Places Drive Homicide Differences
False Assumption: Differences in firearm homicide rates between adjacent neighborhoods are primarily caused by environmental features of places rather than differences in people.
Written by FARAgent on February 10, 2026
In the early 2010s, University of Chicago economist Jens Ludwig advanced the notion that differences in firearm homicide rates between adjacent neighborhoods stemmed mainly from environmental factors, such as street design and surveillance. He pointed to Chicago's South Shore and Greater Grand Crossing areas, where stark violence gaps seemed tied to "eyes on the street" rather than resident demographics. Ludwig, directing the university's Crime Lab, claimed this explained up to 80 percent of gun violence patterns. Writer Malcolm Gladwell amplified the idea in reviews, praising it as a breakthrough for urban policy. Collaborator Jon Guryan joined Ludwig in related studies, including truancy interventions aimed at fixing neighborhood ills through school attendance.
These views shaped initiatives like Chicago's truancy programs, which poured resources into monitoring absent students under the assumption that place-based fixes would curb crime and boost learning. Results disappointed; the efforts failed to improve outcomes and overlooked deeper patterns, such as black men facing gun death rates 57 times higher than Asian men in the city. Critics noted correlations between murders and racial demographics in neighborhoods, suggesting the focus on environments distracted from human factors.
The debate remains hotly contested today. Mounting evidence challenges the places-over-people theory, with critics arguing it ignores demographic realities and confuses correlation with causation. Proponents defend it as a useful policy lens, while dissenters push for approaches centered on individuals.
People Involved
- Jens Ludwig, an economist at the University of Chicago, promoted the notion that neighborhood environments drive differences in gun violence. He argued for more eyes on the street to interrupt quick disputes. [1]
- Malcolm Gladwell, writing for the New Yorker, endorsed this places theory with enthusiasm. [1]
- Jon Guryan worked with Ludwig on Chicago truancy studies that boosted attendance but failed to improve learning. [1]
- As director of the Crime Lab, Ludwig highlighted adjacent Chicago neighborhoods with similar demographics but different shooting rates to support place over people. [2] He claimed most gun violence stems from rage, not profit. [2]
- Jill Leovy, a reporter for the Los Angeles Times, had earlier described killings as petty disputes in lawless areas through her book Ghettoside, a point Ludwig overlooked. [2]
- Gladwell presented crime concentration in tiny blocks as a revelation. [3]
- Criminologists David Weisburd and Lawrence Sherman noted that a small percentage of blocks account for most crimes, leading to hot-spots policing. [3]
- Analyst Steve Sailer warned that this implies tragic dirt in blocks, often tied to race. [3]

Organizations Involved
The Atlantic interviewed Jens Ludwig and promoted his book by emphasizing neighborhood disparities as proof that places matter more than people. [1] The CDC released data showing stark racial gaps in homicides, which ran counter to place-based theories. [1] The University of Chicago's Crime Lab, under Ludwig, backed research that framed violence as rooted in place features rather than resident differences. [2] The New Yorker ran Malcolm Gladwell's pieces promoting crime concentration in specific places. [3] Hey Jackass compiled Chicago homicide maps that suggested murders spread beyond tiny blocks. [3]

The Foundation
Jens Ludwig pointed to adjacent Chicago neighborhoods like South Shore and Greater Grand Crossing. South Shore had half the murder rate despite their proximity. This seemed to support place effects over people. [1] He suggested violence comes from arguments that eyes on the street could interrupt, an idea that appeared reasonable for low-crime areas but less so for zones with illegal guns. [1] The assumption that truancy drives poor learning felt intuitive, though studies showed it confused cause and effect. [1] Ludwig noted similar economics, race, and ethnicity in Greater Grand Crossing and South Shore, yet twice the shootings in the former. This bolstered claims against people differences. [2] Critics argue this overlooked unmeasured behaviors among residents. [2] The view that only 20 percent of gun violence is profit-motivated propped up the theory, focusing on passion in specific places. [2] Ludwig built on expert estimates to stress situational rage, though growing questions surround its dismissal of impulsive actors. [2] David Weisburd and Lawrence Sherman observed crime in tiny blocks everywhere, a finding that fit neatly and avoided person-based explanations. [3] Mounting evidence challenges this, as Chicago data ties concentration to neighborhoods and demographics. [3]

How It Spread
The Atlantic and New Yorker spread Jens Ludwig's theory through reviews and interviews, highlighting granular place variations. [1] Social scientists steered clear of IQ or race talks due to career risks, which helped environmental explanations gain ground. [1] Ludwig advanced the idea in his academic book, using his Crime Lab role to frame it as a fresh shift. [2] The concept took hold via the hot-spots policing movement in criminology. It pushed back on uniform patrols by focusing on specific places. [3]

“The shock carried over into the hot-spots policing movement that grew out of the observation about crime’s concentration.

Resulting Policies
Hot-spots policing emerged from the assumption. It sent more officers to violent blocks instead of spreading them evenly or targeting demographics. [3]

Harm Caused
By downplaying racial disparities, where black men in Chicago face gun deaths 57 times higher than Asian men, the focus on places has led to less effective interventions than targeted policing. [1] Chicago's truancy programs used up resources but yielded no better outcomes, mixing up causes. [1] Emphasis on places diverts attention from people-driven crime, as murders correlate with black neighborhoods that make up 26 percent of Chicago's population and area. [3] Areas like South Shore saw 35 murders, with violence pushed outward after housing projects near the Loop came down. [3]

Downfall
CDC data revealed racial homicide gaps far larger than neighborhood differences, raising doubts about place theories. [1] Jens Ludwig's truancy study increased attendance but not learning, due to ability mismatches. [1] New York City's shift in policing cut killings by discouraging gun carrying, suggesting people-focused methods succeed. [1] Steve Sailer highlighted earlier work, like his 2015 review of Ghettoside and Jill Leovy's descriptions of disputes among knuckleheads, challenging the novelty and validity of place theories. [2] Chicago's 2024 homicide map from Hey Jackass showed murders across entire neighborhoods like Austin, aligning with racial patterns rather than tiny blocks. [3] Critics argue these points undermine the assumption, though the debate continues.
