Cook County workers saw their average compensation decline by 0.3 percent in 2009 to $67,791 per job, according to statistics released Tuesday by the Bureau of Economic Analysis.

When adding the compensation of all workers, Cook County experienced a decline of 5.2 percent to 1.7 million. Cook was among the more than 2,000 counties — about two-thirds — that experienced compensation declines in 2009.

Despite a 1.2 percent increase in the average annual compensation per job to $56,962, total compensation decreased by 3.2 percent across the U.S. The decline was due to job losses.

The Great Lakes region, which includes Illinois, Indiana, Michigan, Ohio and Wisconsin, accounted for 14 percent of the nation’s total compensation. Oscoda County, in Michigan, experienced the worse decline in the region at a negative 29 percent. Workers in Lawrence County saw biggest increase at 11.2 percent.

Job losses in the durable-goods manufacturing, construction and professional and scientific and technical services industries contributed to the overall decline in compensation.
