No single indicator can capture the effectiveness of a social program. Therefore, SSA has developed a number of outcomes for the OASI, DI and SSI programs. Each outcome contains multiple data indicators that reflect the different bases and objectives of each program.These indicators measure how well the Agency's programs provide for the economic security of its beneficiary populations.he outcome indicators in this section show both the extent to which individuals have other sources of the income they need to ensure economic security and the comparative role that OASDI and other sources play in economic security.
