6. Norway – 41%
Norway’s 41% rate of female infidelity highlights how liberal attitudes toward relationships can affect marital fidelity. Scandinavian societies often embrace sexual freedom and equality, giving women the autonomy to explore personal desires. Seasonal changes, travel opportunities, and workplace dynamics can also provide occasions for extramarital affairs. While marriage remains important, Norwegian culture’s focus on personal happiness contributes to this higher-than-average infidelity rate.
