Infidelity Rates by Country 2023

Infidelity refers to someone having sex outside of his or her marriage or civil union without the permission of the other partner. Relationships can vary widely across the world, and there are some marriages in which people might allow each other to have sex with other people outside of the marriage. On the other hand, infidelity is also one of the most common reasons why both married and unmarried relationships come to an end. Therefore, it is worth exploring which countries have higher rates of infidelity than others, and the impact this might have on those around them.

How Many People Cheat on Their Significant Other in the United States?

There are surveys that have been conducted on infidelity in the United States. Approximately half of people in married relationships cheat at least one time during the course of the marriage. Close to three-quarters of men and more than two-thirds of women admit that they would sleep with someone else if it was guaranteed that they would never get caught. In addition, the majority of affairs start with close friends or co-workers. It is unusual for a one-night stand to be the cause of infidelity in a marriage. In addition, once an affair begins, it lasts an average of two years. Finally, if the affair is discovered, close to 2/3 of marriages will end immediately because of the affair.
