Every gun on our streets starts somewhere, and the overwhelming majority have their origins in the legal marketplace. Understanding how guns — particularly those that have been diverted from legal commerce to the underground market — make their way to crime scenes is essential to crafting evidence-based and life-saving solutions to the American gun violence epidemic. There is — or should be — nothing controversial about this tracing approach. Epidemiologists and other scientists routinely study the origins of public health challenges in order to develop effective solutions, treatments, and preventative measures. It is a key component of the scientific method. Unfortunately, the best national data on the sources and paths of crime guns has been hidden from researchers, journalists, and the general public for nearly two decades. The gun industry successfully pushed the federal government to restrict public access to this critical gun trace data, and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has aided the industry’s efforts by adopting an overly broad interpretation of those regulatory restrictions. Although some state and local law enforcement agencies have released gun UNDERSTANDING HOW GUNS — PARTICULARLY THOSE THAT HAVE BEEN DIVERTED FROM LEGAL COMMERCE TO THE UNDERGROUND MARKET — MAKE THEIR WAY TO CRIME SCENES IS ESSENTIAL TO CRAFTING EVIDENCE-BASED AND LIFE-SAVING SOLUTIONS TO THE AMERICAN GUN VIOLENCE EPIDEMIC. trace data in the last 20 years, the amount has been insufficient to develop the comprehensive, life-saving solutions that we need. In this report you will find an analysis of the most important gun trace dataset to be publicly available in decades. Attorney General Josh Shapiro of Pennsylvania has released trace data for 186,000 crime guns from over 150 law enforcement agencies in his state, allowing the public to identify, for the first time in decades, which gun dealers appear to supply the most guns to the illegal market. This data is publicly available on the Pennsylvania Gun Tracing Analytics Platform. It is very important to note that the gun tracing dataset, while extensive, is not comprehensive. It does not include crime guns recovered by local Pennsylvania law enforcement agencies that have opted against sharing trace data. For that reason, the findings in this report are not the definitive picture of crime guns in the state. However, this dataset should nonetheless enable the public, policymakers, and law enforcement to hold the gun industry accountable for its role in supplying crime guns — and, in doing so, ultimately save lives. By focusing on the small number of gun dealers now known to be contributing to the problem, Pennsylvanians and their leaders will be able to put political, legal, and economic pressure on the irresponsible actors of the gun industry and bring about needed reforms to ensure that firearms are transferred responsibly and safely. Like all data, gun trace data has its limits; its insights, while key to understanding gun trafficking, are just one part of that process. Earlier this year, Brady unveiled an extensive — and ever-growing — database containing another piece to the puzzle: ATF compliance inspection reports detailing federal firearms licensees (FFLs) who have been issued a warning letter or more severe remedy for cited violations of gun laws. We encourage readers to also view that resource, the Gun Store Transparency Project, at www.gunstoretransparency.org. As you read through these findings, keep in mind that many of the 186,000 crime guns in the database are likely associated with one or more crime victim(s) and their families. If this were not staggering enough, the devastating ripple effects gun violence inflicts on families, neighborhoods, and communities are not captured in these numbers. Brady invites you to join us in advocating for solutions that address the supply side of gun violence. We invite researchers to study this data and build on our analysis; we implore journalists to report on not just the tragic results of gun violence incidents, but how crime guns end up in our communities; we urge lawmakers and law enforcement to adopt life-saving, supply-side solutions to gun violence; and we call on federal, state, and local authorities to be more transparent by releasing more trace data to the public. It is long past time for the gun industry as a whole to adopt meaningful supply-side solutions ensuring firearms are transferred safely and responsibility, as it is neither fair nor just to ask the communities suffering the immense harms of gun violence to also bear the burden of providing all the solutions.

