Average private sector wages in the United States rose 3.0 percent in 2011, which was more than the 1.2 percent average increase for federal government workers. This was the second year in a row that average private pay rose faster than average federal pay, but that comes after many years of an escalating federal pay advantage.

CBO has released a study comparing the wages and benefits of private sector and federal non-military workers. The study uses statistical techniques to make comparisons with adjustments for education level, experience, and other factors.
