Wars get the headlines. A civil war can wreck a country's economy and dominate its news for a decade. But if you assume war is the most costly form of violence a society faces, you would be wrong.
In this week's VoxDev Talk, James Fearon (Stanford) joins Tim Phillips to argue that the violence happening quietly inside homes and on ordinary streets does far more damage than war and terrorism combined.
Drawing on his new book Worse Than War (PUP), written with Anke Hoeffler, Fearon estimates that interpersonal violence, meaning homicide, intimate partner violence and severe physical abuse of children, kills and injures more people than war, and costs society more too. Large-scale collective violence hits very few countries in any year. Almost every country carries rates of homicide and assault that exceed the global average for war.
Fearon's argument is not that war does not matter. It is that the interpersonal violence is less dramatic and often hidden from view. There is evidence on what works to reduce it, but we aren't giving the problem the attention it needs.

About James Fearon
James Fearon is the Theodore and Frances Geballe Professor in the School of Humanities and Sciences and professor of political science at Stanford University, and a senior fellow at the Freeman Spogli Institute for International Studies. His research spans civil and interstate war, ethnic conflict, the international spread of democracy, the evaluation of foreign aid and institution building, and the costs of collective and interpersonal violence. He was elected to the National Academy of Sciences in 2012 and the American Academy of Arts and Sciences in 2002.
The book is co-authored with Anke Hoeffler, professor of development research at the University of Konstanz and co-author of Breaking the Conflict Trap, whose work on the economics of civil war includes the influential conflict-trap research with Paul Collier.
Research and concepts discussed in this episode
Interpersonal versus collective violence. The book distinguishes collective violence, perpetrated by organised groups such as states, rebel organisations, terrorists, or criminal gangs, from interpersonal violence, committed by individuals. Interpersonal violence is broken down into homicide, intimate partner violence, and severe physical abuse of children. The central finding is that the average annual cost of interpersonal violence is far larger than that of interstate and civil war, somewhere between five and 20 times larger, with a best estimate of about eight times.
Prevalence, not intensity. The reason interpersonal violence costs more in aggregate is that it is far more widespread. Very few countries experience large-scale collective violence in any given year, but almost all countries carry annual death and injury rates from homicide, intimate partner violence, and child abuse that exceed global average war death and injury rates. For 2000 to 2019, the authors estimate a global annual average of not quite 1.5 deaths per 100,000 people from war and terrorism, against about 7 per 100,000 for homicide.
Intimate partner violence. The authors estimate global annual averages of about 3,300 and 1,600 per 100,000 people for intimate partner physical and sexual assault respectively, which is roughly twice those rates for women specifically.
Severe physical abuse of children. Measured conservatively, capturing beatings far more serious than a mild spanking, the estimates imply that 15% of children aged 14 or younger are subjected to monthly beatings that would be classed as assaults if the victims were adults.
Economic costs versus well-being costs. Civil war can cause severe economic devastation in the worst-affected countries, mainly through reduced growth, and at the global level the strictly economic costs of collective violence may exceed those of interpersonal violence. But economic loss is only one cost. Drawing on methods that use what people pay to avoid risks of death or injury, the authors estimate well-being losses that are far greater for interpersonal violence, because it kills and injures so many more people each year. The authors note that the difficulty of estimating the economic cost of interpersonal violence means their figures probably understate it relative to collective violence.
Why interpersonal violence stays invisible. National media and political debate focus far more on collective violence, partly because it is dramatic and episodic while interpersonal violence is persistent and, happening inside households, often practically invisible. Sustained public and policy attention on the scale of interpersonal violence is itself a step towards reducing its costs.
It is not just "culture". Against the view that little can be done because interpersonal violence is cultural, the authors point to a broad range of programmes and policies with evidence behind them. For homicide and intimate partner violence, measures that reduce alcohol access and consumption. For intimate partner violence and child abuse, adolescent dating programmes and parenting programmes. Across all forms, police reform to improve accountability and training, and more police in countries with low ratios of police to homicides.
Reducing collective violence. There is reasonable evidence that UN peacekeeping operations are a relatively inexpensive way to lower violence in civil war countries and to reduce the chance of war resuming after a peace agreement. The authors note that rising conflict among the permanent five members of the UN Security Council, and sharpening regional rivalries among larger states in conflict-affected areas, have sharply reduced the prospects for new peacekeeping operations for now.
