According to the Institute for Women’s Policy Research:
Women are almost half of the workforce. They are the equal, if not main, breadwinner in four out of ten families. They receive more college and graduate degrees than men. Yet, on average, women continue to earn considerably less than men. In 2010, female full-time workers made only 77 cents for every dollar earned by men, a gender wage gap of 23 percent. Women, on average, earn less than men in virtually every single occupation for which there is sufficient earnings data for both men and women to calculate an earnings ratio.
You might be surprised to know which industries paid women the worst. Here’s Rex Crum from Marketwatch to lay out the statistics on the gender pay gap.
