The Harvard Kennedy School Government Performance Lab (GPL) Homelessness & Housing team seeks to provide actionable information that helps localities make the most of their housing resources, especially when capacity is limited. By improving data capacity and optimizing system management, we aim to empower system leaders to drive better outcomes for those experiencing homelessness.
Homelessness is a growing problem. According to the 2024 Annual Homeless Assessment Report (AHAR), approximately 770,000 people experienced homelessness on a single night, an increase of 18% from the prior year. This marks the highest increase in homelessness since the federal government began conducting an annual count in 2007.
The lack of deeply affordable housing is also growing. In 2022, only 7.2 million units rented for less than $600 per month — down from 9.3 million units in 2012. Cities and state leaders are grappling with long wait lists for housing, significant numbers of people who need behavioral health support in addition to housing support, and limited resources to meet those needs.
Significant expansions of deeply affordable housing, fully optimizing existing housing resources, and expanding access to behavioral health care has never been more important.
One of the most effective and evidence-based solutions for addressing homelessness is Permanent Supportive Housing (PSH), which combines deeply affordable housing assistance with behavioral and social health supports. This evidence-based approach has proven effective at reducing homelessness, improving behavioral health outcomes, and achieving cost-savings in other emergency systems such as jails, emergency rooms, and shelters.
To understand how Coordinated Entry Systems (CES) facilitate connections to Permanent Supportive Housing (PSH), the GPL conducted a national survey and interviewed CES leaders and PSH providers.
This report offers insights from primarily Continuums of Care across the nation, highlighting challenges and opportunities related to optimizing PSH management. We recognize the vital role of other stakeholders such as housing providers, clients, developers, and communities in addressing homelessness, and will work to incorporate their perspectives into future research and collaborative efforts.
From these conversations and the GPL’s work with jurisdictions across the country, we identified four major field opportunities:
Within each field opportunity, we present several questions to help leaders work toward actionable steps. Taken as a whole, these 10 guiding questions can help leaders take meaningful steps toward strengthening their permanent supportive housing systems.
