3 big reasons it’s so hard to tell just how violent the world’s most violent cities are

  • Latin American countries are consistently among the most violent.
  • Exactly how violent they are is harder to measure for social, political, and logistical reasons.

The most recent ranking of the world’s most violent cities by the Mexican research group Security, Justice, and Peace again drew attention to Latin America, home to 42 of the 50 cities on the list.

Latin America is indeed the most violent region, accounting for about 8% of the global population but tallying roughly one-third of the world’s intentional homicides.

While homicide is not the only kind of violent crime, it is generally considered the best measure of it.

“Of all the different types of crime, homicide is probably the easiest to track because there’s nothing more biologically evident than a dead body,” Robert Muggah, the research director at Brazil’s Igarapé Institute and an expert on crime and crime prevention, told Business Insider.

In most places, there are also legal procedures that authorities are supposed to follow when dealing with homicides.

“So unlike, say, assault or robbery or sexual violence or domestic abuse, homicide is one of those variables that across time and space is relatively straightforward to capture,” Muggah said, adding that researchers can draw on a panoply of sources — law enforcement, public-health agencies, nongovernmental groups, the press, and the public — to tabulate and track homicides over time.

But, as Latin America illustrates, there are a number of recurrent challenges that arise when collecting homicide data that complicate efforts to make comparisons and compile rankings.

“Are we looking at national data, state data, city data, and if we are looking at city data, in this case, how are we defining a city?” Muggah said.

A city’s geographic limits can be defined in a number of ways. The UN has three: the city proper, delineated by administrative boundaries; the urban agglomeration, comprising a contiguous urban area; and the metropolitan area, the boundaries of which are based on social or economic connections.

The populations of each of those areas can vary enormously, as can the number of homicides.

“It turns out cities are surprisingly difficult to define. There is no unified or uniform definition of a city, and this has been a source of some consternation for geographers for over a century,” Muggah said.

The Igarapé Institute eschews homicide rankings but does maintaina Homicide Monitor that compiles data on killings, using the urban-agglomeration definition for cities, Muggah said.

The Mexican group adheres to some set of criteria, requiring minimum population of 300,000 people and excluding places with active conflicts, such as Ukraine or Syria.

But the group says in its methodology that whenever possible it includes all the municipalities that it assesses as part of a city — “localities that form a unique urban system, clearly distinguishable from others, independent of the geographic-administrative divisions inside the countries.”

Muggah and his colleagues noted issues with this method in relation to the 2015 ranking, which found Caracas, Venezuela, to be the most violent city. That year, others also said the group based its tally on the homicide total for the metropolitan area of Cali, in southwest Colombia, and, in their view, overstated the number of homicides.

The group’s ranking for 2018, its most recent, put Tijuana, Mexico, at the top of the list, with a homicide rate of 138.26 per 100,000.

Tijuana has seen a precipitous rise in deadly violence, but the city’s public-security secretary disputed its rank, citing the inclusion of the nearby city of Rosarito, Mexico, in the homicide count and the failure to account for Tijuana’s migrant population.

Security, Justice, and Peace rejected the criticism, saying that it based its population count on official numbers and that excluding Rosarito would have actually raised the homicide rate. (Though it did not say why it assessed Tijuana’s metropolitan area and not those of other cities.)

What’s a homicide?

“It turns out there are many kinds of homicide,” Muggah said. “We have homicide that’s intentional. We have homicide that’s unintentional, which we also call manslaughter. We have homicide committed by police, which sometimes isn’t included in the formal homicide statistics.”

Mexico has experienced an alarming increase in homicides, setting records in 2017 and 2018.

Mexico’s official crime data includes two categories for homicide: “homicidio doloso,” which refers to intentional homicides, and “homicidio culposo,” which refers to manslaughter or unintentional homicides.

The most recent tallies for intentional homicides in Mexico in 2017 and 2018 are 28,868 and 33,369, respectively. The totals for all homicides are 46,640 in 2017 and 50,373 in 2018.

While official government tabulations distinguish between unintentional and intentional homicides as they are legally defined in those countries, counts by nongovernmental groups, the media, and the public can elide that distinction, grouping different kinds of lethal violence together.

“And that matters,” Muggah said, “because in some countries, including Mexico and Brazil, when you include police lethality, police killings, which fall under a different category, that can actually significantly augment the overall count.”

In many cases, Muggah added, “those deaths are not what you describe as illegal.”

