This report discusses the share of the federal budget devoted to older Americans, which is growing. The federal government currently spends more than one-third of its budget on benefits and programs for older Americans. For people age 65 and over, estimated FY2007 spending for Social Security, Medicare, and Medicaid alone is $833 billion. Spending for retired federal employees and military personnel and for veterans is also significant, and smaller programs add to the total as well. Tax expenditures might also be taken into account to obtain a more complete budget picture.
