In 2024, Colima in Mexico ranked as the world's most dangerous city with a homicide rate of 140 per 100,000 inhabitants. Seven of the 10 cities with the highest murder rates worldwide are all found in Mexico. The list does not include countries where war and conflict exist. Latin America dominate murder statistics Except for Mandela Bay, all the cities on the list are found in Latin America. Latin America also dominate the list of the world's most dangerous countries. Violence in Latin America is caused in great part by drug trafficking, weapons trafficking, and gang wars. Crime in South Africa Mandela Bay in South Africa is the only city outside Latin America among the 10 most dangerous cities worldwide. The country is struggling with extremely high levels of inequality, and is struggling with high levels of crime and power outages, harming the country's economy and driving more people into unemployment and poverty.

This statistic displays the most polluted cities in the world based on PM2.5 concentrations in 2016. During this year, Patna, India had an average PM 2.5 concentration of 149 micrograms per cubic meter. The World Health Organization recommends that PM2.5 levels should not exceed 10 micrograms per cubic meter.

In 2023, around 3,640.56 violent crimes per 100,000 residents were reported in Oakland, California. This made Oakland the most dangerous city in the United States in that year. Four categories of violent crimes were used: murder and non-negligent manslaughter; forcible rape; robbery; and aggravated assault. Only cities with a population of at least 200,000 were considered.

In 2022, the New Orleans-Metairie, LA metro area recorded the highest homicide rate of U.S. cities with a population over 250,000, at 27.1 homicides per 100,000 residents, followed by the Memphis, TN-MS-AR metro area. However, homicide data was not recorded in all U.S. metro areas, meaning that there may be some cities with a higher homicide rate.

St. Louis

St. Louis, which had a murder and nonnegligent manslaughter rate of 11.6 in 2022, is the second-largest city by population in Missouri. It is home to many famous treasures such as the St. Louis Cardinals baseball team, Washington University in St. Louis, the Saint Louis Zoo, and the renowned Gateway Arch. It is home to many corporations such as Monsanto, Arch Coal, and Emerson Electric. The economy of St. Louis is centered around business and healthcare, and in addition is home to ten Fortune 500 companies.

Crime in St. Louis

Despite all of this, St. Louis suffers from high levels of crime and violence. As of 2023, it was listed as the seventh most dangerous city in the world as a result of their extremely high murder rate. Not only does St. Louis have one of the highest homicide rates in the United States, it also reports one of the highest numbers of violent crimes. In spite of high crime levels, the GDP of the St. Louis metropolitan area has been increasing since 2001.

In 2023, the Mexican city of Colima was the most deadly city in the world, with a murder rate of 140.32 per 100,000 inhabitants. 7 out of the top 10 cities with over 250,000 habitants and the highest homicide rates were located in Mexico.

Saint Kitts and Nevis saw a murder rate of 65 per 100,000 inhabitants, making it the most dangerous country for this kind of crime worldwide as of 2023. Interestingly, El Salvador, which long had the highest global homicide rates, has dropped out of the top 20 after a high number of gang members have been incarcerated. Meanwhile, Celaya in Mexico was the most dangerous city for murders. Violent conflicts worldwide Notably, these figures do not include deaths that resulted from war or a violent conflict. While there is a persistent number of conflicts worldwide, resulting casualties are not considered murders. Partially due to this reason, homicide rates in Latin America are higher than those in Afghanistan or Syria. A different definition of murder in these circumstances could change the rate significantly in some countries. Causes of death Also noteworthy is that murders are usually not random events. In the United States, the circumstances of murders are most commonly arguments, followed by narcotics incidents and robberies. Additionally, murders are not a leading cause of death. Heart diseases, strokes and cancer pose a greater threat to life than violent crime.

In 2024, the highest homicide rate among 22 Latin American and Caribbean countries surveyed was in Haiti, with around 62 murders committed per 100,000 inhabitants. Trinidad and Tobago came in second, with a homicide rate of 46, while Honduras ranked seventh, with 25. In the same year, the lowest rate was recorded in El Salvador, with a homicide rate of 1.9 per 100,000 inhabitants. A violence-ridden region Violence and crime are some of the most pressing problems affecting Latin American society nowadays. More than 40 of the 50 most dangerous cities in the world are located in this region, as well as one of the twenty countries with the least peace in the world according to the Global Peace Index. Despite governments’ large spending on security and high imprisonment rates, drug and weapon trafficking, organized crime, and gangs have turned violence into an epidemic that affects the whole region and a solution to this issue appears to be hardly attainable. The cost of violence in Mexico Mexico stands out as an example of the great cost that violence inflicts upon a country, since beyond claiming human lives, it also affects everyday life and has a negative impact on the economy. Mexicans have a high perceived level of insecurity, as they do not only fear becoming victims of homicide, but also of other common crimes, such as assault or rape. Such fear prevents people from performing everyday activities, for instance, going out at night, taking a taxi or going to the movies or the theater. Furthermore, the economic toll of violence in Mexico is more than considerable. For example, the cost of homicide and violent crime amounted to 2099.8 and 1778.1 billion Mexican pesos in 2023, respectively.

