Despite passage of the Equal Pay Act of 1963, which requires that men and women in the same work place be given equal pay for equal work, the "gender gap" in pay persists. In 2014, the typical woman working full-time all year in the United States earned only 79 percent of what the typical man earned working full-time all year. Phrased differently, she earned 79 cents for every dollar that he earned. The pay gap is even greater for African-American and Latina women, with African-American women earning 64 cents and Latina women earning 56 cents for every dollar earned by a white non-Hispanic man. Decades of research shows that no matter how you evaluate the data, there remains a pay gap — even after factoring in the kind of work people do, or qualifications such as education and experience — and there is good evidence that discrimination contributes to the persistent pay disparity between men and women. In other words, pay discrimination is a real and persistent problem that continues to shortchange American women and their families.
