Equal pay is a fundamental issue affecting working families. While the number of women workers in the labor force has steadily increased, the contribution of women’s wages to family income has also grown, with women’s earnings now providing a significant portion of total household income. Although the wage gap has narrowed over the years, pay inequity remains, and there continues to be a significant portion of total household income. Although the wage gap has narrowed over the years, pay inequity remains, and there continues to be significant differences in wages paid to women, minorities, men, and non-minorities. If women were to receive wages equal to those of comparable men, working families across the United States would gain s staggering $200 billion in family income annually, with each working woman’s family gaining more that $4,000 per year. In a new joint study, the Institute for Women’s Policy research and the AFL-CIO investigate the size of the wage gap in the United States as well as in the 50 states and the District of Columbia. The study demonstrates the costs of pay inequity to both working families and individuals, and reveals some alarming figures as to how much family income is lost on account of the wage gap and unequal pay for comparable work.
