2004 Trustees Report
The following tables present the plot points for Figure IV.B1--OASI and DI Trust Fund income rates and cost rates (as a percentage of taxable payroll) on a calendar year basis for the historical period (1990-2003) and the long-range projection period (2004-2080). In the projection period, cost rates are shown under all three sets of assumptions. Only alternative II income rates are shown because of the small difference among the three alternatives.