OVERVIEW

2019 had the most mass killings since at least the 1970s, according to the Associated Press/USA TODAY/Northeastern University Mass Killings Database.

In all, there were 45 mass killings, defined as when four or more people are killed excluding the perpetrator. Of those, 33 were mass shootings . This summer was especially violent, with three high-profile public mass shootings occurring in the span of just four weeks, leaving 38 killed and 66 injured.

A total of 229 people died in mass killings in 2019.

The AP's analysis found that more than 50% of the incidents were family annihilations, which is similar to prior years. Although they are far less common, the 9 public mass shootings during the year were the most deadly type of mass murder, resulting in 73 people's deaths, not including the assailants.

One-third of the offenders died at the scene of the killing or soon after, half from suicides.

About this Dataset

The Associated Press/USA TODAY/Northeastern University Mass Killings database tracks all U.S. homicides since 2006 involving four or more people killed (not including the offender) over a short period of time (24 hours) regardless of weapon, location, victim-offender relationship or motive. The database includes information on these and other characteristics concerning the incidents, offenders, and victims.

The AP/USA TODAY/Northeastern database represents the most complete tracking of mass murders by the above definition currently available. Other efforts, such as the Gun Violence Archive or Everytown for Gun Safety may include events that do not meet our criteria, but a review of these sites and others indicates that this database contains every event that matches the definition, including some not tracked by other organizations.

This data will be updated periodically and can be used as an ongoing resource to help cover these events.

Definition of "mass murder"

Mass murder is defined as the intentional killing of four or more victims by any means within a 24-hour period, excluding the deaths of unborn children and the offender(s). The standard of four or more dead was initially set by the FBI.

This definition does not exclude cases based on method (e.g., shootings only), type or motivation (e.g., public only), victim-offender relationship (e.g., strangers only), or number of locations (e.g., one). The time frame of 24 hours was chosen to eliminate conflation with spree killers, who kill multiple victims in quick succession in different locations or incidents, and to satisfy the traditional requirement of occurring in a “single incident.”

Offenders who commit mass murder during a spree (before or after committing additional homicides) are included in the database, and all victims within seven days of the mass murder are included in the victim count. Negligent homicides related to driving under the influence or accidental fires are excluded due to the lack of offender intent. Only incidents occurring within the 50 states and Washington D.C. are considered.

Methodology

Project researchers first identified potential incidents using the Federal Bureau of Investigation’s Supplementary Homicide Reports (SHR). Homicide incidents in the SHR were flagged as potential mass murder cases if four or more victims were reported on the same record, and the type of death was murder or non-negligent manslaughter.

Cases were subsequently verified utilizing media accounts, court documents, academic journal articles, books, and local law enforcement records obtained through Freedom of Information Act (FOIA) requests. Each data point was corroborated by multiple sources, which were compiled into a single document to assess the quality of information.

In case(s) of contradiction among sources, official law enforcement or court records were used, when available, followed by the most recent media or academic source.

Case information was subsequently compared with every other known mass murder database to ensure reliability and validity. Incidents listed in the SHR that could not be independently verified were excluded from the database.

Project researchers also conducted extensive searches for incidents not reported in the SHR during the time period, utilizing internet search engines, Lexis-Nexis, and Newspapers.com. Search terms include: [number] dead, [number] killed, [number] slain, [number] murdered, [number] homicide, mass murder, mass shooting, massacre, rampage, family killing, familicide, and arson murder. Offender, victim, and location names were also directly searched when available.

This project started at USA TODAY in 2012.

The statistic shows the homicide rate worldwide in 2010, by region. In 2010, the homicide rate of Africa stood at 17.4 homicides per 100,000 of population.

A ranking of the most dangerous cities in the world based on murder rate per capita can be found here.

