What GAO FoundThis document is an E-supplement to GAO-12-497. This e-supplement provides information on state trends in applications, medical allowances, and benefit Supplemental Security Income (SSI) receipts for children with mental impairments from 2000 to 2011. It contains two interactive maps, which can be accessed using the links below. The first map presents state data on SSI applications and allowances for children with mental impairments. Data represented as “applications” reflect SSI benefit claims where a disability determination services (DDS) examiner made an initial disability determination decision. Some applications may have been submitted prior to the year when a determination was made. In addition, some applications could have more than one determination if the claim is selected for a quality review or if the disability claim is updated during the same year. Data on allowances and allowance rates refers to initial level allowances, not final allowances, which include appeals decisions. The second map presents state data on benefit receipts for children with mental impairments, as well as for children with the primary impairments most frequently medically allowed for SSI benefits—attention deficit hyperactivity disorder (ADHD), speech and language delay, and autistic disorder and other pervasive development disorders (autism). (Children with attention deficit disorder are also included in the ADHD category.) To account for variations in state size, applications (determinations) and receipts data are presented as a share of the state child population for each year. To navigate between years and impairments, click on the hyperlinked tabs across the top of maps. Roll your mouse over a state to view state data for the selected year and impairment.
