The Bureau of Labor Statistics says Oregon ranked eighth in the nation in women's to men's earning ratios.
Oregon women had median weekly earnings of $756 compared to $901 for men.
Matt Insco with the U.S. Bureau explains some of the variables.
"Overall, the ratio has been trending up from when he started tracking in 1997 -- in both the U.S. and Oregon. Year to year there may be slight changes, but overall the gap has been narrowing over the years."
The states with the highest wages for women were located along the eastern seaboard.
The differences among the states is in part due to the differences in the occupations and industries found in the states.
