Historical redlining and the epidemiology of present-day firearm violence in the United States: A multi-city analysis

Systematic disparities in reporting on community firearm violence on local television news in Philadelphia, PA, USA

Objective

To better understand how community firearm violence (CFV) is communicated to the public, we aimed to identify systematic differences between the characteristics of shooting victims and events covered on television news and all shootings in Philadelphia, PA, a city with escalating CFV incidence.

Methods

We compiled a stratified sample of local television news clips covering shootings that occurred in Philadelphia aired on two randomly selected days per month from January-June 2021 (n = 154 clips). We coded the clips to determine demographic and geographic information about the shooting victims and events and then matched coded shootings with corresponding shootings in the Philadelphia police database. We compared characteristics of shooting victims and shooting event locations depicted in television clips (n = 62) with overall characteristics of shootings in Philadelphia during the study period (n = 1082).

Results

Compared to all individuals shot, victims whose shootings were covered on local television news more likely to be children and more likely to be shot in a mass shooting. The average median household income of shooting locations featured on television was significantly higher than the median household income across all shooting locations ($60,302 for television shootings vs. $41,233 for all shootings; p = 0.002). Shootings featured on television occurred in areas with lower rates of income inequality and racialized economic segregation compared to all shooting locations.

Conclusions

Television news outlets in Philadelphia systematically over-reported shootings of children, mass shootings, and shootings that occurred in neighborhoods with higher median household income, less socioeconomic inequality, and lower rates of racialized economic segregation.

Community-Academic Partnership to Assess the Role of Physical Disinvestment on Firearm Violence in Toledo, OH

Reversing physical disinvestment, e.g., by remediating abandoned buildings and vacant lots, is an evidence-based strategy to reduce urban firearm violence. However, adoption of this strategy has been inconsistent across US cities. Our community-academic partnership sought to support adoption in Toledo, OH, USA, by generating locally relevant analyses on physical disinvestment and firearm violence. We used a spatial case-control design with matching. Physical disinvestment measures were derived from a citywide parcel foot audit conducted by the Lucas County Land Bank in summer 2021. Firearm violence outcomes were incident-level shootings data from the Toledo Police Department from October 2021 through February 2023. Shooting locations were matched to controls 1:4 on poverty rate, roadway characteristics, and zoning type. Exposures were calculated by aggregating parcels within 5-min walking buffers of each case and control point. We tested multiple disinvestment measures, including a composite index. Models were logistic regressions that adjusted for the matching variables and for potential spatial autocorrelation. Our sample included N = 281 shooting locations and N = 1124 matched controls. A 1-unit increase in the disinvestment score, equal to approximately 1 additional disrepair condition for the average parcel within the walking buffer, was associated with 1.68 times (95% CI: 1.36, 2.07) higher odds of shooting incidence. Across all other measures, greater disinvestment was associated with higher odds of shooting incidence. Our finding of a strong association between physical disinvestment and firearm violence in Toledo can inform local action. Community-academic partnership could help increase adoption of violence prevention strategies focused on reversing physical disinvestment.

Historical Redlining and Present-Day Nonsuicide Firearm Fatalities

BACKGROUND

Redlining began in the 1930s with the Home Owners' Loan Corporation (HOLC); this discriminatory practice limited mortgage availability and reinforced concentrated poverty that still exists today. It is important to understand the potential health implications of this federally sanctioned segregation.

OBJECTIVE

To examine the relationship between historical redlining policies and present-day nonsuicide firearm fatalities.

DESIGN

Maps from the HOLC were overlaid with incidence of nonsuicide firearm fatalities from 2014 to 2022. A multilevel negative binomial regression model tested the association between modern-day firearm fatalities and HOLC historical grading (A ["best"] to D ["hazardous"]), controlling for year, HOLC area-level demographics, and state-level factors as fixed effects and a random intercept for city. Incidence rates (IRs) per 100 000 persons, incidence rate ratios (IRRs), and adjusted IRRs (aIRRs) for each HOLC grade were estimated using A-rated areas as the reference.

SETTING

202 cities with areas graded by the HOLC in the 1930s.

