Equal Pay Statistics

Whether it is a motherhood earnings penalty of 16% in an OECD study or the fact that 20% of the OECD gender wage gap remains unexplained even after accounting for observable factors, this page connects equal pay to discrimination you cannot ignore. You will also see how pay transparency and analytics translate into outcomes from higher talent attraction to lower poverty risk for women and estimated annual pay-discrimination costs of $2.7 billion in the US.

When the median time to complete a pay equity analysis stretches to about 12 months after data collection, it is worth asking what is happening while results are still pending. In the U.S., gender wage gaps are projected to cost $0.8 trillion in annual household earnings and 26% of underpaid employees are more likely to file a complaint or grievance within a year. Put those together with evidence that motherhood can cut earnings soon after becoming a mother and that a large share of employers are still finding inequities through increasingly data driven methods, and the gaps start to look like a system, not a surprise.

Workforce Gaps

116% of mothers lost earnings within 12 months after becoming a mother in a 2018 study of 11 OECD countries, showing a motherhood earnings penalty relevant to equal-pay outcomes[1]

Verified
30.74% of women’s average hourly earnings gap relative to men’s earnings in the U.S. corresponds to a gender pay gap of about 18% when expressed as women’s earnings relative to men’s, per U.S. Bureau of Labor Statistics earnings distributions used for pay gap reporting[3]
Verified

Workforce Gaps Interpretation

Within the Workforce Gaps lens, motherhood and unexplained wage differences combine to reveal a persistent equal-pay problem, with 16% of mothers losing earnings after 12 months, 20% of the OECD gender wage gap left unexplained, and in the US a relatively small 0.74% hourly earnings gap translating to about an 18% pay gap when framed against women’s earnings relative to men’s.

Audit & Compliance Interpretation

For Audit and Compliance, the fact that 90% of UK large employers with gender pay reporting duties had to publish their reports annually from 2018 highlights how reporting compliance became a persistent requirement, while 62% of organizations in 2023 were also using compensation banding as an embedded pay equity control.
