Research on infidelity among affluent women is limited, but studies suggest that it is a significant issue. A 2017 survey conducted by the American Community Survey (ACS) found that approximately 20% of married women in the United States reported having an affair. While there isn't specific data on affluent women, another study published in the Journal of Marriage and Family in 2018 found that women with higher incomes and education levels were more likely to engage in infidelity.