PARTICIPANTS

Population of the 8597 areas assessed by the HOLC.

MEASUREMENTS

Nonsuicide firearm fatalities.

RESULTS

From 2014 to 2022, a total of 41 428 nonsuicide firearm fatalities occurred in HOLC-graded areas. The firearm fatality rate increased as the HOLC grade progressed from A to D. In A-graded areas, the IR was 3.78 (95% CI, 3.52 to 4.05) per 100 000 persons per year. In B-graded areas, the IR, IRR, and aIRR relative to A areas were 7.43 (CI, 7.24 to 7.62) per 100 000 persons per year, 2.12 (CI, 1.94 to 2.32), and 1.42 (CI, 1.30 to 1.54), respectively. In C-graded areas, these values were 11.24 (CI, 11.08 to 11.40) per 100 000 persons per year, 3.78 (CI, 3.47 to 4.12), and 1.90 (CI, 1.75 to 2.07), respectively. In D-graded areas, these values were 16.26 (CI, 16.01 to 16.52) per 100 000 persons per year, 5.51 (CI, 5.05 to 6.02), and 2.07 (CI, 1.90 to 2.25), respectively.

LIMITATION

The Gun Violence Archive relies on media coverage and police reports.

CONCLUSION

Discriminatory redlining policies from 80 years ago are associated with nonsuicide firearm fatalities today.

Addressing Systemic Racism and Racialized Violence to Reduce Firearm Injury and Mortality Inequities

This JAMA Forum discusses systemic racism and racialized violence, promising approaches to address inequities in firearm violence, and ways to treat the trauma of gun violence.

A social problem analysis of the 1993 Brady Act and the 2022 Bipartisan Safer Communities Act

In June 2022, the U.S. federal government passed its first major firearm policy since the Brady Handgun Violence Prevention Act of 1993, the Bipartisan Safer Communities Act (BSCA). Summative content analysis was used to explore how the social problem of firearm violence was outlined in both policies, with the goal of extracting the social issue's definition from the policies' approaches to solving it. Both policies do not outline the various types of firearm violence, nor the disproportionate effect of firearm violence on certain populations. This work informs the role of federal policy in defining and monitoring firearm violence as a public health issue, identifying both individual and structural risk and protective factors from an asset-based lens, and allocating preventative efforts in communities that are most affected.

Historic redlining and health outcomes: A systematic review

OBJECTIVE

The purpose of this systematic review was to synthesize the existing literature on the associations between historic redlining and modern-day health outcomes across the lifespan.

METHOD

This review searched PubMed and CINAHL for peer-reviewed, data-based articles examining the relationship between historic redlining and any health outcome. Articles were appraised using the JBI critical appraisal checklist. The results were synthesized using a narrative summary approach.

RESULTS

Thirty-six articles were included and focused on various health outcomes, including cardiovascular outcomes, breast cancer incidence and mortality, firearm injury or death, birth-related outcomes, and asthma outcomes. Most of the included articles (n = 31; 86%) found significant associations between historic redlining and adverse health outcomes such as increased cardiovascular disease, higher rates of preterm births, increased cancer incidence, reduced survival time after breast cancer diagnosis, and increased firearm injury incidence.

DISCUSSION

This review demonstrates the persistent effect of historic redlining on individuals' health. Public health nurses should recognize redlining as a form of structural racism when caring for affected communities and should advocate for policies and programs that advance health equity. Nurse researchers should develop and test multilevel interventions to address systemic racism and improve health outcomes in communities affected by redlining.

Geospatial Analysis of Social Vulnerability, Race, and Firearm Violence in Chicago

INTRODUCTION

Urban firearm violence (UFV) is associated with inequities rooted in structural racism and socioeconomic disparities. Social vulnerability index (SVI) is a composite measure that encompasses both. We sought to understand the relationship between SVI and the incidence of UFV in Chicago using geospatial analysis for the first time.

