Gender Pay Gap

The difference in average earnings between men and women — typically expressed as women earning X cents for every dollar earned by men.

The gender pay gap measures the difference in earnings between men and women across the workforce. The most commonly cited figure — women earning roughly 82–84 cents for every dollar earned by men in the U.S. — is the 'raw' or unadjusted gap, which compares median earnings across all full-time workers regardless of occupation, industry, experience, or hours. The 'adjusted' gap, which controls for these factors, is smaller but still persistent — typically 94–98 cents on the dollar — representing pay differences between men and women in the same or similar roles.

The causes of the gender pay gap are multifactorial: occupational segregation (women are concentrated in lower-paying fields), the 'motherhood penalty' (women's earnings decline after having children while men's often increase — the 'fatherhood bonus'), negotiation differences, and direct pay discrimination. The gap also compounds over time: starting salaries anchor future raises, and women who negotiate are still penalized at higher rates than men who do the same.

Pay transparency laws are the most significant policy shift in closing the gap. California, Colorado, New York, Washington, Illinois, and a growing number of states now require employers to post salary ranges in job listings — eliminating the information asymmetry that has historically disadvantaged women and minorities in negotiations. Early evidence from Colorado and California suggests transparency is narrowing starting salary gaps, particularly for women in professional roles.

Adjusted vs. Unadjusted Gap

  • Unadjusted gap: compares all men vs. all women — reflects occupational segregation and career interruptions.
  • Adjusted gap: controls for role, level, experience, and hours — measures pay for comparable work.
  • Both matter: the unadjusted gap reflects systemic inequity in which careers are valued; the adjusted gap reflects what's happening within companies.
  • The adjusted gap is what internal pay equity audits and Equal Pay Act claims typically measure.
  • The gap is larger for women of color — Black women earn roughly 67 cents, Latinas 58 cents, for every dollar earned by white men (unadjusted).

What You Can Do About It

  • Research market rates before any salary negotiation — use multiple sources (Levels.fyi, Glassdoor, Bureau of Labor Statistics) to build a data-backed range.
  • In states with salary history bans, you're not required to disclose your current pay — and employers can't use it to set your offer.
  • Use pay transparency laws to your advantage: in states that require salary ranges in job postings, use those ranges as your anchor.
  • Request a pay equity review from your manager or HR — many companies will conduct one if asked directly.
  • If you discover a significant, unexplained pay gap with a peer of the opposite sex doing the same work, you may have an Equal Pay Act claim — consult an employment attorney.

The Equal Pay Act vs. Title VII

Two separate federal laws address pay discrimination. The Equal Pay Act of 1963 specifically prohibits paying employees of different sexes differently for 'equal work' — the same job requiring the same skill, effort, and responsibility. EPA claims don't require proof of discriminatory intent; you just have to show the pay disparity exists. Title VII of the Civil Rights Act is broader — it covers all forms of sex (and race, religion, national origin) discrimination, including pay, but requires showing discriminatory intent or disparate impact. In practice, pay discrimination claims often proceed under both statutes. Unlike most employment claims, EPA claims don't require filing with the EEOC first — you can go directly to court within two years (three for willful violations).

Example

A pay equity audit at a tech company reveals that female software engineers earn 6% less than male peers after controlling for level, tenure, and performance ratings. The company issues pay adjustments, tightens its offer-setting process to start candidates within a narrow band of the midpoint regardless of prior salary history, and eliminates the practice of asking candidates their current salary — which had been anchoring offers for women who were underpaid at prior employers.
