The closest number I saw was December 2001 - November 2002, and it was 2.2 percent. That meant that average incomes did not keep up with inflation, and, using the link you provided, non-governmental salaries went up about .8 percent - or about 1.4 percent LESS than the rate of inflation.
Thanks for the link, BTW. It's helped my case a lot more than it's helped yours.
