The 82 percent wage ratio figure, the most commonly used figure to measure the gender wage gap in the United States, is often derided as misleading, a myth, or worst of all, a lie. In this post, we argue that the figure is an accurate measure of the inequality in earnings between women and men who work full-time, year-round in the labor market and reflects a number of different factors: discrimination in pay, recruitment, job assignment, and promotion; lower earnings in occupations mainly done by women; and  women’s disproportionate share of time spent on family care, including that they—rather than fathers—still tend to be the ones to take more time off work when families have children.
