1 The real-wage differential is the difference between nominal wage growth and inflation. This differential is calculated as the percent change in average annual covered wages minus the percent change in the average annual CPI-W. Numbers may not add due to rounding.

2 The average annual interest rate is the average of the 12 monthly nominal interest rates for special public-debt obligations issuable to the trust funds. In practice, these rates are compounded semiannually.

3 The rates shown are unadjusted civilian unemployment rates.

4 Labor force is the total for the United States (including military personnel) and reflects the average of the monthly numbers of persons in the labor force for each year.

5 The real GDP (gross domestic product) is the market value of all final goods and services produced by labor and property located in the U.S., expressed in 1996 dollars.

6 The Consumer Price Index is the average annual value for the calendar year of the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

7 Preliminary. Wages in covered employment are considered preliminary for several years primarily due to uncertainty of estimates for amounts above the benefit and contribution base.
