A new research approach to estimating the size and composition of undomiciled urban populations is presented, and its utility is illustrated through a description of the literal homeless of Chicago. The homeless in the Chicago sample are unaffiliated persons living in extreme poverty, with high levels of physical and mental disability. Homelessness is interpreted as a manifestation of extreme poverty among persons without families in housing markets with declining stocks of inexpensive dwelling units suitable for single persons.<\/jats:p>","DOI":"10.1126\/science.2950592","type":"journal-article","created":{"date-parts":[[2006,10,5]],"date-time":"2006-10-05T20:28:58Z","timestamp":1160080138000},"page":"1336-1341","source":"Crossref","is-referenced-by-count":196,"title":["The Urban Homeless: Estimating Composition and Size"],"prefix":"10.1126","volume":"235","author":[{"given":"Peter H.","family":"Rossi","sequence":"first","affiliation":[{"name":"Social and Demographic Research Institute of the University of Massachusetts, Amherst, MA 01003."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James D.","family":"Wright","sequence":"additional","affiliation":[{"name":"Social and Demographic Research Institute of the University of Massachusetts, Amherst, MA 01003."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gene A.","family":"Fisher","sequence":"additional","affiliation":[{"name":"Social and Demographic Research Institute of the University of Massachusetts, Amherst, MA 01003."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgianna","family":"Willis","sequence":"additional","affiliation":[{"name":"Social and Demographic Research Institute of the University of Massachusetts, Amherst, MA 01003."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_2_1_1_1","unstructured":"Helping the Homeess: A Resource Guide (1984)."},{"key":"e_1_2_1_2_1","unstructured":"Homelessness: A Complex Problem and the Federal Response (1985)."},{"key":"e_1_2_1_3_1","unstructured":"Persons in Institution and Other Group Quarters (1984)."},{"key":"e_1_2_1_4_1","unstructured":"Reader's Guide to Periodical Literature (1983)."},{"key":"e_1_2_1_5_1","unstructured":"A Report to the Secretary on the Homeless and Emergency Shelters (1984)."},{"key":"e_1_2_1_6_1","unstructured":"SRO's: An Endagered Species.
