Wages for technology professionals fell 6.21% year over year by the end of the third quarter, according to the Yoh index of technology wages.

Tech wages were up 1.86% year over year at the start of the quarter, but fell over time. Now they are at the lowest level since the beginning of 2006.

"It appears that the demand for technology workers continues to ebb," said President and CEO Bill Yoh. "We believe we'll continue to see softening in certain sectors as the state of the economy leads companies to tighten budgets and delay projects. Although it's too early to predict exactly when this wage downturn may end, we expect it will continue through the remainder of 2008, but improvement in the financial markets may create some stability in early 2009."

However, there are still some bright spots with tech wages in healthcare, telecom and aviation holding steady, according to Yoh.

The index is based on data compiled by Yoh's 75 U.S. field offices.
