The purpose of this study was to determine the effects of poverty, program generosity, and health on state variations in enrollment of children and adolescents in the Supplemental Security Income (SSI) program during recent program expansions.
The relationship of state SSI rates for 1989 and 1992 to child poverty, health, and program generosity were determined by multiple regression.
The mean percentage of children enrolled grew from 0.36% (1989) to 0.75% (1992). Poverty rates accounted for 78% of the variance among states in 1989 and 53% in 1992. Other indicators accounted for little variance.
Differences in state poverty levels explained almost all variation in SSI enrollment.
本研究的目的是确定在近期项目扩张期间,贫困、项目慷慨程度和健康状况对各州儿童及青少年参与补充保障收入(SSI)项目的入学率差异的影响。
通过多元回归确定1989年和1992年各州SSI率与儿童贫困、健康状况和项目慷慨程度之间的关系。
参与项目的儿童平均百分比从1989年的0.36%增长到1992年的0.75%。贫困率在1989年占各州差异的78%,在1992年占53%。其他指标占差异的比例很小。
各州贫困水平的差异几乎解释了SSI入学率的所有差异。