In 2024, Pietermaritzburg (South Africa) ranked first in the crime index among African cities, with a rating of roughly 83 index points. The six most dangerous areas on the continent were South African cities. The index estimates the overall level of crime in a specific territory. According to the score, crime levels are classified as very high (over 80), high (60-80), moderate (40-60), low (20-40), and very low (below 20). South Africa’s crime situation According to the crime index ranking, South Africa was the most dangerous country in Africa in 2023, followed by Somalia, Nigeria, and Angola. Murder and organized crime are particularly widespread in South Africa. In 2023, the country had one of the highest murder rates globally, registering around 36 homicides per 100,000 inhabitants. Moreover, South Africa’s crime scene is also characterized by the presence of organized criminal activities, for which the country ranked third in Africa. Reflecting these high levels of crime, a survey conducted in 2023 showed that around 56 percent of South Africans were worried about crime and violence in the country. Crime risks in Africa The African continent hosts some of the most dangerous places worldwide. In 2023, South Sudan and the Democratic Republic of the Congo were the least peaceful countries in Africa, according to the Global Peace Index. Worldwide, they ranked fourth and fifth, respectively, behind Afghanistan, Yemen, and Syria. Terrorism is a leading type of crime perpetrated in Africa. Home to Boko Aram, Nigeria is among the countries with the highest number of terrorism-related deaths globally. Furthermore, Burkina Faso had the highest number of fatalities in the world. Human trafficking is also widespread, predominantly in West Africa. The most common forms of exploitation of victims of trafficking in persons are forced labor and sexual exploitation.

In 2024, six of the eight Brazilian cities with the highest homicide rates were in the Northeast. Feira da Santana led the ranking of the most violent city in Brazil, with a murder rate of 55.63 per 100,000 inhabitants. It was followed followed by Recife, with a homicide rate of more than 41 per 100,000 inhabitants. In Latin America and the Caribbean, Feira da Santana was the 22nd most deadly city.

In January 2024, the most usual type of crime reported in Mexico was domestic violence. In that month, the cases of this type of violence amounted to around 20,814 cases. Regarding property crimes, the highest number of occurrences were vehicle thefts, with nearly 11,887 reported crimes.

Domestic violence Domestic violence stands out as the crime with the highest incidence and, paradoxically, one of the least attended to by the government. Public spending allocated to combat domestic violence has been dismally low, with a value only around 25 percent of the spending on the military. Adding to the concern, this budget has witnessed a consistent decrease each year since 2015. This decline in resources has had severe consequences, leading to a surge in domestic violence crimes, with many resulting in homicides. It's noteworthy that the majority of registered femicides occur within the confines of closed domestic spaces and are often committed by the partners of the victims. This paints a concerning picture of the challenges faced in addressing and preventing domestic violence.

Mexico and the most violent cities in the world
Mexico hosts seven of the most dangerous cities globally, with Celaya ranking as the number one in terms of murder rate, registering a staggering 109.39 homicides per 100,000 inhabitants and the most of these other cities are concentrated in the upper region of the country, highlighting the significant regional variations in safety and security. On the other hand, the capital, Mexico City, has experienced a decreasing trend in crime incidence, with a notable decrease from 2018 to 2022, nonetheless, the crime rate is still high. As a result, crime and insecurity have become the primary concern for nearly half of the country's population, underscoring the pressing need for addressing these issues.

In Europe, the Baltic countries of Latvia and Lithuania had the highest and third highest homicide rates respectively in 2022. Latvia had the highest rate at over four per 100,000 inhabitants. Meanwhile, the lowest homicide rate was found in Liechtenstein, with zero murders The most dangerous country worldwide Saint Kitts and Nevis is the world's most dangerous country to live in in terms of murder rate. The Caribbean country had a homicide rate of 65 per 100,000 inhabitants. Nine of the 10 countries with the highest murder rates worldwide are located in Latin America and the Caribbean. Whereas Celaya in Mexico was listed as the city with the highest murder rate worldwide, Colima in Mexico was the city with the highest homicide rate in Latin America, so the numbers vary from source to source. Nevertheless, several Mexican cities rank among the deadliest in the world when it comes to intentional homicides. Violent conflicts worldwide Notably, these figures do not include deaths that resulted from war or a violent conflict. While there is a persistent number of conflicts worldwide, resulting casualties are not considered murders. Partially due to this reason, homicide rates in Latin America are higher than those in countries such as Ukraine or the DR Congo. A different definition of murder in these circumstances could change the rate significantly.

Real travel times in Dublin are 66 percent longer than travel under free-flow conditions, making it the most congested urban sprawl in the world as of 2023. This figure refers to additional average travel time throughout the week. Tackling trust in transport With trust in public transport globally taking a knock following the outbreak of Covid-19, switching to public transport modes for commuting trips to save time, emissions, and traffic may prove difficult. Activities at transit stations declined in many cities around the world as a result of ebbing demand amid the coronavirus pandemic. Consequently, transport services in highly populated cities have suffered devastating financial losses. While public transport transit had started to pick up in the beginning of 2021, it could not offset the drop recorded as a result of the pandemic. India: a climate for new policies? Among the twelve cities displayed, India is represented by three. To tackle high levels of congestion, a congestion pricing policy was recently proposed in India, which would serve to introduce parking fees and thus push commuters to take public transport rather than drive their cars to work. Surveys collecting public opinion on this proposal have indicated that this would be a popular policy, should it be implemented. The motive behind curbing congestion in the nation’s largest cities is more than just to reduce pollution levels and time spent in traffic; India has some of the highest levels of traffic-related fatalities globally: some 151,100 people died in traffic accidents in 2019 – this is the highest number on record since 2005.

