Nationally, when exploring the uncontrolled gender pay gap --which compares the median salary of every working woman to the median salary of every men --men make more than woman in every U.S. state. Alabama has the biggest uncontrolled gap, with women making 27 percent less than men. The state with the smallest uncontrolled gender pay gap is Vermont. Still, even in the famously liberal Green Mountain State, women still make about 15 percent less than men.

The controlled gender pay gap data paints a slightly more equitable picture when women have the same job title and we control for other wage influencers. In Connecticut, the controlled gender pay gap is $1.005, meaning women make 0.5 cents more than comparable men. In Vermont, Oregon, New Mexico, Rhode Island, Alaska, and the District of Columbia, the controlled difference in pay incredibly close to zero.

Louisiana and Alabama are the two states with the largest controlled gender pay gaps. Women in Louisiana make 94.4 cents for every dollar comparable men earn. In Alabama women do marginally better, making 94.9 cents for every dollar earned by men.
