Mérida, Oaxaca, San Miguel de Allende: 2025 SESNSP Crime Data Compared for Tourists
Mérida, Oaxaca, San Miguel de Allende: 2025 SESNSP Crime Data Compared for Tourists
Three cities dominate every "best of Mexico" travel list: Mérida, Oaxaca de Juárez, and San Miguel de Allende. Travel magazines rank them annually. American retirees relocate to all three. Instagram feeds overflow with their cobblestone streets and rooftop bars. The conventional wisdom is that they're all "safe" — equally so, the kind of vague reassurance that doesn't survive contact with actual data.
This guide is built on a different premise: these three cities sit at three different risk levels on the SafeTravel index, and the gap between them is wide enough to change how you plan a trip. We're going to walk through what the 2025 SESNSP (Secretariado Ejecutivo del Sistema Nacional de Seguridad Pública) crime data actually shows — month by month, crime type by crime type — for each of the three cities. Then we'll translate those numbers into what they mean for a tourist standing in the centro histórico with a backpack.
This is the data case for choosing between Mexico's three most popular colonial cities in 2026.

Quick Reference: The Three Cities at a Glance
| Factor | Mérida | Oaxaca de Juárez | San Miguel de Allende |
|--------|--------|------------------|------------------------|
| State | Yucatán | Oaxaca | Guanajuato |
| Population | 995,129 | 270,955 | 176,322 |
| US State Dept Advisory (state level) | Level 1 — Exercise Normal Precautions | Level 2 — Exercise Increased Caution | Level 3 — Reconsider Travel (state) |
| SafeTravel Risk Score (0–10, lower = safer) | 1.05 | 2.05 | 2.90 |
| SafeTravel Risk Level | Low | Moderate | Elevated |
| Tourist Destination (official) | Yes | Yes | Yes |
| Best known for | Yucatán cuisine, cenotes, haciendas, Paseo de Montejo | Zapotec ruins, mezcal, artisan markets, Guelaguetza | Art schools, expat community, rooftop bars, Spanish-colonial architecture |
| Tourist season peak | Dec–Mar (dry, cool) | Oct (Guelaguetza) + Dec–Feb | Oct–May (mild highland weather) |
The headline: All three are tourist destinations on official state tourism promotion. All three are covered in the same travel publications. And yet the SafeTravel index — built on 1.5 million SESNSP records — rates them across a nearly 3x risk spread. The reason is in the crime types and the geography, and the next three sections break it down.