In 2024, there were nearly 26.20homicides per 100,000 inhabitants in the country, down from a homicide rate of 26.8 a year earlier. Since 2017, when it peaked, the homicide rate in Venezuela has been decreasing year after year.

Falling homicide rate but still higher than the Latin American average The country held the fifth position for the highest homicide rate in Latin America, recording 26.2 homicides per 100,000 inhabitants in 2024, even after experiencing a steady decrease in the rate over the years. In line with this alarming rate, the Venezuelan city of Cumana was ranked as the 11th most dangerous city in the world in 2023, reporting a rate of 62.42. Among these homicide cases, the majority, approximately 5,800, are still under investigation, while the remainder falls into categories of closed cases, those resisting authority, or have been categorized as disappearances, painting a grim picture of the challenges faced in addressing violent crime.

Corruption in Venezuela In the corruption index, which ranges from 0 representing the worst case to 100 signifying no corruption, Venezuela has earned the unfortunate distinction of being the most corrupt country in Latin America, with a meager score of 10 in 2024. Moreover, the estimated corruption control score has been steadily declining, reaching -1.69 in 2024, where lower numbers indicate a higher degree of corruption, painting a worrisome picture. To compound matters, the risk of money laundering and terrorist financing has persistently remained at a high level, recording a score of 7.59 during 2024.

The Croatian capital ranked as the worst city for overtourism or mass tourism in Europe in 2019, registering 36 tourists per inhabitant in that year. Meanwhile, the following three cities in the list recorded 21 tourists per inhabitant. Several European cities associated with overtourism have been forced to implement measures to tackle this problem.

What is “overtourism”?

‘Overtourism’ is a term coined by the travel and tourism industry to refer to problems arising from high numbers of tourists concentrated in a destination. Problems can range from environmental, such as the damage high tourism intensity has on the ecology of a destination, to the societal, in the impact that tourism has on local life and the economy.

Sustainable tourism growth

Europe is the most visited region in the world. Although governments recognize travel and tourism’s economic contribution, destinations have been forced to address dissatisfaction among locals and increased pressure on local resources. The United Nations has already developed a plan to achieve sustainable tourism goals worldwide within the next years, including engaging local populations in development and advancing urban infrastructure. Other local initiatives include attempts to reduce the number of large cruise ships at popular port destinations and encouraging visitors to stay in nearby destinations and to contribute to local businesses.

In 2023, the state with the highest crime rate in the United States per 100,000 inhabitants was New Mexico. That year, the crime rate was 3,636.83 crimes per 100,000 people. In comparison, New Hampshire had the lowest crime rate at 996.11 crimes per 100,000 people. Crime rate The crime rate in the United States has generally decreased over time. There are several factors attributed to the decrease in the crime rate across the United States. An increase in the number of police officers and an increase in income are some of the reasons for a decrease in the crime rate. Unfortunately, people of color have been disproportionately affected by crime rates, as they are more likely to be arrested for a crime versus a white person. Crime rates regionally The District of Columbia had the highest rate of reported violent crimes in the United States in 2023 per 100,000 inhabitants. The most common crime clearance type in metropolitan counties in the United States in 2020 was murder and non-negligent manslaughter. The second most dangerous city in the country in 2020 was Detroit. Detroit has faced severe levels of economic and demographic declines in the past years. Not only has the population decreased, the city has filed for bankruptcy. Despite the median household income increasing, the city still struggles financially.

Mogadishu in Somalia led the ranking of cities with the highest population density in 2023, with 33,244 residents per square kilometer. When it comes to countries, Monaco is the most populated state worldwide.

Santa María – a Peruvian city located to the west of the Andes mountain range – was the most polluted city in Latin America in 2024, based on fine air particulate matter concentration (PM2.5). That year, the city reported an average PM2.5 concentration of 53.4 micrograms per cubic meter. This was followed by Coyhaique, located in Chile, with an estimated PM2.5 concentration of around 40.5 μg/m³. Pollution in Latin American capitals The Chilean capital, Santiago, registered an average PM2.5 concentration of 21.3 μg/m³ in 2023. Lima, the Peruvian capital, had an estimated PM2.5 concentration of around 19.7 μg/m³, while in the capital of Mexico (Mexico City), air pollution amounted to 22.3 μg/m³. The World Health Organization's air quality standards recommend a maximum annual average concentration of 10 μg/m³. The burden of pollution on health Air particulate pollution has been associated with an increase in mortality from cardiovascular and respiratory diseases, as well as development of lung cancer. This is specially concerning considering that nearly 2.8 billion people worldwide are exposed to hazardous levels of air pollution. In particular, South Asia was home to the countries with the highest exposure to hazardous concentrations of air pollution in 2022.
