- 20% of the gender wage gap in the OECD area remains unexplained after accounting for observable factors, per OECD work on wage gaps and discrimination
- 0.74% 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
- 90% of large employers in the U.K. with gender pay reporting obligations had to publish their Gender Pay Gap reports annually starting 2018, establishing a recurring compliance reporting requirement
- 62% of organizations reported performing compensation banding in a 2023 survey, which is a structural control used in pay equity practices

- 47% of organizations said they expanded their pay equity analytics capabilities in 2022–2023, indicating industry trend toward data-driven equal pay
- 58% of companies in a 2023 global survey reported using some form of pay data standardization (e.g., common job architecture), a trend relevant to equal pay
- 12 months is the median time horizon companies reported for completing a pay equity analysis after data collection (vendor implementation timelines)
- 2.8x more likely to identify pay inequities when using regression-based methods versus simple mean comparisons (statistical method comparison in published analysis)
- 6% median annual adjustment to address identified inequities was reported by organizations in a 2023 pay equity implementation survey

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
