The authors find that services for homeless persons have increased across the United States. However, they also clearly demonstrate that we have not solved—or even diminished—the homelessness problem. Although we have the cure, we have directed our resources toward treating the symptoms. The authors point out that because cross-sectional studies often fail to capture people who are temporarily homeless, they falsely inflate the proportion of chronically homeless people within the homeless population. The authors suggest that policy design should differentiate crisis situations from chronic homelessness. Sometimes a "quick fix," such as emergency financial assistance, really is the answer for a particular individual or family. This approach is more rational than providing services only after the individual or family becomes homeless. For many homeless people, the answer is simply affordable housing. For the chronically homeless, the evidence argues for a "continuum of care" built around affordable housing. Finally, prevention is essential to eradicate the risk of homelessness.