Background: Unstably housed women experience high levels of violence. While previous studies have investigated psychological, physical, and sexual violence, weapon and gun violence are rarely delineated. We examined factors associated with experiencing violence as an adult among unhoused and unstably housed women, with a focus on gun violence. Methods: We recruited women with a history of housing instability from San Francisco homeless shelters, street encampments, free meal programs, low-income hotels, and health clinics. Participants completed interviews including questions regarding both childhood and adult violence. We used multivariable logistic regression to examine associations of specific types of childhood violence (i.e., physical, sexual, gun, and other weapon-involved violence), age, race, ethnicity, educational attainment, and sexual orientation, with risk of experiencing specific types of violence as an adult (i.e., gun, other weapon-involved, physical violence). Because the violence outcomes were not rare, odds ratios were transformed to approximate risk ratios. Results: Nearly half of women (n = 110, 45%) had been attacked with a gun as an adult. Violent victimization in adulthood was common, with 33% having experienced all three forms of violence. The probability of being attacked with a gun as an adult was almost 70% higher among women who had been hit or kicked hard enough to cause injury as a child (RR = 1.68; 95% CI = 1.24, 2.11), and this association was present for all three violence outcomes. No other risk factors explored, including other types of violence experienced as a child, met the statistical threshold to be considered significant. Conclusions: The high prevalence of gun violence reported here is consistent with prior studies of violence conducted in similar populations. Considered in combination with prior research, findings suggest that multi-generational violence prevention interventions for low-income women and girls are needed. They also emphasize the need to more actively include people who experience unstable housing in statewide and national violence surveys to better understand the extent of the problem and address on a broader scale the high rates of violence experienced by unstably housed populations, which have been consistently documented in local research

For a paper that has not yet been through peer review or even been formally published, William English’s "2021 National Firearms Survey" has been remarkably prominent in gun rights advocacy and scholarship. As of June 2024, it has been cited in roughly 50 briefs, invoked at oral argument in the Supreme Court and multiple courts of appeals, and regularly cited in public writings and published academic work.

This response is offered in the spirit of a peer review. Our focus is on methodological issues, questionable statistical results, and problematic conclusions. Because of serious methodological issues, the draft fails to provide a reliable estimate of the number of defensive gun uses, the stock of AR-15s, or the actual protective value of or frequency with which AR-15 type firearms have been used. The paper should not be used as an authoritative source.

Gun violence remains a persistent public health issue in the United States. Two notable risk factors for violence include childhood maltreatment and exposure to community violence. Yet, little is known about the link between childhood maltreatment and gun violence in adulthood and whether a lack of community safety (i.e., increased firearm presence and violence) may explain the association. Objective: This study aimed to investigate the relationship between childhood maltreatment (i.e., emotional abuse and neglect, physical abuse and neglect, and sexual abuse) and firearm violence while examining the potential mediating role of neighborhood concerns among adults hospitalized with violent injuries. Participants and setting: The study included 329 violently injured adults (Mage = 32.7) recruited from a Level 1 Trauma Center in Virginia. Methods: Participants completed assessments of childhood maltreatment, neighborhood concerns, and firearm violence. Results: All forms of childhood maltreatment, except for emotional neglect, were related to firearm violence. Neighborhood concerns partially mediate the relation between both emotional abuse and physical abuse and firearm violence and fully mediate the relation between both sexual abuse and physical neglect and firearm violence. The results show the critical importance of addressing both individual-level trauma and broader social determinants of health (i.e., community violence) in violence prevention efforts. Conclusion: By understanding the pathways through which childhood maltreatment manifests in community settings and contributes to firearm violence, the findings offer valuable insights for informing targeted interventions and policy initiatives aimed at reducing the prevalence of firearm-related violence and fostering safer neighborhood

In light of the difficulty achieving consensus about gun violence prevention at the federal level in the current political climate, leadership and innovation on gun violence prevention must come at the state and local levels. State legislators, law enforcement leaders, and state attorneys general must take the lead to find the pathway that most effectively protects their residents in collaboration with concerned communities. There is substantial evidence that states with comprehensive and effective gun laws have fewer incidents of gun homicides, gun suicides, and unintentional shooting deaths. These 50 proposals for state or local action have demonstrated success where they have been enacted and are a starting point for states interested in promoting public safety by addressing preventable gun violence.

Large capacity ammunition magazines are the common thread running through most mass shootings in the United States. Since 1980, there have been at least 106 mass shootings (three or more fatalities not including the shooter) where the shooter used large capacity ammunition magazines containing more than 10 rounds. A total of 959 people were killed in these shootings, and 1,309 were wounded. This number is likely a significant undercount of actual incidents as there is no consistent collection or reporting on this data. Even in many high-profile shootings, information on magazine capacity is neither released nor reported. The Violence Policy Center has compiled this list of incidents by analyzing news reports and follow-up investigative reports on mass shootings. Only shootings in which there is specific information that large capacity magazines were used are included.  ( This document was last updated on January 11, 2024.

