Mexico tops the list by a wide margin, and it has for years. The full answer is more complicated than a single country name, because the official numbers don’t measure exactly what the headline asks.
The main source is the State Department’s public record of non-natural deaths of U.S. citizens abroad. Researchers and the CDC both use it. This article walks through what it shows, where it falls short, and which causes matter most.
What the Official Numbers Actually Count
The State Department doesn’t publish a clean table of tourist deaths. It records reported non-natural deaths of U.S. citizens abroad, which can include more than short-term travelers.[1] Expats, long-term residents and dual nationals can all appear in the file. So “tourist deaths” is shorthand, not a precise category.
There is a second limit. The CDC notes that the data exclude deaths not reported to a U.S. embassy or consulate.[2] Natural causes, such as heart attacks, are also left out. Treat any ranking as a guide to common hazards, not a measure of danger per vacation.
Mexico Leads by a Wide Margin
In the State Department file for 2020 to 2022, Mexico has the highest total, with 537 recorded non-natural deaths of U.S. citizens.[3] A separate January to June 2023 worksheet shows the same pattern. It lists 532 recorded deaths in total[1], and Mexico accounts for 172 of them.[1] That’s nearly a third of all deaths in that half-year file.[1]
The 2023 sheet shows Mexico with major counts in homicide, auto crashes, drowning, and other accidents rather than one single dominant category.[1] No one cause explains the total. The country is simply where many Americans drive, swim, party and live.
Why Mexico’s Raw Count Needs Context
Mexico is also the country Americans visit most. One summary of the data says it draws close to 39 percent of all American travelers while contributing to about one third of the total U.S. deaths abroad.[4] That’s a rough comparison, but it shows the raw count partly reflects volume.
An older comparison from 2014 and 2015 makes the point. Mexico had 228 American deaths against about 25.9 million American visitors[5]. Thailand had 35 deaths against 339,000 visitors.[5] That data is dated, but it shows how a smaller country can have a higher rate even with a lower total.
Road Crashes Are the Biggest Killer
Violence gets the headlines, but vehicles do more damage. The CDC’s 2026 Yellow Book reports that over 1,500 U.S. citizens died from non-natural causes abroad in 2019 to 2021, with motor vehicle crashes the leading cause at 26%.[2] Its figure lists 402 motor vehicle deaths, against 292 homicides.[2]
Mexico had 141 U.S. citizen road traffic deaths in that period, the highest total.[6] The Dominican Republic came second with 21.[6] Most victims were in ordinary vehicles: 62% were drivers and occupants of passenger vehicles, and 19% involved motorcycles.[2] The CDC also warns that trauma centers capable of treating serious injuries are uncommon outside urban areas.[2]
Homicide Is Concentrated in a Few Places
Homicide is the second leading cause in the CDC’s 2019 to 2021 figures. It is also geographically lopsided. More than 68 percent of all homicide deaths of U.S. citizens abroad occurred in Mexico.[7] An earlier Yellow Book edition also named the Philippines, Jamaica and Haiti among the countries with the highest numbers of homicides among U.S. travelers.[8]
Mexico’s numbers do not mean every resort is dangerous. The State Department has issued warnings about gang violence in parts of the country. It has also warned that U.S. citizens have become seriously ill or died in Mexico after using synthetic drugs or adulterated prescription pills.[9] Risk varies a lot by region, so a country-level figure hides more than it shows.
Drowning Hits Beach Destinations Hardest
Water is the other major hazard. The CDC says drowning is often the leading cause of injury death to U.S. citizens visiting countries where water recreation is a major activity.[8] In the 2020 to 2022 file, Costa Rica ranks next after Mexico with 52 cases, and drowning is the dominant category.[3] The Dominican Republic follows closely with 49.[3]
The pattern is long-running. By 2016, Costa Rica had recorded 101 American drownings since the registry began in 2002.[5] The CDC points to likely contributors: unfamiliarity with local currents, inability to swim and no lifeguards on duty.[8] Rip currents, which tourists rarely recognize, are a particular concern.
Thailand and Southeast Asia Show a Different Pattern
Thailand has smaller totals but regularly appears near the top. In the January to June 2023 sheet it recorded 14 deaths, which kept it in the top seven.[7] A 2016 analysis said that among countries with significant numbers of American visitors, Thailand had the highest rate of unnatural death.[5] That analysis predates the pandemic, so the exact ranking may have shifted.
Motorbikes are a recurring factor across the region. The CDC advises against motorcycle and motorbike travel abroad, including motorbike taxis.[10] Drug-related deaths show a similar pattern. Cambodia had 21 American drug deaths since 2002, despite only 191,000 American visitors in 2014.[5]
Suicide and Other Overlooked Causes
Suicide is easy to miss in discussions of travel danger. The CDC’s 2019 to 2021 figures list 225 suicides, ahead of drowning or maritime deaths at 206.[2] These deaths often involve residents rather than vacationers. Mexico has the highest count of any country, with 250 since 2002, reflecting how often Americans go there.[5]
Trends are not uniform either. A peer-reviewed analysis in the Journal of Travel Medicine found that deaths from the top three causes declined from a 2010 peak to a trough in 2019.[11] The same study found that proportional mortality ratios for vehicular and non-vehicular accidents rose in 2013 to 2022 compared with the prior decade.[11] In short, the picture changes depending on how you measure it.
Conclusion: A Rare Risk With Predictable Patterns
Mexico has the most recorded non-natural deaths of U.S. citizens abroad, partly because it has by far the most American visitors. Costa Rica, the Dominican Republic and Thailand also appear often. Each has its own dominant hazard, whether drowning, road crashes or motorbikes.
Dying abroad is still uncommon. One analysis noted that an average of 827 Americans died of unnatural causes abroad each year, while tens of millions traveled.[5] The most recent clean country-level data I found covers 2020 to 2023, and the CDC’s 2026 edition relies on 2019 to 2021. The practical lesson holds regardless: the biggest risks are roads and water, so buckle up, skip the scooter, and respect the surf.
