Although homelessness has been recognized as a serious and growing urban social problem, scientifically acceptable methods for estimating the composition and size of the homeless population have been lacking. 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.
尽管无家可归已被公认为一个严重且日益加剧的城市社会问题，但一直缺乏科学上可接受的方法来估算无家可归者群体的构成和规模。本文提出了一种估算城市无住所人口规模和构成的新研究方法，并通过对芝加哥的真正无家可归者的描述来说明其效用。芝加哥样本中的无家可归者是生活在极端贫困中、身体和精神残疾程度很高的无亲属关系者。无家可归被解释为在适合单身人士居住的廉价住宅存量不断减少的住房市场中，无家庭者极端贫困的一种表现。