ShotSpotter’s gunshot detection system was deployed in Winston-Salem in August 2021. Since then, nearly 2,000 alerts received a response by Winston-Salem Police.

Results indicate: 

• Improved response to gunfire

  • The response to alerts is significantly quicker than those called in by residents (- 5 min.).

  • ShotSpotter calls received significantly more investigative time, which likely indicates improved evidence recovery.

  • Fewer than one in four ShotSpotter alerts also received a call from residents.

• ShotSpotter produces the following actionable results:

  • Shell casings were recovered in 581 incidents (37.1%)

  • Firearms were recovered in 47 (3%) of alerts.

  • Sixty-seven (3.4%) gun-related arrests are connected to alerts. 

• Deployment of ShotSpotter is related to a reduction in violent gun crimes:

  • Aggravated assaults are down 26% comparing before-after results in the ShotSpotter area.

  • Comparable area and overall city numbers indicate an increase in aggravated assaults during the same period. Comparatively assaults are down 38% in the ShotSpotter community.

  • In real numbers, there are between 51-75 fewer assaults annually in the ShotSpotter area than would be expected. 

• Cost-Benefits:

  • Our estimate suggests that ShotSpotter may save the Winston Salem community between $5 and $8 Million annually.

  • Average annual implementation cost is estimated between $230,000-350,000

  • This indicates a $15-25 return for each dollar spent.

Understanding the source of America’s gun violence epidemic is essential to building effective solutions to prevent it. For decades, laws passed at the behest of the gun industry have shielded important information from public view, making it nearly impossible to understand how, and from where, guns are funneled into the criminal market. Brady has used Freedom of Information Act (FOIA) requests to uncover information in an attempt to better understand how guns make their way from the legal marketplace to ultimately being used in crime. This report examines federal records that identify gun dealers subject to the Bureau of Alcohol, Tobacco, Firearms and Explosives’ (ATF) Demand Letter 2 program — a program created to identify firearms dealers that sell the most crime guns and to aid law enforcement investigations. Only 2% of gun dealers nationwide are subject to this program, which includes dealers who have sold at least 25 guns that were recovered in crime during the past year that were found to have taken less than three years to make it from point of sale to being recovered in that crime. The ATF had identified that this low “time-to-crime” is a strong indicator of gun trafficking. This report, and its underlying national data, are the clearest look we’ve had in two decades as to which gun dealers sell the most crime guns. Absent complete transparency into the gun industry’s role in supplying firearms that fuel our nation’s gun violence epidemic, this data is the best indicator we have as to which gun dealers are fueling crime.

The trafficking of firearms and their use in criminal violence in Europe has received significant attention from researchers and policymakers. Less is known, however, about the illicit proliferation of firearm ammunition and other explosive munitions. Currently, detailed data on illicit munitions in Europe can only be accessed through specialized law enforcement agencies. National seizure statistics often lack the necessary detail for policy-relevant analysis, as do the media reports, which often include incomplete or inaccurate information on the types and calibres of ammunition. 

KEY FINDINGS • Calibres typically associated with handguns and widely available commercial brands of ammunition usually represent the bulk of the illicit firearm ammunition seen in the countries studied. • Illicit firearms ammunition is not necessarily trafficked from abroad, as shown by the misuse of domestically produced cartridges in the five surveyed countries. Moreover, cartridges produced legally within the European Union (EU) have been recovered the same year at crime scenes. • A large percentage of illicit hand grenades and other factory-produced explosive munitions seized in the European countries under review were manufactured in the former Yugoslavia. The seizures are consistent with media reports and government statements indicating that the Balkans are a major source of illicit grenades acquired and used by criminals in the EU. • The number of illicit grenades documented in the Netherlands and Sweden has decreased significantly in recent years, possibly owing to Covid-19-related travel and shipping disruptions, an increased reliance on other types of explosives by criminals, and national and regional counter-trafficking efforts.