The 2025 SESNSP Crime Data: Side by Side
The table below shows the most recent 12 months of crime data reported to SESNSP for each city. The numbers are raw incident counts, not rates — SESNSP reports are aggregated monthly at the municipal level. We'll translate these into per-capita figures in the next section.
Total Reported Crimes (Trailing 12 Months)
| Metric | Mérida | Oaxaca | San Miguel de Allende |
|--------|--------|--------|------------------------|
| Total incidents (12-mo) | 905 | 1,169 | 1,708 |
| Per 100,000 residents (12-mo) | ~91 | ~431 | ~969 |
| Risk-score relative position | Lowest | Middle | Highest |
The per-capita numbers are the most important. San Miguel de Allende — a city of 176,000 — reports roughly 10.6x more crime per resident than Mérida, a city of nearly 1 million. Population is not the explanation. The data is.
Top Crime Types (Trailing 12 Months)
Mérida:
- Daño a la propiedad (property damage): 239
- Lesiones (assault/injury): 153
- Amenazas (threats): 114
- Robo (theft): 64
- Fraude (fraud): 55
- Violencia familiar (domestic violence): 52
- Robo (theft): 330
- Lesiones (assault/injury): 138
- Amenazas (threats): 112
- Violencia familiar (domestic violence): 108
- Fraude (fraud): 66
- Robo (theft): 425
- Otros delitos del Fuero Común (other state-jurisdiction crimes): 235
- Lesiones (assault/injury): 170
- Daño a la propiedad (property damage): 166
- Violencia familiar (domestic violence): 155
- Amenazas (threats): 138
- Domestic settings (violencia familiar)
- Interpersonal disputes unrelated to tourism
- Alcohol-fueled incidents in nightlife zones
- You want the lowest possible per-capita crime exposure in a Mexican city
- You value state-level advisory consistency (the whole state of Yucatán is Level 1)
- You want access to cenotes, haciendas, and the Ruta Puuc
- You're traveling with family members who are nervous about Mexico travel
- You want the cheapest of the three for a comparable experience
- You're prioritizing culture, food, and Zapotec history over safety margins
- You're willing to accept moderate (Level 2) advisory state context
- You want access to mezcal country, artisan markets, and the Pacific coast day-trips
- You're an experienced Mexico traveler comfortable with the centro histórico pattern
- You want the most distinctive cuisine in Mexico
- You have a specific reason to be there (art school, expat community, wedding, real estate)
- You accept elevated (Level 3) state-level advisory and plan around it
- You understand the per-capita crime data and have decided the city's amenities outweigh it
- You're staying within the centro histórico and reducing night-time movement outside of it
- You're visiting for a short, contained stay rather than extended travel
- Per-capita normalization — San Miguel's small population makes raw counts misleading without the per-capita adjustment
- Cross-validation with Numbeo — user-reported perception data from thousands of residents
- Time-of-day and zone breakdowns — risk varies enormously between the centro histórico and the peripheral neighborhoods
- State-level contextualization — accounting for the Guanajuato, Oaxaca, and Yucatán state contexts in which each city sits
- Tourist-specific risk weighting — separating crimes that affect tourists from crimes that don't (domestic violence, for instance, has near-zero tourist exposure in all three cities)
Oaxaca de Juárez:
San Miguel de Allende:
The pattern is consistent across all three: property crime and interpersonal disputes dominate. What changes is the volume. San Miguel de Allende's theft count (425) is 6.6x Mérida's (64), and the gap is not explained by tourism volume — San Miguel's tourism footprint is a fraction of Mérida's.
Monthly Trend (Latest Quarter)
| Month | Mérida | Oaxaca | San Miguel de Allende |
|-------|--------|--------|------------------------|
| January 2026 | 269 | 366 | 560 |
| February 2026 | 307 | 405 | 558 |
| March 2026 | 329 | 398 | 590 |
The trend lines are stable. None of the three cities is showing a sudden surge or drop. The relative ranking has held for at least the most recent year of data. Plan accordingly.

Why the Numbers Look the Way They Do
Raw counts don't explain themselves. Here's the structural picture for each city.
Mérida: Yucatán's Geography Is the Story
Yucatán state is physically separate from Mexico's main drug-trafficking corridors. The peninsula has one major highway in and one major highway out. There's no mountain pass, no border, no major port. That geography creates a structural advantage that the SESNSP data reflects: very low rates of the violent crimes that dominate headlines elsewhere in Mexico.
For tourists, the practical translation is straightforward. Walking in Mérida's centro histórico at 11pm is, in safety terms, more like walking in a mid-sized European city than walking in central Mexico City. The main risks are pickpocketing in crowded markets (San Benito, Lucas de Gálvez) and rental-car break-ins at cenote parking lots — both preventable with normal precautions. The Yucatán state US State Department advisory is Level 1, the lowest category, shared with destinations like Canada and most of Western Europe.
Oaxaca: A Capital City With Capital-City Crime Patterns
Oaxaca de Juárez is a real working capital. It's the state capital of Oaxaca, the seat of state government, home to a major university, and a hub for the surrounding Zapotec and Mixtec regions. The 270,955 population is a fraction of Mérida's, but the per-capita crime rate is roughly 4.7x higher.
The dominant crime type is robo (theft) — the broad SESNSP category that includes street theft, vehicle break-ins, and commercial robbery. Tourist-targeted street theft in the centro histórico is uncommon but not rare. Most incidents involve locals, and the safer neighborhoods for tourists (Reforma, Jalatlaco, Xoxocotlán outskirts) are clearly distinct from the higher-incident peripheral neighborhoods.
The state-level US State Department advisory is Level 2 — Exercise Increased Caution, the same as Jalisco (Puerto Vallarta) and Nayarit (Sayulita). The advisory reflects state-wide data that includes rural areas in the Mixteca and Sierra Sur regions — a tourist in central Oaxaca is not exposed to those conditions. Still, the data justifies a more cautious posture than Mérida.
San Miguel de Allende: A Tourist Town in a Tough State
This is the most counter-intuitive entry in the comparison. San Miguel de Allende is frequently described as "Mexico's safest city" in expat forums and travel publications. The SESNSP data does not support that framing.
San Miguel de Allende sits in Guanajuato, one of Mexico's most violent states. The state-level US State Department advisory is Level 3 — Reconsider Travel, the same category as Sinaloa, Michoacán, and Tamaulipas. San Miguel's city-level numbers are better than Guanajuato's capital (the city of Guanajuato itself) or industrial Irapuato, but they are still substantially worse than either Mérida or Oaxaca.
The theft count of 425 in a 12-month period is the data point that should change how tourists plan. Most incidents are non-violent, but a non-trivial share occurs in and around the centro histórico, particularly at night. Thefts from parked cars, snatch-and-grab on the Ancha de San Antonio, and pickpocketing in the Mercado de Artesanías are recurring reports. The risk is not extreme — the SafeTravel index still rates it as a viable tourist destination — but it is materially higher than the other two cities, and the state-level advisory reflects that.

