CBO's 2010 Long-Term Projections for Social Security, October 2010: "Social Security is the federal government's largest single program. About 54 million people currently receive Social Security benefits. About 69 percent are retired workers, their spouses, and children and another 12 percent are survivors of deceased workers; all of those beneficiaries receive payments through Old-Age and Survivors Insurance (OASI). The other 19 percent are disabled workers or their spouses and children; they receive Disability Insurance (DI) benefits. Social Security's outlays in fiscal year 2010 totaled $706 billion, one-fifth of the federal budget; OASI payments accounted for 82 percent of those outlays and DI payments made up about 18 percent."
