Affair statistics do not follow a straight line. In a 2022 survey of 2,000 married Americans, 21% of men and 14% of women reported at least one extramarital affair during their current marriage. The figures look similar across groups, but the motives differ, with emotional dissatisfaction named as a main driver in a 2021 Archives of Sexual Behavior study.
Key Takeaways
- In the 2023 American Community Survey analysis, men aged 18-29 were 2.5 times more likely to report affairs than women in the same age group
- A 2022 meta-analysis in Journal of Family Psychology found 40% of discovered affairs lead to divorce within 2 years
- A 2021 study in Archives of Sexual Behavior found 57% of affairs start due to emotional dissatisfaction in marriage
- In a 2022 survey of 2,000 married Americans, 21% of men and 14% of women reported having had at least one extramarital affair during their current marriage
- In a 2023 U.S. divorce court analysis, 55% of filings cite infidelity as primary cause
Overall, affair rates remain relatively low, but they significantly impact relationships and trust for those involved.

Motivational Factors Interpretation
The statistics paint a clear, if motley, picture: infidelity often blooms not from a single villainous desire, but from a weary, complex garden of unmet needs, emotional cracks, fleeting opportunity, and the very human, sometimes misguided, search for connection, validation, or simply a spark in the mundane.
