Study Ranks Mexico Among Top Three Most Unfaithful Countries in Latin America

Mexico City, Mexico — A new study on relationship behavior in Latin America places Mexico at the center of an intense debate about fidelity and new forms of emotional connection, ranking the country third for infidelity in the region.

The research by Dive Marketing, conducted for the European platform Gleeden, reveals surprising statistics that challenge traditional monogamy structures and expose how people are reinterpreting commitment in the 21st century.

According to the findings, 67 percent of surveyed Mexicans admit to having been unfaithful at least once, though 59 percent of those report experiencing feelings of regret afterward.

Latin American Rankings

The study confirms Mexico occupies the third position among the most unfaithful countries in Latin America, ranking just below Brazil and Colombia in the volume of extramarital interactions. The complete ranking is:

• Brazil
• Colombia
• Mexico
• Argentina
• Chile

Within Mexico, Mexico City leads the list of areas with the highest activity of this type, followed closely by the State of Mexico and Nuevo León. Jalisco and Querétaro complete the top five, highlighting as entities with accelerated economic growth and vibrant social life.

Changing Attitudes

One of the study’s most provocative discoveries indicates that six out of ten Mexicans consider infidelity a “natural” human behavior. Many participants justify these actions as responses to biological or emotional needs that their primary relationship doesn’t fully satisfy.

Some even defend the idea that external encounters can “oxygenate” the formal relationship, breaking definitively with rigid romantic love schemes. Researchers associate these figures with high connectivity and the pace of life in large metropolitan areas, where social networks act as catalysts for new encounters.

The study emphasizes that despite growing acceptance of these practices in Mexico, stigma and moral dilemmas still persist in the collective consciousness.
