Story highlights Women working in the White House make $20,995 less on average than their male colleagues

As of 2015, the federal government gender pay gap was 11 percent

(CNN) Women working in the White House earn an average salary of 80 cents for every dollar paid to their male colleagues, a CNN analysis found.

That's a gender pay gap wider than the national average of 82 cents on the dollar, according to the Labor Department.

The average salary among men working in the White House was nearly $104,000, according to an analysis of the White House's annual report to Congress , which was released Friday. For women, it was about $83,000. That's $21,000 less on average.

The disparity is primarily due to more women filling lower-ranking jobs. Half the men working at the White House make $95,000 or more annually, while half the women $70,100 or less.

The top salary for permanent employees at the White House is $179,700. Among the 22 employees making that, only six are women.
