Padded Victory? Mexico’s Murder Math War

Mexico’s homicide numbers are falling fast, but the size of the drop is the real fight.

Quick Take

Mexico’s federal government says the daily homicide average fell to 47.3 in May 2026, compared with 86.9 in September 2024.
Officials also say 2025 was the lowest homicide year since 2015, with a national rate of 17.5 per 100,000 people.
Independent analysis using official data still shows a sharp drop, but not as large as the government’s headline claim.
The dispute is less about whether violence fell and more about how the government chose the baseline.

What Sheinbaum Is Claiming

President Claudia Sheinbaum has turned the homicide decline into a central proof point for her security strategy. At a morning press conference, officials said the daily average in May 2026 was 47.3 homicides, down 46 percent from 86.9 in September 2024. They also said 2025 ended with 17.5 homicides per 100,000 people, the lowest rate since 2015.

The government’s case is simple on its face: fewer murders, fewer daily killings, and fewer states with rising violence. Reuters reported in January that officials said homicides were down 40 percent from September 2024 to December 2025, while later briefings pushed the figure to 46 percent by extending the comparison to May 2026. That shifting headline number is where the argument starts to fray.

Why Critics Push Back

Critics do not argue that homicides stayed flat. They argue that the comparison is selective. Latinometrics, using official public-security figures, found 23,609 intentional homicide victims in 2025, down 21.5 percent from 2024, not 46 percent. Mexico News Daily also reported that the annual decline in 2025 was about 30.2 percent, which still points to improvement but not to a collapse in violence.

The baseline matters. Sheinbaum’s team compares May 2026 with September 2024, a month that was already unusually high. That can make the drop look larger than a full-year comparison. A separate stat package cited by Gitnux says 2024 was already up 6.1 percent from 2023, which helps explain why the later percentage sounds so dramatic.

There is also a timing problem. Several reports describe the official homicide figures as preliminary, not final. That matters because preliminary public-security counts can change after later verification. In other words, the trend line looks real, but the final size of the drop is still not locked in.

What the Official Numbers Do Show

The strongest fact in Sheinbaum’s favor is that the decline is not imaginary. Mexico News Daily reported that 2025 had the lowest per-capita homicide rate since 2015, and that 26 federal entities saw annual declines. Latinometrics similarly said most states declined, though Sinaloa stood out as the main exception because of cartel fighting. So the broad direction is down.

The harder question is why. Sheinbaum says the fall reflects coordination among security forces, prosecutors, and state governments. That may be true, but the public record cited here does not prove causation. It shows correlation, then invites the reader to trust the policy story. That is a weaker claim than “the strategy caused the drop.”

The Bigger Pattern Behind the Debate

This is not a new Mexican debate. Human Rights Watch has long warned that the country’s violence data can remain troubling even when headline rates improve. InSight Crime has also noted that Mexico’s crime data systems have been criticized for errors, which gives skeptics a reason to question any sweeping victory lap. That history makes officials’ celebration easier to challenge and harder to dismiss.

The most honest reading is mixed. Mexico appears to have recorded a meaningful homicide decline under Sheinbaum, and the drop is large enough to matter politically and publicly. But the government’s clean “halved” framing leans on a favorable starting point and shifting comparison windows. The result is a real improvement wrapped in a stronger headline than the full-year data yet supports.
