aThe estimated odds ratio is the estimate of the relationship between the characteristic and p/(1-p) where p is the probability that the person is enrolled in Medicaid three months after leaving AFDC, and (1-p) is the probability a person is disenrolled from Medicaid three months after leaving AFDC.

bCompared to whites.

cCompared to adults aged 35 through 64.

dCompared to no expenditures.

*Significantly different from zero at the .10 level, two-tailed test.

**Significantly different from zero at the .05 level, two-tailed test.

***Significantly different from zero at the .01 level, two-tailed test.