This report presents a study on the impact of gunshot detection technology (GDT) on gun violence. The authors leverage over a decade of data from Kansas City, MO, and Chicago, IL, to measure how GDT contributes to policing and public safety. Both cities installed ShotSpotter GDT systems in 2012, allowing for a long-term quasi-experiment of program effects. Kansas City Police Department installed GDT in October 2012, with the target area covering approximately 3.5 square miles of the city and remaining unchanged to this day. Chicago Police Department installed GDT over approximately 3.0 square miles of the city in August 2012 with the coverage area expanding to 22 additional police districts between February 2017 and May 2018. This expansion led to approximately 100 square miles being covered by GDT in Chicago. The GDT system in Kansas City detected 11,517 gunfire incidents through the end of the study period (12/31/2019). The GDT system in Chicago detected 85,572 gunfire incidents over the full installation period from 2/6/17 – 12/31/19.1 Based upon ShotSpotter’s reported annual subscription costs of between $65,000 and $90,000 per square mile2, GDT coverage costs between $227,500 and $315,000 per year in Kansas City and between $8.8M and $12.3M per year in Chicago.

Gun violence is a leading cause of premature death and a driver of racial disparities in life expectancy in the United States. Community-based interventions are the foremost policy strategy for reducing gun violence without exacerbating harm associated with criminal justice approaches. However, little is known about the interventionist workforce. In 2021, we used a researcher-guided survey to obtain a near-census of Chicago violence interventionists (n = 181, 93% response rate). Workers were mostly male (84%) and Black (80.9%), with a mean age of 43.6 years. Interventionists commonly experienced work-related exposure to violence and direct victimization. A total of 59.4% witnessed someone being shot at, whereas 32.4% witnessed a victim struck by gunfire. During work hours, 19.6% were shot at, while 2.2% were nonfatally shot. Single-year rates of gun violence victimization exceeded those of Chicago police. Results suggest that investment in community violence intervention should prioritize improving worker safety and reducing violence exposure while developing support for vulnerable frontline practitioners.

Firearms trafficking in the European Union (EU) is driven by criminal demand and is a key enabler for other criminal activities such as drug trafficking. Criminals seek to acquire firearms for instrumental purposes, namely to facilitate their criminal activities, where they use guns to threaten, intimidate or assault others (criminals or non-criminals), but they can also be acquired for the reputation afforded through the possession of – especially certain types of – firearms. Previous studies have shown that handguns are the type of firearm most commonly possessed by criminals in Europe as they are lightweight, easy to conceal and generally reliable. While automatic rifles can also be very effective for intimidation and assault purposes, their possession by criminals is less common. Criminal demand for firearms comes from various types of criminals ranging from international drug traffickers, armed robbers, youth gangs involved in street drug dealing, human traffickers, loan sharks, professional assassins and so on. Yet not all criminals have equal access to firearms. Given that legal access to firearms is almost impossible for criminals in Europe, they acquire them through other means. These firearms can, for example, be stolen from legal gun owners or state stockpiles, bought from a local criminal arms dealer or trafficked internationall . Interviews with experts, as well as previous studies, suggest also that the criminal demand for firearms is increasing in various EU Member States (9). Due to the traditionally closed character of illicit gun markets in Europe, firearms are often only accessible to criminals when they have the necessary criminal connections. Younger and less experienced criminals tend to experience more difficulties in their attempts to acquire firearms. In the past decade, however, law enforcement agencies from various European countries have noted an increased availability of firearms for criminals in their country. Previous studies have linked this to various trafficking methods, including the continuous supply of conflict legacy weapons from the Western Balkans, the increased trafficking in easy-to-reactivate firearms and in easy-to-convert blank-firing weapons and Flobert-calibre firearms . The possibilities generated by the internet have further eroded the closed character of illicit gun markets in Europe. The increased availability of firearms is believed to have ‘facilitated the gradual trickling-down of the possession and use of firearms to lower segments of the criminal hierarchy in several EU Member States, especially in western Europe’. In 2021 Europol noted that the use of violence in serious and organised crime seemed to be increasing in the EU, both in frequency and severity, augmented by the frequent use of firearms and explosives. A 2021 comparative study on gun violence in Europe, coordinated by the Flemish Peace Institute, concluded that firearms trafficking in Europe is not only driven by criminal demand, but is also strongly connected to criminal gun violence. The observed increased availability of various types of firearms to criminals has led to an escalation of criminal gun violence in several European countries and sometimes also to arms races among criminals. The study also concluded that shootings in the criminal underworld in Europe are mainly connected to the drugs trade and enabled by firearms trafficking. A 2018 EMCDDA study on drug-related homicide concluded that this type of homicide is more likely to involve the use of firearms than other means of violence . Findings from project TARGET state that young men (under the age of 35) are the main victims and perpetrators of lethal gun violence. This is also the case for non-lethal gun violence, but there is a more even age distribution in this category. In 2019 the EMCDDA and Europol noted that the criminal use of firearms, including automatic weapons, by organised crime groups involved in European drug markets appeared to be increasing (16). According to Europol, the use of violence related to the trade in drugs – cocaine and cannabis in particular – has escalated in recent years, and the availability of firearms and explosives is a key enabler for this violence (17). A previous study concluded that more research is needed to uncover the dynamics between drug markets in Europe and gun violence: ‘While there is clearly a link between the illegal drug trade and firearm violence, this connection and its enabling elements are an important avenue for further research’ (18). Counteracting drug-related gun violence requires a good intelligence picture of its scope, characteristics and dynamics. The objective of this report is to analyse the nexus between gun violence and the illegal drug market in Europe. To reach this objective, this paper addresses the following research questions: 1. What is the nexus between firearms trafficking and drug trafficking in the European Union? 2. What are the scope and characteristics of drug-related firearms violence in the European Union? 3. How does this violence impact society?

