From January to September 2025, Mexico’s murder map continued to cluster in familiar places. Government data presented this week show that seven states’ homicides now account for roughly half of intentional killings nationwide, even as the overall pace eased versus last year. Guanajuato again sits at the top, with border and Pacific corridors close behind. The picture is messy: the national daily average fell, but local shocks — from Baja California to Guerrero — continue to shape fear and politics. Here’s what the numbers actually reveal, and why the list is relevant now.
Mexico’s security brief for January–September 2025 highlights a familiar yet uncomfortable truth: violence remains highly concentrated. Official figures presented on Tuesday, October 7, show that seven states account for about 51% of intentional homicides so far this year, even as national totals trend down compared with 2024. The core message came through in the federal briefing. It was highlighted by El Sol de México’s coverage of the latest count — 18,407 homicide victims in the first nine months — alongside the government’s claim that September 2025 was the lowest in a decade.
The seven states of homicide
Which seven? Depending on which outlet summarized the same morning briefing, two rosters circulated. Several reports list Guanajuato, Chihuahua, Baja California, Sinaloa, Estado de México, Guerrero, and Michoacán, with Guanajuato alone accounting for nearly 11% of the national total. Another summary swaps Jalisco for Guerrero. The divergence reflects how some outlets transcribed slides and percentages from the live presentation versus the written release. What is consistent across accounts is the concentration in the Bajío, border, and Pacific corridors.
The government frames the broader picture as an improvement. In its official materials, the Security Ministry said the daily average of homicide victims fell about 32% compared with September 2024, calling last month the “lowest September in 10 years.” That macro point aligns with prior weeks of data and with the president’s communication later in the day, which echoed the 32% claim. The trend is real at the aggregate level; it’s just not evenly felt.
People on the ground live with that unevenness. Take Zacatecas: authorities touted a sharp local decline this year, even as the state pleaded for reinforcement after a rash of highway blockades last week — a reminder that one bad day can overshadow months of better numbers. Border hubs like Tijuana and Pacific nodes in Sinaloa remain pressure points because of trafficking routes, local rivalries, and the stubborn economics of organized crime.
Behind the seven-state concentration is a mix of market logic and institutional drag. States with large illicit economies, major ports, or border crossings tend to bear a greater share of the national burden. Once entrenched, homicide is brutal to shake without years of patient work: targeted policing, local justice that sticks, and prevention programs that scale. The federal brief highlighted those inputs while celebrating the national trend. But residents in the named states judge safety by the week, not the year, and each flare-up can erase trust gains overnight.
What to watch next
Two things deserve close attention in the final quarter. First, whether the “lowest September” claim sustains into October and November — months that often wobble as holidays, local politics, and criminal calendars collide. Second, whether the seven-state list stabilizes or shifts, if Guerrero stays on the list rather than Jalisco — or vice versa — it will indicate where criminal disputes are intensifying and where federal deployments are most significant. Either way, the national story will continue to be written in a handful of places that carry half the pain.
