The first place to look for this sort of information in the US is the Statistical Abstract of the United States [which is, sadly, scheduled to be a victim of the US budget cuts], where table 228 turns out to be "Mean earnings by highest degree earned', broken down by age, race, sex. For raw data for the UK I think you want the British Household Panel Survey. Access to the raw data or online table generation requires registration at the UK Data Archive. Someone may well have done the analysis already, though -- they have a bibliography of published papers. -thomas -- Thomas Lumley Professor of Biostatistics University of Auckland ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
