Social Statistics and an American Urban Underclass: Improving the Knowledge Base for Social Policy in the 1990s
本文指出社会统计在描述美国城市底层阶级问题上发挥了重要作用，但现有统计不足以理解其形成机制，需改进以更好服务于1990年代的社会政策。
Abstract Social statistics have played a large role in describing the nature of the problem of an emerging urban underclass in the United States and in placing these issues on the public agenda and before the research community. Extant social statistics, however, are inadequate to the task of understanding the processes and mechanisms that create, maintain, or overcome the conditions and consequences of the urban underclass. Without theoretically informed social statistics of organizations and institutions and of geographic and contextual detail, social statistics will be unable to inform public policy in the 1990s.
