Gang Separation as Violence Reduction Strategy: Georgia vs. Other States

85 Data Points 44 Sources 29 Entities Research Date: Mar 8, 2026
This GPS investigative research brief examines the critical failure of Georgia's prison system to implement gang separation strategies that have proven effective in other states like Texas, Arizona, and California. With 31% of Georgia's ~49,000 inmates validated as gang members across 315 gangs, at least 100 homicides in 2024, and a 56% staffing collapse since 2014, gangs effectively control housing units, contraband, and daily life in many facilities. Despite strong evidence that systematic gang separation reduces violence—Arizona saw over 50% reductions in assaults among segregated gang members and 30% system-wide reduction in rule violations—Georgia's $600 million emergency spending proposal explicitly omits gang management reform, relying instead on infrastructure spending and criminal prosecution.

Where this research is used

This page is a research collection: individual facts drawn from the sources listed further down, each traced to where it came from. A research topic brings many collections together into one overview of an issue. The facts on this page feed these 6 topics; open one to see how they fit with the rest of the evidence.

Budget & Spending
Georgia's prison budget rose from $1.53 billion in fiscal 2024 to an all-time peak of $1.91 billion in fiscal 2025, then settled near $1.79 billion for fiscal 2027. Across that arc the money moved toward health contracts, private beds and surveillance technology while the state-operated prison program, food service and education shrank. GPS's own budget series has since corrected several of its earlier headline claims, and the gap between what the state appropriates and what it can show for it remains the central accountability problem.
11,375 data points
Facility Conditions & Infrastructure
Georgia's prison system runs on a physical plant the state's own consultants, auditors and legislators describe as past the end of its useful life: an average prison age above 30 years, 29 of 34 institutions flagged in a January 2023 internal evaluation as needing critical upgrades, and a documented set of failures — broken cell locks, sewage in living areas, mold, failed HVAC, non-functional fire systems — that the Department of Justice in October 2024 found produced unconstitutional conditions. Overcrowding, measured against original design capacity, is the multiplier: facilities built for 750 people hold more than 1,600, the diagnostic prison operates at roughly five times its 500-bed design, and triple-bunking leaves people about nine square feet each. Georgia's response has been a $600 million-plus infrastructure infusion paired with a new 3,000-bed prison, a plan whose own proponents say will take years longer than the funding window it rests on.
8,250 data points
Mortality & Deaths in Custody
Georgia's prison system recorded at least 1,915 deaths in custody between January 1, 2020, and the registry cutoff — a floor, not a total, because the Georgia Department of Corrections reports deaths roughly two months late and stopped publishing cause of death in March 2024. Homicides rose from a ceiling of nine a year (2011–2018) to 142 across 2018–2023, a 95.8% increase in the last three years, while the department's own mortality data classified obvious homicides as unknown and medical examiners recorded at least 44 overdose deaths the department had labeled natural or undetermined. The same reporting collapse now covers suicide, heat death, and medical neglect — the categories in which the state's own records show people dying unattended in cells for days.
8,758 data points
Reform Models & Programs
Georgia operates a statewide cognitive-skills curriculum for parolees, twelve reentry and cognitive programming centers, contracted addiction treatment, step-down units inside its Tier segregation system, and an earned-time credit statute — and the national evidence base for each of those program types is unusually strong. What the record does not contain is current, published, rigorously designed outcome data for most of Georgia's own programs, and the state's direct spending on them amounts to a fraction of one percent of the prison budget. This page sets out what the research verifies, what Georgia actually runs, what it spends, what other states have achieved, and where the evidence stops.
12,091 data points
Staffing Crisis
Georgia's prison system has run correctional officer vacancy rates above 50 percent since 2021, with ten of its largest facilities above 70 percent, according to the U.S. Department of Justice's October 2024 findings and the state's own budget testimony. Turnover compounds the shortfall: 82.7 percent of officers hired between January 2021 and November 2024 left within a year, and Georgia ranks last among the 50 states in correctional officer pay. Federal investigators, state-hired consultants and the Georgia Senate Study Committee have each identified staffing as the primary mechanism behind the violence, delayed medical response and unchecked gang control documented inside the system.
9,994 data points
Violence & Safety
Georgia's prisons kill people at several times the national rate, and the state's own records understate how often. A three-year federal civil rights investigation concluded in October 2024 that Georgia violates the Eighth Amendment by failing to protect incarcerated people from violence and sexual abuse, finding "near-constant life-threatening violence" and gang control of housing units. The documented record runs from 142 homicides in six years to more than 1,400 violent incidents in sixteen months — and a death registry that keeps growing.

Texas gang separation led to dramatic drop in gang-related incidents 1990-1999 Finding
Data from the Texas prison system from 1990 to 1999 showed that after implementing wholesale placement of gang affiliates in restrictive housing, gang-related incidents dropped dramatically. Research by Ralph and Marquart (1991) demonstrated that segregating or transferring gang leaders alone was not sufficient, but wholesale separation of confirmed gang affiliates produced major reductions in both homicide and assault.

The 2015 Ashker v. Governor of California settlement fundamentally transformed California's approach from a status-based system to a behavior-based system.

GDC STG Unit focuses on intelligence, not housing management Finding
The GDC STG Unit's self-described mission is to 'effectively validate STG related persons, gather intelligence on STG related criminal activities, and provide investigative support in all STG related occurrences.'

GDC's response to gang incidents is reactive, not proactive. When conflicts arise, facilities go on lockdown.

Georgia relies on prosecution, not correctional management, for gang strategy Finding
Georgia's primary gang strategy at the state level is criminal prosecution, not correctional management. Texas uses prosecution as one element of a comprehensive strategy that also includes housing-based separation, intelligence-driven classification, and structured exit programs. Georgia relies on prosecution almost exclusively at the state level, with GDC's internal gang management limited to intelligence gathering and reactive lockdowns.
