Most women will never earn as much as men in their lifetimes.

In Wyoming, it will take 144 years for equal pay,  according to a recent report from the Institute for Women’s Policy Research that looked at  trends in women’s employment and earnings . Other states with particularly high disparities included Louisiana, North Dakota and Utah. The state with the shortest wage gap, Florida,was still 23 years. And Washington, D.C. marks the best place for women’s employment and earnings, the report found, perhaps because it is small and urban. Still, the pay imbalance won’t close until 2055.

Tuesday marks national  Equal Pay Day , an event from the National Committee on Pay Equity, a nonprofit advocacy group. The date represents how long into 2015 it would take a woman to earn what a man did in 2014.
