From the AMCAS Help Section regarding the disadvantaged status:
State and Federal Assistance Programs: These programs are specifically defined as "Means-Tested Programs" under which the individual, family, or household income and assets must be below specified thresholds. The sponsoring agencies then provide cash and non-cash assistance to eligible individuals, families, or households. Such programs include welfare benefit programs (federal, state, and local); Aid to Families with Dependent Children (AFDC or ADC); unemployment compensation; General Assistance (GA); food stamps; Supplemental Security Income (SSI); Medicaid; housing assistance; or other federal, state, or local financial assistance programs.
