Jacksonville’s child gun violence is concentrated in neighborhoods shaped by segregation and toxic exposure
In Jacksonville, child firearm injury does not appear evenly across the map. It clusters in neighborhoods with a long record of disinvestment, pollution, and racial segregation — the same places where homes rose on land once known as Brown’s Dump, a 250-acre site used for landfill and toxic ash disposal in the mid-20th century.
A boarded-up elementary school named for Mary McLeod Bethune stands on that ground as a blunt reminder of how urban planning, environmental neglect, and public health can collide. For generations, Black children lived, learned, and played in a community built over contamination. The land was later identified as a potential Superfund site, and state and federal officials concluded that the soil posed a potential public health hazard.
The gun violence pattern is not separate from that history. It follows it.
Brown’s Dump and the long reach of environmental injustice
From the late 1940s through the mid-1950s, Jacksonville operated a landfill in the Brown’s Dump area and filled it with toxic ash from municipal incinerators. The Duval County School Board later built a school there, and developers constructed homes and apartment complexes around it. Cleanup of lead, arsenic, and other contaminants did not begin until 2009, years after the school had closed.
The public health consequences did not stop when the dump shut down. Lead exposure in early childhood can alter neurodevelopment, impulse control, and behavior in ways that may echo into adolescence and young adulthood. A study led by researchers at the University of Wisconsin-Milwaukee found that lead exposure in the first six years of life was positively associated with a higher risk of firearm violence in early adulthood. That link offers a biologically plausible explanation for why environmental injury in childhood can reappear later as violence exposure, both as victimization and as participation in dangerous settings.
It is a harsh continuum: polluted soil, damaged development, and later gunfire.
Hospital claims data show a heavy burden on Jacksonville’s Black neighborhoods
Florida hospital billing data from 2018 through 2024 show that more than 4,000 children in the state were hospitalized for firearm injuries, or about 1.5 a day. Jacksonville alone accounted for at least 375 hospitalizations among children under 18 during that period.
The concentration was especially severe in ZIP codes 32206, 32208, and 32209, the same area where Brown’s Dump is located. At least 150 children from those ZIP codes were hospitalized for firearm injuries between 2018 and 2024. Three of Florida’s 10 worst ZIP codes for child firearm injury rates were in Jacksonville, based on an analysis of hospital claims data obtained for this reporting.
Those numbers are not abstract. They describe repeated trauma to children, families, emergency departments, rehabilitation services, and neighborhoods already carrying the weight of other chronic disease burdens. In the city’s north and northwest, poverty, pollution, lead poisoning, cancer, and shootings overlap with unnerving regularity.
Redlining still shapes where harm concentrates
The roots of this violence run back to the 1930s, when federal housing authorities color-coded maps to mark predominantly Black neighborhoods as poor lending risks. Those redlined areas were systematically denied investment, while segregated white neighborhoods were favored for mortgages and infrastructure. Over time, many communities of color were also burdened with waste facilities, industrial pollution, and other environmental hazards.
Jacksonville fits that national pattern. The U.S. Justice Department alleged in 2023 that Ameris Bank practiced redlining in predominantly Black and Hispanic neighborhoods in the city, and the bank later agreed to a $9 million settlement. The case did not create Jacksonville’s inequities, but it showed how the older geography of exclusion continues to influence access to capital, stability, and neighborhood recovery.
Redlining has been outlawed for decades. Its effects remain visible in life expectancy, chronic disease, and violence exposure.
Lead, stress, and violence operate together at the bedside and in the neighborhood
Gun violence rarely has a single cause, and Jacksonville shows why. Lead exposure can impair the developing brain. Segregation can intensify poverty, housing instability, and chronic stress. Environmental contamination can reduce trust in public institutions and limit the resources available to families trying to protect children. Those forces can interact over years, leaving a neighborhood with fewer protective buffers and more risk during every developmental stage.
A.J. Jordan, a community organizer who works with families of gunshot victims, described the daily fear bluntly: “We have to work hard to make sure our kids get home safe.” That fear is grounded in the data. In one city, childhood exposure to toxic waste, institutional neglect, and firearm injury is not a sequence of unrelated events. It is a single history with different clinical presentations.
Jeffrey Goldhagen, a professor emeritus of pediatrics at University of Florida Health Jacksonville and former county health director, has studied the connection between lead exposure and high firearm injury rates. The clinical implication is hard to miss. Public health interventions aimed only at policing violence will miss part of the causal chain if the neighborhood itself has been biologically and socially damaged for decades.
A public health crisis written into the ZIP code
The Florida data cover pediatric firearm hospitalizations, not every shooting or every injury severity, so the burden on Jacksonville may be even broader than the hospitalization counts show. ZIP codes with fewer than 10 cases were suppressed, and the records did not identify patients. Even with those limits, the pattern is unmistakable: the city’s hardest-hit neighborhoods are the ones shaped by redlining, toxic exposure, and long-term divestment.
The practical consequence lands in emergency departments, pediatric wards, and family homes. Children from these neighborhoods are not encountering firearm injury in a vacuum; they are living where the built environment, historical policy, and present-day violence reinforce one another.
A boarded-up school on contaminated land is not just a symbol. In Jacksonville, it is part of the explanation for why gun violence persists where it does, and why the oldest injuries may begin long before a child ever hears a shot.