In an era marked by deep divisions between Republicans and Democrats, few issues are as politically polarizing as gun policy. While a few specific policy proposals continue to garner bipartisan support, the partisan divisions on other proposals – and even on whether gun violence is a serious national problem – have grown wider over the last few years.

Today, just over half of Americans (53%) say gun laws should be stricter than they currently are, a view held by 81% of Democrats and Democratic-leaning independents but just 20% of Republicans and Republican leaners. Similarly, while nearly three-quarters of Democrats (73%) say making it harder to legally obtain guns would lead to fewer mass shootings, only 20% of Republicans say this, with most (65%) saying this would have no effect.

The new national survey by Pew Research Center, conducted from April 5-11, 2021 among 5,109 adults, finds that 73% of Democrats consider gun violence to be a very big problem for the country today, compared with just 18% of Republicans who say the same. The current partisan gap on this question is 11-percentage-points wider than in 2018 and 19 points wider than in 2016.

In 2021, gun violence killed 20,984 people in the United States, more than any single year in the preceding two decades.1 Daily shootings in communities across the country are the most common form of gun violence. On average, 14,062 people are murdered every year by someone using a gun.2 Gun violence is disproportionately concentrated in urban centers, usually in underserved communities of color. Of the more than 13,000 firearm related homicide victims in the US in 2020, 55.8% were Black men.3 Although Black men and boys between the ages 15 and 34 make up just 2% of the nation’s population, they accounted for 37% of gun homicide victims in 2019,4 making homicide the leading cause of death for Black males in this age range.5 According to the American Journal of Medicine, US residents are 25 times more likely to be killed from gun violence than the citizens of any other developed country.6 In addition to its human toll, gun violence imposes a substantial economic cost on society. Direct costs include law enforcement and the criminal justice system, hospital and rehabilitation, incarceration, and victim support. Indirect costs include lost tax revenue, lost business opportunities, reduced property values, and neighborhood population decline and destabilization. When someone is shot, there is an immediate, multifaceted response from an array of government agencies. The fire department dispatches emergency medical technicians (EMTs), government-contracted ambulances respond, and several police department units as well as staff from a city’s office of violence prevention or contracted outreach workers descend on the scene. Investigators from the district attorney’s office also often arrive, and if the victim is declared dead on the scene, the coroner is called. And this is only the immediate aftermath of the shooting. Costs accumulate for many months, even years following a shooting. For surviving victims this includes hospitalization and, in the case of serious injury, rehabilitation–both of which are often paid for by tax dollars. This also includes victim compensation and a protracted investigation by the police department and prosecutors. When there are multiple victims and/ or multiple suspects, the cost of a single shooting incident will increase accordingly.

NICJR has calculated the costs of shootings in numerous cities across the country, deliberately using conservative estimates and only counting documentable direct costs.7 Using these studies as a starting point, this report aggregates the city-specific data and combines it with other data sources to model the direct unit costs and the direct average costs of gun violence nationwide.8 Unit costs reflect all of the potential costs of a single incident of gun violence, while average costs take into account the fact that certain costs are not incurred for every incident. For example, this report estimates the costs that gun violence imposes on the courts, district attorney, and public defender when a suspect is charged and goes to trial. However, because many incidents of gun violence do not result in prosecution or a trial, these estimates, or unit costs, are deflated to calculate the average cost per shooting

NICJR calculates that the unit cost of a single gun-related homicide is just over $1.2 million, while the average cost, or the cost per homicide, is approximately $625,000. This means that, on average, the total direct cost of gun-related homicides in the United States is more than $8.7 billion each year. For non-fatal injury shootings, NICJR calculates the unit cost at almost $700,000, with an average per-shooting cost of about $337,000, for an annual total of $11.7 billion.9 Combined, the total cost of gun homicides and non-fatal shootings is over $20 billion per year. If indirect expenses were included, the total cost of shootings would be much higher.