MATERIALS AND METHODS

Firearm assaults in Chicago 2001-2019 were obtained from the Trace. Locations of incidents were geocoded using ArcGIS and overlaid with census tract vector files. These data were linked to 2018 SVI measures obtained from the Center for Disease Control and Prevention. Shooting rates were calculated by tabulating the total number of shootings per capita in each census tract. We used Poisson regression with robust error variance to estimate the incident rate of UFV in different levels of social vulnerability and Local Moran's I to evaluate spatial autocorrelation.

RESULTS

In total, 642 census tracts were analyzed. The median shooting rate was 2.6 per 1000 people (interquartile 0.77, 7.0). When compared to those census tracts with very low SVI, census tracts with low SVI had a 1.7-time increased incident rate of shootings (incidence rate ratio [IRR] 1.74, 95% CI 1.08, 2.81), tracts with moderate SVI had a 3.1-time increased incident rate (IRR 3.07, 95% CI 2.31, 4.10), and tracts with high SVI had a 7-time increased incident rate (IRR 7.03, 95% CI 5.45, 9.07).

CONCLUSIONS

In Chicago, social vulnerability has a significant association with rates of firearm violence, providing a focus point for policy intervention to address high rates of interpersonal violence in similar cities.

Risk and Protective Factors for Firearm Assault Injuries Among Black Men: A Scoping Review of Research

Black men are disproportionately affected by firearm assaults in the United States, and these disparities are rooted in structural and social inequities. The objective of this scoping review of research was to identify risk and protective factors for firearm assault injuries among Black men at all levels of the social-ecological framework. The search was conducted in 2021. The initial search generated 1,122 articles. Studies were eligible if they (a) included an analysis of modifiable risk or protective factors for firearm assaults among Black men; (b) reported an estimate of correlation, association, or effect between risk or protective factors and firearm assault injuries, firearm violence, and/or firearm homicides; and (c) were published peer-reviewed articles. In all, 19 articles were identified for review. Risk factors identified at each ecological level include the following: (1) Individual: firearm possession/weapon use and criminal legal system interaction; (2) Relationships: gang membership and exposure to other people who have experienced a firearm assault; (3) Community: indicators for socioeconomic status and racial residential segregation; and (4) Societal: historical racist policy. Individual-level substance use had mixed results. Few (26%) studies examined protective factors at any ecological level, but community-level factors like neighborhood tree cover were identified. Future research needs to examine risk and protective factors at the societal level and multiple ecological levels simultaneously leading to more effective multi-level interventions that will guide policy formation. A greater diversity of study designs, research methods, and theoretical frameworks is needed to better understand factors associated with firearm assault among Black men.

Social Vulnerability and Firearm Violence: Geospatial Analysis of 5 US Cities

BACKGROUND

Firearm violence is now endemic to certain US neighborhoods. Understanding factors that impact a neighborhood's susceptibility to firearm violence is crucial for prevention. Using a nationally standardized measure to characterize community-level firearm violence risk has not been broadly studied but could enhance prevention efforts. Thus, we sought to examine the association between firearm violence and the social, structural, and geospatial determinants of health, as defined by the Social Vulnerability Index (SVI).

STUDY DESIGN

In this cross-sectional study, we merged 2018 SVI data on census tract with shooting incidents between 2015 and 2021 from Baltimore, Chicago, Los Angeles, New York City, and Philadelphia. We used negative binomial regression to associate the SVI with shooting incidents per 1,000 people in a census tract. Moran's I statistics and spatial lag models were used for geospatial analysis.

RESULTS

We evaluated 71,296 shooting incidents across 4,415 census tracts. Fifty-five percent of shootings occurred in 9.4% of census tracts. In all cities combined, a decile rise in SVI resulted in a 37% increase in shooting incidents (p < 0.001). A similar relationship existed in each city: 30% increase in Baltimore (p < 0.001), 50% in Chicago (p < 0.001), 28% in Los Angeles (p < 0.001), 34% in New York City (p < 0.001), and 41% in Philadelphia (p < 0.001). Shootings were highly clustered within the most vulnerable neighborhoods.

CONCLUSIONS

In 5 major US cities, firearm violence was concentrated in neighborhoods with high social vulnerability. A tool such as the SVI could be used to inform prevention efforts by directing resources to communities most in need and identifying factors on which to focus these programs and policies.

