The growth in the number of disabled adults is complicated and not fully understood. The reforms of the early 1980s and the outreach efforts in the 1980s also resulted in increases in the SSI program. With the strong economy of the late 1990s, a modest decline in SSI program participation was noted.

The reasons for this recent increase are complex and are not fully understood.
