not complete. In describing the extent of impoverishment in the United States, these nonmonetary indices would provide important added information.

Second, in this volume we have not explored, analytically or descriptively, the material circumstances of those who are poor: for example, what household goods they have or how they allocate their resources among categories of consumption. Also, we have not asked about the consequences of economic poverty in terms of other dimensions of impoverishment. We encourage research that asks how economic poverty is linked to families' day-to-day lives—for example, to family violence, homelessness or frequent moves to different households, safety of their neighborhoods, or access to friends, services, and jobs. Similarly, the consequences of economic poverty for access to health care and social services, for an individual's self-esteem, mental and physical health, school achievement, prospects for employment, marriage, and parenting all deserve much more research attention. Also, we have not considered in this volume how the consequences of economic poverty differ by an individual's age or other characteristics. These other, less easily quantified indexes of well-being that may or may not be associated with economic poverty are also deserving of study in order to have a fuller understanding of the lives of the poor and a more complete documentation of the consequences of living in poverty.

Consider, in this regard, the life experiences of children who are poor. Evidence suggests that children living in poor families under the current measure score lower on cognitive, language, and achievement tests and exhibit higher rates of grade failure, of placement in special education, and of dropping out of high school (see Baydar, Brooks-Gunn, and Furstenberg, 1993; Brooks-Gunn, Guo, and Furstenberg, 1993; Fitzgerald, Lester, and Zuckerman, 1995; Haveman, Wolfe, and Spaulding, 1991; Huston, 1991; Huston, McLoyd, and Garcia Coll, 1994; Ramey et al., 1992). Children's physical health indicators, such as low birth weight, failure to thrive, and chronic illnesses, also have been shown to be related to measured poverty (Adler et al., 1994; Brooks-Gunn, 1990; Egbuonu and Starfield, 1982; Eisen et al., 1980; Klerman, 1991; McCormick et al., 1991; Parker, Greer, and Zuckerman, 1988; Stein et al., 1987). Moderate to severe behavior problems in children are also linked statistically to economic poverty (see, e.g., Rutter, 1989).

At the same time, other social and demographic characteristics of families are associated with negative child and adolescent outcomes, including parents' education, age, and occupation and household structure (i.e., two- or one-parent households). Controlling for such characteristics in statistical models of child outcomes generally diminishes but does not eliminate the association between economic poverty and these outcomes. Such findings underscore the importance of considering other dimensions of poor children's lives that contribute to the probability of decrements in all realms of development.