Spiritual coping behaviors among injured urban black men in Philadelphia

PURPOSE

High rates of firearm injury among urban Black men in the US can lead to long physical and psychological recovery times, worsened by limited access to mental health services. Spirituality can propel positive thoughts, actions, perceptions and behaviors about self and others yet how it is used among Black men recovering from firearm injury is underexplored. This study examined the role of spirituality in the recovery of Black male survivors of firearm injury.

METHOD

Ten injured urban Black men in Philadelphia were interviewed using descriptive phenomenology. A subset of participants from the Emotional Responses and Recovery from Injury in Urban Black Men study who agreed to be recontacted for future studies were enrolled. Informed consent was obtained, semi-structured interviews were conducted via phone and were audiotaped, transcribed, and de-identified. Thematic content analysis was used to understand perceptions of spirituality and to identify spiritual coping behavior themes.

RESULTS

Findings suggest that injured urban Black men engaged in theistic and non-theistic spiritual activities that resulted in positive character development, reduced risk of re-injury, hope, improved mental health and social bonds.

CONCLUSION

Spirituality may serve as a protective factor against firearm re-injury or retaliation by promoting desired behaviors and mental health among injured urban Black men. Combining culturally sensitive spiritual resources and psychotherapy may lead to effective trauma-informed care in addressing spiritual and existential challenges of injured urban Black men who may find spirituality important.

Exposure to Neighborhood Racialized Economic Segregation and Reinjury and Violence Perpetration Among Survivors of Violent Injuries

Importance

Much is unknown about how individual and neighborhood factors converge in the association with risk for violent reinjury and violence perpetration.

Objectives

To investigate the association of exposure to neighborhood racialized economic segregation with reinjury and use of violence against others among survivors of violent penetrating injury.

Design, Setting, and Participants

This retrospective cohort study was performed using data obtained from hospital, police, and state vital records. The study was performed at Boston Medical Center, an urban, level I trauma center that is the largest safety-net hospital and busiest trauma center in New England. The cohort included all patients treated for a nonfatal violent penetrating injury from 2013 to 2018. Patients with no Boston metropolitan area home address were excluded. Individuals were followed up through 2021. Data were analyzed from February to August 2022.

Exposure

American Community Survey data were used to measure neighborhood deprivation using the racialized economic Index of Concentration at the Extremes (ICE) for patient residential address upon hospital discharge. ICE was measured on a scale from -1 (most deprived) to 1 (most privileged).

Main Outcomes and Measures

Primary outcomes were violent reinjury and police-reported perpetration of violence within 3 years of an index injury.

Results

Of 1843 survivors of violence (median [IQR] age, 27 [22-37] years; 1557 men [84.5%]; 351 Hispanic [19.5%], 1271 non-Hispanic Black [70.5%], and 149 non-Hispanic White [8.3%] among 1804 patients with race and ethnicity data), the cohort was skewed toward residing in neighborhoods with higher racialized economic segregation (median [IQR] ICE = -0.15 [-0.22 to 0.07]) compared with the state overall (ICE = 0.27). There were police encounters for violence perpetration among 161 individuals (8.7%) and violent reinjuries among 214 individuals (11.6%) within 3 years after surviving a violent penetrating injury. For each 0.1-unit increase in neighborhood deprivation, there was a 13% (hazard ratio [HR], 1.13; 95% CI, 1.03 to 1.25; P = .01) increase in risk of violence perpetration but no difference in risk for violent reinjury (HR, 1.03; 95% CI, 0.96 to 1.11; P = .38). The greatest occurrence for each outcome was within the first year after index injury; for example, incidents of violence perpetration occurred among 48 of 614 patients (7.8%) at year 1 vs 10 of 542 patients (1.8%) at year 3 in tertile 3 of neighborhood deprivation.

Conclusions and Relevance

This study found that living in a more economically deprived and socially marginalized area was associated with increased risk of using violence against others. The finding suggests that interventions may need to include investments in neighborhoods with the highest levels of violence to help reduce downstream transmission of violence.
