Homeless Veterans


Research & Methodology



The Research and Methodology Core conducts and supports research into the causes and contributing factors of Veteran homelessness; assesses the effectiveness of programs; and serves as a resource center for all research activities carried out by the Department of Veterans Affairs and by other Federal and non-Federal entities with respect to Veteran homelessness. The Center is focused on four areas of inquiry:

  • Predictive analytics — using large administrative data sets (i.e. “big data”) to develop predictive models that will be able to pre-emptively identify individual Veterans before an adverse event occurs so that a preventative intervention can be provided. 
  • Population modeling — providing a greater understanding of the needs and trends among subpopulations of homeless Veterans, including women, rural, OEF/OIF/OND, aged, and those with specific clinical conditions and needs.
  • Systems efficiencies and effectiveness — looking specifically at how well different VA programs and medical centers interact and coordinate efforts to achieve optimal results in housing and keeping housed homeless Veterans.
  • Program evaluation and implementation research — ensuring that new models of care are being evaluated with substantial rigor to see that best practices are being identified and replicated with high fidelity.
