This report describes 15 major public programs serving low-income, non-elderly adults with disabilities. The authors conclude that the safety net for low-income adults with disabilities is more like a tangled web of conflicting goals and gaps in needed services. Opportunities for temporary cash, training, and rehabilitation support are especially limited for disabled adults with limited work histories and/or who experienced their disability outside of work. SSI, a permanent cash benefit program that could likely lead to a lifetime of program participation, is the primary option for these adults. The authors discuss promising policy options that take a more coordinated approach in serving the complex needs of adults with disabilities.
