Homelessness and the People Living in Encampments.To learn more about encampments and cities’ approaches in responding to them, Abt Associates conducted the study Exploring Homelessness Among People Living in Encampments and Associated Costs for the U.S. Department of Health and Human Services and the U.S. Department of Housing and Urban Development (HUD). After completing a literature review, the study team selected nine cities currently responding to encampments to participate in telephone interviews in early 2019. The nine cities were Chicago, Illinois; Fresno, California; Houston, Texas; Las Vegas, Nevada; Minneapolis, Minnesota; Philadelphia, Pennsylvania; Portland, Oregon; San Jose, California; and Tacoma, Washington. In the fall of 2019, the team conducted site visits to Chicago, Houston, San Jose, and Tacoma to collect cost information on expenditures explicitly related to encampments, interview implementation partners, observe encampments, and interview a small number of encampment residents.
