RESEARCH DATABASE.

The Missing Persons Research Hub Research Database features research that meets the below criteria.

 

Research must be:

  • Published in a peer-reviewed journal;

  • Published from 2000 onwards;

  • Provides clarity and logic of how information in the article was generated;

  • Offers significant contribution;

  • Conforming and ethical;

  • Focuses on the Canadian context; and

  • Concentrates exclusively on topics related to missing persons.

For other research that does not meet these criteria, please see 'Resources' for more information.

Note that this database is updated annually.

Priority Directions for Missing Persons Research: Advancing Evidence, Practice, and Equity

This list highlights priority areas for future research on missing persons, drawn from current gaps in scholarship, practice, and policy. It is not exhaustive, but rather intended as a living guide to stimulate inquiry, support research development, and encourage contributions that advance evidence-informed responses to missing persons. As the field continues to evolve, so too will these priorities.

1. Structural Inequality, Vulnerability, and Risk

  • How does socioeconomic status shape both the likelihood of going missing and the resources mobilized in response (e.g., family capacity, search intensity, media attention)?

  • In dementia-related missing cases, how does access to financial and caregiving resources affect caregiver stress, response timeliness, and outcomes?

  • How do intersecting vulnerabilities (e.g., homelessness, mental health, substance use, colonial legacies) shape both risk of disappearance and case outcomes?

  • To what extent do marginalized community networks (e.g., sex workers, street-involved populations, informal care networks) function as protective systems versus sites of heightened risk in the absence of formal support?

  • How do environmental factors, including geography, seasonality, and climate, shape survival outcomes in missing cases involving vulnerable populations?
     

2. Police Practices, Decision-Making, and Institutional Processes

  • How do police services operationalize and apply risk classification (e.g., “high priority”) in missing persons cases, and how consistent are these determinations across jurisdictions?

  • What organizational, cultural, and resource-based factors influence investigative responses, including timelines, search deployment, and case persistence?

  • How do frontline officers, call-takers, and investigators interpret and respond to reports from third parties (e.g., social workers, housing providers, hospital staff)?

  • What are the lived experiences of professionals (e.g., social workers, outreach workers) when reporting clients missing, and how do these interactions shape case trajectories?

  • What constitutes “effective” missing persons investigations in practice, and how can this be operationalized into evidence-based guidelines?
     

3. Data, Classification, and the Limits of Police Records

  • To what extent are missing persons misclassified or misidentified (e.g., incorrect identity factors, such as gender or race/ethnicity) within police records, and what are (if any) the downstream implications for investigation and recovery?

  • How do reporting thresholds, classification practices, and documentation systems shape what becomes visible in missing persons data (i.e., extending the concept of police data ceilings)?

  • What is the nature and quality of administrative paperwork and data systems in jurisdictions with dedicated missing persons legislation, and how do these structures influence case management?

  • How do inconsistencies across records systems (police, healthcare, social services) affect information sharing and case resolution?
     

4. Technology, Media, and Information Ecosystems

  • How does social media exposure (e.g., viral posts, demographic characteristics of cases) influence recovery outcomes, search mobilization, and public engagement?

  • What are the risks and benefits of emerging technologies (e.g., drones, facial recognition, AI-assisted search tools) in locating missing persons, particularly in cold or long-term cases?

  • How do digital inequalities (access to technology, online visibility) shape whose cases receive attention and resources?

  • What role do media narratives and public engagement play in shaping investigative priorities and perceptions of “deservingness”?
     

5. Institutional Interfaces and Interagency Collaboration

  • What are the motivations and systemic conditions underlying missing incidents originating from institutional settings (e.g., hospitals, group homes, care facilities)?

  • How do interagency dynamics between police, healthcare, and social services influence response effectiveness and continuity of care?

  • To what extent does collaboration act as both a support and a stressor across agencies involved in missing persons cases?

  • What models of interagency coordination produce the most effective outcomes for prevention, response, and recovery?
     

6. Law, Policy, and Governance

  • How effective are existing provincial and territorial missing persons legislation frameworks in improving investigative capacity and outcomes?

  • What legislative or policy reforms could better support timely information sharing, risk assessment, and cross-jurisdictional coordination?

  • How do legal frameworks intersect with issues of privacy, autonomy, and consent in cases involving adults who go missing?

  • What gaps exist between policy intent and frontline implementation in missing persons response?
     

7. Identity, Representation, and Equity

  • How do racism, colonialism, and queerphobia shape both public understanding and institutional responses to missing persons, particularly in cases involving Missing and Murdered Indigenous Women and Girls?

  • How are gender identity and sexual orientation accounted for or erased in reporting, investigation, and public communication?

  • How do disparities in attention (media, police, public) reproduce inequities in outcomes across different groups of missing persons?
