New research shows that companies with more diverse workforces are more likely to financially outperform less diverse peers. Specifically, companies in the top quartile for gender and ethnic diversity are 15-35% more likely to have financial returns above the national industry median. Additionally, companies in the bottom quartile for both gender and ethnic diversity are statistically less likely to achieve above-average financial returns. This suggests that diversity provides competitive advantages that can shift market share to more diverse companies over time.
