The gender pay gap is the difference in the average hourly earnings of men and women. The gender pay gap is expressed as a percentage of men’s earnings.

The gender pay gap in the United States is 18.1%. This means that, on average, women earn 81.9% of what men earn.

There are many factors that contribute to the gender pay gap. Some of these factors include:

• The prevalence of women in low-paying occupations
• The prevalence of women in part-time work
• Occupational segregation (the segregation of men and women into different occupations)
• The motherhood penalty (the fact that mothers are often penalized in the workforce)
• The wage gap between women and men with the same level of education

The gender pay gap is a complex issue with many factors contributing to it. In order to close the gender pay gap, we need to address all of these factors.