The Tourist Translation: What These Numbers Mean For Your Trip
SESNSP data is municipal-level and includes all incidents, not just tourist-facing ones. Translating it into practical advice:
Theft Risk (the variable that actually changes your trip)
| Scenario | Mérida | Oaxaca | San Miguel de Allende |
|----------|--------|--------|------------------------|
| Walking in centro at night | Low risk | Low-moderate risk | Moderate risk |
| Pickpocketing in markets | Low risk | Moderate risk | Moderate risk |
| Car break-in (tourist rental) | Low risk | Moderate risk | Higher risk |
| Snatch-theft of phone/wallet | Very low | Low | Moderate |
| Day trip to surrounding pueblos | Very low | Variable | Higher in rural Guanajuato |
Theft is the dominant crime type across all three cities. For tourists, this means: don't carry your passport, leave jewelry in the hotel safe, use a crossbody bag in crowded markets, and treat rental cars as visible storage (which they are not).
Violent Crime (Low Across All Three, But Not Zero)
Direct violent victimization of tourists is rare in all three cities. The data shows violent crime is overwhelmingly concentrated in:
For a tourist exercising standard urban awareness, the odds of violent victimization are very low in all three cities. The reason to choose one over another is theft risk and the cumulative weight of the surrounding state context — not fear of violence per se.
The Day-Trip Footprint Matters
Mérida's day-trip options (cenotes, Uxmal, Izamal, Valladolid) sit in Yucatán state, which is uniformly low-risk. The day-trip risk profile is consistent with the city itself.
Oaxaca's day-trip options (Mitla, Hierve el Agua, Teotitlán del Valle) sit in Oaxaca state and carry variable risk. Some pueblos are exceptionally safe; others (parts of the Sierra Sur, certain Pacific-coast towns) are not. Stick to the established day-trip circuit.
San Miguel de Allende's day-trip options (Dolores Hidalgo, Guanajuato city, Querétaro) sit in a state with Level 3 advisory. The day-trip to Guanajuato city itself is fine, but the broader state's risk profile follows you.

Quick FAQ
Is San Miguel de Allende actually dangerous?
Not "dangerous" in the absolute sense — violent victimization of tourists is rare. But the data shows it is substantially higher-risk than Mérida or Oaxaca. The expat-community reputation doesn't match the SESNSP data.
Is Oaxaca safe for tourists?
Moderate-risk, not low-risk. Standard urban precautions (watch your phone, secure your rental car, stay alert in crowded markets) cover nearly all incidents.
Why is Mérida so much safer than the other two?
Geography. The Yucatán peninsula is physically separate from Mexico's main trafficking corridors. That structural advantage is reflected in every category of crime data.
Should I trust the SafeTravel index or the US State Department advisory?
Both. The SafeTravel index uses the same underlying SESNSP data, normalized and weighted for tourist exposure. The State Department advisory provides state-level context, which is useful but not city-specific.
What's the single biggest mistake tourists make in all three cities?
Leaving valuables visible in parked rental cars. Rental car break-ins account for a disproportionate share of tourist theft incidents in all three cities — and they are 100% preventable.

The Bottom Line
If you rank these three cities purely on SESNSP-derived per-capita crime data, the order is Mérida → Oaxaca → San Miguel de Allende, with roughly a 3x risk spread between the safest and the highest-risk of the three. That ordering doesn't change the fact that all three are viable tourist destinations, and all three are routinely visited by hundreds of thousands of American travelers each year. But the gap between them is real, and the data is consistent. Plan accordingly.
