Remapping Debate has put together an interesting interactive tool you can use.  I’m showing a static image of the tool below because security precautions at wordpress.com (this blog’s host) prevent including the full scripted interactive tool.  But if you click on the image you will be taken to the Remapping Debate site and the interactive tool itself.

There you can change the year as you wish using the slider in the lower left.  The orange bars indicate the percentage of the workforce that earns that bracket of compensation.  The first bar, for example, tells us the approximately 16% of the workforce earned less than $4,999.99 in 2009.   The blue bars tell us the percentage of the total U.S. compensation earned by the workers in that bracket.
