Chronic homelessness is a highly complex social problem of national importance. The problem has elicited a variety of societal and public policy responses over the years, concomitant with fluctuations in the economy and changes in the demographics of and attitudes toward poor and disenfranchised citizens. In recent decades, federal agencies, nonprofit organizations, and the philanthropic community have worked hard to develop and implement programs to solve the challenges of homelessness, and progress has been made. However, much more remains to be done. Importantly, the results of various efforts, and especially the efforts to reduce homelessness among veterans in recent years, have shown that the problem of homelessness can be successfully addressed. Although a number of programs have been developed to meet the needs of persons experiencing homelessness, this report focuses on one particular type of intervention: permanent supportive housing (PSH). Permanent Supportive Housing focuses on the impact of PSH on health care outcomes and its cost-effectiveness. The report also addresses policy and program barriers that affect the ability to bring the PSH and other housing models to scale to address housing and health care needs.

Widely heralded as a “masterful” (Washington Post) and “essential” (Slate) history of the modern American metropolis, Richard Rothstein’s The Color of Law offers “the most forceful argument ever published on how federal, state, and local governments gave rise to and reinforced neighborhood segregation” (William Julius Wilson). Exploding the myth of de facto segregation arising from private prejudice or the unintended consequences of economic forces, Rothstein describes how the American government systematically imposed residential segregation: with undisguised racial zoning; public housing that purposefully segregated previously mixed communities; subsidies for builders to create whites-only suburbs; tax exemptions for institutions that enforced segregation; and support for violent resistance to African Americans in white neighborhoods. A groundbreaking, “virtually indispensable” study that has already transformed our understanding of twentieth-century urban history (Chicago Daily Observer), The Color of Law forces us to face the obligation to remedy our unconstitutional past.

The report describes potential applications of geographic information systems (GIS) and spatial analysis by HUD's Office of Policy Development and Research for understanding housing needs, addressing broader issues of urban poverty and community development, and improving access to information and services by the many users of HUD's data. It offers a vision of HUD as an important player in providing urban data to federal initiatives towards a spatial data infrastructure for the nation.
