Puebla has claimed the top spot in Mexico for the highest number of active users on Ashley Madison, the extramarital dating platform, marking a notable shift in the country’s relationship dynamics. This ranking, released in 2026, places Puebla ahead of major cities like Monterrey, Guadalajara, and Tijuana.

This is the second consecutive year Puebla appears on the list, but it’s the first time it leads nationally. It’s important to note that these figures reflect only activity within the app and do not represent an official study on infidelity or relationship behaviors across the population.

Here’s the full top nine cities with the most Ashley Madison users in Mexico:
– Puebla — leading nationally with the highest active user count
– Monterrey — strong metropolitan presence
– Guadalajara — significant user concentration seeking encounters
– Zapopan — consistently high app activity
– Aguascalientes — steady growth in registrations
– Tijuana — openness to new relational dynamics
– Mexicali — rising user numbers in northern Mexico
– Chihuahua — notable activity in the north
– Hermosillo — rounds out the list with prominent engagement

Interestingly, Mexico City, despite being the country’s largest urban center, does not appear in this ranking.

Ashley Madison’s analysis points to several socio-economic and cultural factors behind these trends:
– Economic independence and population density in large cities provide anonymity, nightlife, and discretion opportunities.
– Generational shifts toward more flexible relationship models challenge traditional monogamy.
– Tourism and “escape” environments create spikes in activity as residents and visitors seek to break routine.

Supporting this context, data from Mexico’s National Institute of Statistics and Geography (INEGI) shows that 33% of marriages ended in divorce in 2024, with an average marital duration of just 12 years.

While the Ashley Madison ranking highlights where users are most active, it does not measure the actual frequency of infidelity in the general population. Still, it offers a revealing glimpse into evolving social patterns in Mexican cities like Puebla, where new forms of connection and personal freedom are increasingly visible.

For migrants and young adults navigating relationships in Mexico or abroad, understanding these shifts can provide valuable insight into the changing landscape of intimacy and trust in contemporary society.
