¹Michigan data include both Ribicoff and child welfare children; however, Michigan officials estimated that the vast majority of the children reported in this group qualified under the Ribicoff provisions. Thus, the combined Michigan data are used for comparison with data on Ribicoff children in California and New York.

²Less than 1 percent.
