While the U.S. has made strides toward reducing the gender wage gap over the decades, new researchtoday shows just how far there is to go.

At the current rate of progress, the gender pay gap — thedifference between women's and men's earnings — won't close nationwide until 2058,according to a report from the Institute for Women's PolicyResearch.

Women in Florida might see equal pay the soonest, with the stateprojected to reach pay parity in 2038.

If you're a woman living in Wyoming, the picture is bleakest. Thegender wage gap won't close there until 2159, making it one of fivestates that won't see pay equality this century.

Here's the research institute's full list:

In 2013 women earned 78.3 cents on the dollar compared with men,up from 76.5 cents in 2012, according to the report, which citesresearch by Carmen DeNavas-Walt and Bernadette Proctor at the U.S.Census Bureau.

Currently New York is closest to gender wage parity, with womenearning 87.6 cents on the dollar. Louisiana is the worst among the50 states plus Washington, D.C., at 66.7 cents.

In the past few decades, men's earnings adjusted for inflationhave been relatively flat, while women's have grown. However, sincethe early 2000s, women's earnings also have started to stagnate,the report says.

Participation in the workforce has followed a similarpattern.

"Despite progress in many parts of the country, women’s statuson employment and earnings either worsened or stalled in nearlyhalf of the states in the last decade,” Heidi Hartmann, presidentof the research institute, said in a statement.

“When half the country is not seeing any gains in women’semployment and earnings, it is a concerning prospect for thenation’s economy as a whole.”
