Apropos of some discussion of salaries on Twitter and in the comments, I dug around until I found what I wanted, which is the salary comparison of both academic and industrial chemists by education, experience and quartiles/quintiles. This data is thanks to the 2005 ChemCensus, performed by the ACS Committee on Economic and Professional Affairs. (I anxiously await the 2010 ChemCensus results.) The tables were taken from the individual academic and industrial reports.
It would be terribly interesting to see what the top 1% of academic and industrial chemists make. Are there income inequality trends among chemists? I don't see why they would be immune to broader trends in the United States.
