So, what is the average wage in the United States? And what will it be five, ten or fifty years from now? Today, Political Calculations(TM) is mining historical data for the purpose of modeling the current and future level of the U.S. National Average Wage Index (NAWI) so you don't have to!
Update 26 October 2010: Welcome Bing searchers! Please be aware that the tool presented below is out-of-date - we have a much newer version available for your number crunching needs!
The data being used for the formula extraction is provided by the Social Security Administration, who tracks the data from 1951 and uses it to index an individual's lifetime earnings for the rate of inflation in wages in determining their Primary Insurance Amount (PIA), or rather, the basic level of one's Social Security retirement benefit.
The following chart shows the change in the National Average Wage Index over the number of years since 1951, as well as the formula extracted using Microsoft Excel's regression analysis capability:

The formula indicates that the annualized rate of increase with continuous compounding in the NAWI index is 5.23%. The following tool allows you to select any year from 1951 to 2100 in order to estimate the value of average wages in the United States using the generated formula, assuming that the level of its future growth is similar to that of the past 54 years:
