The Social Security Trustees Report showed a largely similar outlook compared to the report last year, though it was slightly worse. Trust fund exhaustion dates were similar other than the date for the separate Old-Age and Survivors' Insurance (OASI) fund, which was brought forward one year to 2034. In addition, the 75-year actuarial shortfall increased slightly from 2.72 percent of taxable payroll to 2.88 percent, largely the result of changes in economic assumptions and shifting the 75-year period over one year.
As a percent of payroll, the change is entirely concentrated on the spending side, but this appears to be more a factor of payroll shrinking than nominal dollar spending increasing. Social Security revenue is the same at 13.9 percent of payroll over the 75-year period, while spending is 0.2 percentage points higher than last year at 16.8 percent.
Looking back further, as we noted in our analysis of the report, the outlook for the program has deteriorated in each of the last four reports. Below, we show the assets in the trust fund over time as projected in the 2010, 2012, and 2014 Trustees reports.
While the change in Social Security projections this year is relatively small, there are some interesting sources for those changes, some of which may have implications for future changes in Trustees forecasts.
