing homelessness, focusing on a housing-led approach that also includes providing supports and services to ensure that housing is secure once established. The authors argue for a five dimensional typology of homelessness prevention – structural prevention, systems prevention, early intervention, evictions prevention, and housing stability. The proposed typology for homelessness prevention is intended to draw attention to the multi-sectoral strategies needed to comprehensively address homelessness and facilitate a move away from reliance on crisis-based responses to homelessness.

    • Predicting and Preventing Homelessness in Los Angeles

      Read the full paper here. 

      The California Policy Lab and the University of Chicago Poverty Lab have used County data on multi-system service use to predict homelessness among single adults receiving mainstream County services. By identifying people at high risk of first-time homelessness or returns to homelessness and understanding risk factors associated with future homelessness, the County can more effectively target its homelessness prevention efforts to ensure limited resources are going to those most likely to benefit from them.

    • Homelessness prevention in Newcastle: Examining the role of the ‘local state’ in the context of austerity and welfare reforms

      The full paper can be accessed here. 

      This report examines how Newcastle’s ‘local state’ (the city council and relevant partners) are preventing homelessness in the context of local government funding cuts and welfare reforms, and how the approaches might be improved. The mixed-methods study has quantitatively compared Newcastle with other core cities using key administrative and survey-based data sources, and employed qualitative interviews and focus groups with expert local stakeholders, frontline workers, and residents with experience of homelessness or homelessness risk.

    IGH launched our Community of Impact (CoI) to connect leaders and practitioners to a collaborative and dynamic global network of knowledge of what works in ending homelessness. COVID-19 has represented an enormous challenge as the pandemic has had a disproportionate impact on vulnerable populations especially people experiencing homelessness.

    In our first Community of Impact Webinar, we were honored to have three speakers who discussed how data and coordinated responses allowed their communities to adopt quickly and effectively to COVID-19  in order to protect and house people experiencing homelessness. The three speakers were:

    • Jeremy Swain, UK Advisor for the United Kingdom Ministry of Housing, Communities and Local Government
    • Dr. Surashree Shome, Senior Manager at Azim Premji Philanthropic Initiatives
    • Molly Seeley, Special Projects Manager for the Institute of Global Homelessness

    The video of the webinar can be found here. From Great Britain to Bengaluru, India, the speakers’ presentations had common themes in their presentations:

    • Strong leadership with multi-sector coordination including the formation of taskforces resulted in improved communication, collaborative action, and led to better outcomes, and 
    • disaggregated data allowed leaders to better understand the scope of the impact and design new initiatives that are more inclusive and better targeted to specific populations.
