2. The program trustee’s report now uses the Social Security definition without calling it a “replacement rate” (Social Security Administration, 2009b:198-199).


3. Taking the perspective of the past, however—and depending on the actual earnings history and benefit calculation—dual-earner couples may have either lowered or raised the whole-couple earnings replacement rate, compared to that for individual workers.


4. As said, like Chapter 6 and unlike the rest of the report, this appendix relies on the intermediate economic and other assumptions of the 2009 report of the Social Security Trustees, rather than Congressional Budget Office assumptions. In this way our detailed Social Security illustrations are consistent with the program’s data. A recent comparison of the two is in Congressional Budget Office (2009).


5. To estimate these three illustrative options, the rate of real wage inflation was taken at 1.1 percent annually, the long-term rate used by the Social Security trustees for the current intermediate projections.


6. For this and other options, the sum for the individual provisions may not equal the option’s total (here, 2.02 percent) because of interaction among the effects of the provisions.
