WASHINGTON (AP) _ New numbers say the gender gap in pay among federal employees is shrinking. Women working in the federal government still earn less than their male counterparts. But the difference in average annual salary for men and women has declined from 19 cents to 11 cents on the dollar between 1998 and 2007. That's according to a draft report from the Government Accountability Office. The report says all but 7 cents of the gap can be accounted for by differences in measurable factors, such as differences in education levels and the type of jobs men and women had. The gap narrowed the more men and women shared characteristics, including the jobs held, levels of experience and education. The gap among federal employees has been steadily shrinking since 1988, when female government workers earned 28 cents on the dollar less than men.