The Caribbean region suffers from some of the world’s highest rates of violent deaths, with firearms used in the majority of these crimes. Although most homicide victims are men, the Caribbean as a region also faces one of the world’s highest rates of violent deaths among women. While much emphasis has been placed on firearms control at both the political and operational levels, illicit firearms and the dynamics of illicit arms markets in this region have received little research attention. In response, the Caribbean Community (CARICOM) Implementation Agency for Crime and Security (IMPACS) partnered with the Small Arms Survey to carry out a comprehensive evidence-based study of illicit arms trafficking to and within the Caribbean, and the socio-economic costs of firearm-related violence in the region. This Report examines these issues by drawing on data and information collected from 13 of the 15 CARICOM member states and from 22 Caribbean states in total. The study also incorporates the results of original fieldwork undertaken by regional partners, including interviews with prison inmates serving firearm-related sentences, and research in selected hospitals related to gunshot wounds and the associated medical costs and productivity losses for patients..

Gun violence is an American public health crisis decades in the making. The latest Centers for Disease Control and Prevention (CDC) data show that 39,707 people, 86% of whom were male, lost their lives to gun violence in 2019. Gun death data are the most reliable type of gun violence data currently available -- but gun deaths are only the tip of the iceberg of gun violence. With this report, it is our mission to share the most accurate and up-to-date data related to gun deaths while we advocate for more and better data related to gun violence in all its forms. Ultimately, we strive to apply these data to create and implement life-saving policies and programs that will end the gun violence epidemic

Over the last 20 years, several distinct developments have increased the risk of gun violence in American elections.

A marked shift in the US Supreme Court’s approach to the Second Amendment and an aggressive pro-gun movement have caused significant deregulation of guns in some states and cast a shadow of legal uncertainty on strong gun regulations in others. Moreover, as the political system has grown more polarized and prone to violence, politicians have spread disinformation about voting rules to sow distrust in our de

The result: voting and elections have become the targets of threats and intimidation just as the nation faces a proliferation of guns, more frequent gun violence, and fewer legal protections. This is a toxic combination. Still, most states’ laws do not adequately protect voters or the election system.

Although multiple interventions to remediate physical blight have been found to reduce urban firearm violence, there is limited evidence for demolishing vacant buildings as a violence reduction strategy. Starting in 2014, Detroit, MI launched a large-scale program that demolished over 10,000 buildings in its first 3 years. We analyzed the pre-post effects of this program on fatal and nonfatal firearm assaults and illegal drug violations at the U.S. Census block group level, using propensity score matching and negative binomial regression. Receiving over 5 demolitions was associated with a 11% reduction in firearm assaults, relative to comparable control locations, 95% CI [7%, 15%], p = 0.01. The program was associated with larger reductions in firearm assaults for the locations receiving moderate numbers of demolitions (between 6 and 12) than for locations receiving high numbers of demolitions (13 and over). No effects were observed for illegal drug violations and no evidence of spatial crime displacement was detected. These findings suggest that vacant building demolitions may affect gun violence.

Gun violence rates increased in U.S. cities in 2020 and into 2021. Gun violence rates in U.S. cities is typically concentrated in racially segregated neighborhoods with higher poverty levels. However, poverty levels and demographics alone do not explain the high concentration of violence or its relative change over time. In this paper, we examine the extent to which the increase in shooting victimization in Philadelphia, New York, and Los Angeles during the 2020-2021 pandemic was concentrated in gun violence hot spots, and how the increase impacted race and ethnic disparities in shooting victimization rates. We find that 36% (Philadelphia), 47% (New York), and 55% (Los Angeles) of the increase in shootings observed during the period 2020-2021 occurred in the top decile of census block groups, by aggregate number of shootings, and that the race/ethnicity of victims in these gun violence hot spots were disproportionately Black and Hispanic. We discuss the implications of these findings as they relate to racial disparities in victimization and place-based efforts to reduce gun violence.