In 2017, Brazil had 63,880 homicides — 175 killings a day — up 3% from 2016 and a record. (Homicides were trending downwardthrough the first nine months of 2018, but full-year data for 2018 is not yet available.)

In 2017, there was also an increase in the number of people killed by Brazil’s police, rising 20% from 2016 to 5,144 people, or 14 a day. Authorities in Rio de Janeiro state have attracted special scrutiny for their lethality, drawing accusations of extrajudicial executions.

Even when homicide data for a full calendar year is available — which is not always the case; the Security, Justice, and Peace list in some cases extrapolates from partial-year data — it may change over time.

“In many cases, there are outstanding trials and judicial processes that are ongoing to determine … what in fact that lethal outcome was, and that can take months. It can take years,” Muggah said. “Typically though, there’s a delay when governments produce data to issue this information because they’re still dealing with many of the legalities around sorting out homicide.”

Full-year 2017 crime data for Mexico, released in January 2018, put the number of homicide victims at 29,168.

The most recent data for that year, updated in March 2019, indicatesthere were 28,868 homicide victims. (The Mexican government changed its methodology at the beginning of 2018 and updated previous tallies to reflect that.)

There are also 26,000 unidentified bodies in Mexico’s forensic system, and the government estimates that more than 40,000 people are missing. Hidden graves full of unidentified bodies are frequently found all around Mexico.

All of that — coupled with issues such as a lack of prosecution and suspicions about officials manipulating crime data — means Mexico’s homicide totals are subject to change for the foreseeable future.

“In many countries, Latin America, in particular, there are huge impunity rates and a great gap in processing some of these cases, precisely because of the volume but also the lack of capacity to go through all of these cases, and so there’s a reason” for a delay, Muggah said.

It’s necessary to reflect on violence and trends in crime, but, Muggah added, “the challenge is that many governments are operating at different speeds.”

Relaying on data for only part of a year, or drawing on only certain sources that are readily available can often “unintentionally bias our sample,” Muggah said.

A challenge for “all of us who are in the business of monitoring and tracking and building systems to better understand criminality is that there are many places or instances where crime, including lethal violence, is not particularly well reported, or if it is reported it’s reported very badly,” Muggah said.

Latin American countries release crime data fairly regularly, but closer examination reveals “great gaps in the data,” especially in parts of Venezuela, Mexico, and Brazil, Muggah said.

“There’ll be reports that … don’t accurately capture the cause of death, and therefore you get misattribution. There’ll be a situation where they just can’t store the bodies because there’s insufficient space, and so you get undercounts,” he said. “There’ll be places where the governments themselves, police in particular, have no incentive to report on lethal violence and therefore will skew the figures.”

Outside the Organization of Economic Cooperation and Development, a 36-member group that includes most of North America and Europe, available information about crime is also lacking, Muggah said.

“If you go to Africa, with the exception of a few countries, it’s … a knowledge gap around homicide,” he added. That’s also the case inparts of Asia, “where governments just don’t want to report overall statistics on crime, citing it as a national-security issue.”

Incentivizing cities.

In the methodology included in its most recent report, Security, Justice, and Peace said that it compiles the ranking with the objective of “calling attention to violence in cities, particularly in Latin America, so that the leaders are pressured to fulfill their duty to protect the governed to guarantee their right to public security.”

“What we are also looking for is that no one … wants their city or cities to appear in this ranking, and that if their city or cities are [on it] already, they make the maximum effort so they leave it as soon as possible,” the group added.

There are positive and negative potential effects of inclusion on such a list, Muggah said.

“One hopes that as a positive outcome, [inclusion] would incentivize city leaders, business leaders in cities, civic activists, and common citizens to be alert to the many risks that are there and also to seek and strive to find ways to get themselves off that list,” he said.

Stigmatizing cities.

But there can be negative consequences. Reducing a complicated issue such as personal security to a single metric risks sensationalizing the problem and can skew public perceptions, potentially empowering leaders who push hardline punitive responses, Muggah said.

In some cases, it can “stigmatize cities,” Muggah said, affecting foreign and domestic investment, credit ratings, and business decisions. It can also have a particular effect on local economies, especially for tourism, on which many parts of Latin America rely.

“The hope is that by shining a light … on these challenges that somehow this will provoke” a constructive response from the city, its residents, and its leaders, rallying them around a common goal, such as reducing insecurity and getting off that list, Muggah said.

“It’s not clear yet if that in fact has ever happened, whether these lists have contributed positively to social change, and that might be asking too much of a list,” Muggah said.
