Civilian impact of cartel violence in southern Mexico

Civilian life in southern Mexico is being reshaped by violence that rarely resembles open warfare but operates like it. Cartel activity has moved far beyond drug trafficking. It now determines who can run a business, who can move freely, who controls land, and who is allowed to live without fear. For millions of civilians, this violence is not episodic or spectacular. It is constant, intimate, and largely invisible beyond the region.

Over the past two decades, organised crime in Mexico has both fragmented and expanded. Dr Nathan Jones, Associate Professor of Security Studies at Sam Houston State University, explains that while two dominant cartels retain national power, Mexico is now home to roughly 500 organised criminal groups. When leaders are arrested or killed, groups rarely disappear. Instead, they splinter, rebrand, and form new alliances. The result is not stability but churn, with violence seeping into new regions, including southern states once seen as peripheral to cartel conflict.

What makes this especially dangerous for civilians is how deeply criminal groups embed themselves in everyday life. Cartels do not only fight each other; they govern. In areas where the state is weak or absent, they collect taxes, enforce rules, resolve disputes, and control access to livelihoods. Protection fees are imposed on tortilla sellers, shop owners, transport workers, market traders, and farmers. These payments increase until businesses collapse or owners flee. Violence is not reserved for rivals; it is deliberately used against ordinary people to enforce obedience.

Mexico’s limited fiscal capacity compounds the problem. The state collects around 17% of GDP in taxes, roughly half the OECD average. This gap translates into underfunded police forces, weak judicial reach, and uneven local governance. Where the state cannot provide security or services, cartels step in, not as benevolent actors but as coercive ones. In some neighbourhoods, cartel control can reduce petty crime. The trade-off is severe: civilians surrender autonomy, income, and the ability to speak freely.

The true scale of violence is difficult to measure. Mexico’s homicide rate is roughly five times higher than that of the United States, and even this figure excludes the disappeared: people whose bodies are never recovered, often deliberately hidden or destroyed. Fear shapes daily behaviour. Children are increasingly drawn into criminal economies as lookouts, couriers, or low-level enforcers. Even appearance can become dangerous. Tattoos, or the perception of tattoos, can be read as threats or signs of gang affiliation, whether real or imagined, placing civilians at risk simply for how they look.

Southern Mexico is also experiencing a marked shift in displacement. Entire communities are thinning out. Internal displacement is rising as families flee cartel-dominated areas. Migration routes are changing as well. Where people once moved north, growing numbers are now crossing south into Guatemala, which some perceive as safer than remaining in cartel-controlled Mexican territory. That reversal is a stark indicator of deteriorating security conditions along Mexico’s southern border.

State responses have produced mixed, and often damaging, results. The militarised crackdown launched in 2006 marked the beginning of Mexico’s modern drug war. Violence surged, particularly in states such as Michoacán. There were short-term gains: targeted operations against specific factions, including in Tijuana around 2010, temporarily reduced killings. But power vacuums followed. New groups moved in, and violence returned in a slower, more diffuse form: daily extortion, intimidation, and sporadic killings that rarely reach national headlines but steadily erode civilian life.

U.S.-Mexico security cooperation, including the $3 billion Mérida Initiative, improved intelligence sharing and disrupted some criminal networks. Yet, as Dr Jones notes, foreign assistance alone cannot reduce violence sustainably. It can weaken cartels’ ability to challenge the state, but without strong local governance, groups adapt. Pressure in one region pushes violence into another, creating what he describes as a persistent “whack-a-mole” dynamic.

Cartels now finance themselves through far more than drugs. Illegal logging, avocado extortion, oil theft, labour trafficking, sex trafficking, and sophisticated fraud are central revenue streams. These activities connect cartel violence directly to global supply chains, tying distant consumers and markets to harm on the ground in southern Mexico.

Looking ahead, the risks for civilians are clear. Violence will continue to shift geographically, turning once-stable areas into sudden flashpoints. Internal displacement is likely to rise. Urban centres will absorb more people fleeing rural zones, increasing pressure on cities already strained by inequality and crime. Permanent military deployments may expand, but without comprehensive strategies to clear, hold, and build governance, they are unlikely to deliver lasting security.

What is missing is not force, but governance. Stability, Dr Jones argues, is often safer for civilians than constant disruption. People need predictable security, functioning institutions, and economic alternatives, not endless cycles of fragmentation and fear. Southern Mexico is not collapsing. It is being hollowed out. The danger lies not in sudden catastrophe, but in the slow, grinding erosion of civilian life that the outside world has learned to look past.
