Women who work full time, year round in the United States are paid just 80 cents for every dollar paid to their male counterparts. This gap, which amounts to a typical loss of $10,086 per year for a working woman—or $403,440 over a 40-year career—means that women have to work 15 months, until April 10, to make what men did in the previous 12-month calendar year.

Despite the fact that women have made enormous gains in educational attainment and labor force involvement in the last several decades, unequal pay remains pervasive in 97 percent of occupations, showing that no matter what their job, women are paid less than men doing the same job in nearly every sector of work.
