Tuesday is Equal Pay Day, a  day designed to draw attention to the unequal pay between men and women in this economy.  

There are lots of caveats and warnings about the pay gap data, but the generally accepted number is that women make about 78 cents for every buck a man earns.  The folks over at FiveThirtyEight have aggregated some state by state data, and came out with — what else in data journalism today, but a chart.

Washington, D.C. is the closest to pay parity. Women there make 90 cents to every man’s dollar.

Wyoming’s dead last: 63 cents there.
