Broken Windows Assessment
Also known as: Broken Windows Disorder Audit, Physical Disorder Assessment, Systematic Social Observation of Disorder, Neighborhood Disorder Audit
Broken windows assessment is the systematic measurement of physical and social disorder — graffiti, litter, broken windows, public drinking, loitering — tied to the hypothesis that visible disorder signals that no one is in control and thereby invites further crime. Stated by Wilson and Kelling in 1982 and put on a rigorous empirical footing by Sampson and Raudenbush's systematic social observation, it turns the metaphor of an unrepaired broken window into a quantified, reliable neighborhood scale.
Key highlights
- Replaces subjective impressions of 'disorder' with a standardized, observer-coded measure comparable across places.
- Distinguishes physical from social disorder, allowing their separate relationships to crime and fear to be examined.
- Ecometric multilevel aggregation yields neighborhood estimates with quantified reliability rather than noisy averages.
- Directly operationalizes an influential, policy-relevant theory, enabling rigorous empirical tests of it.
- Extends naturally to scalable virtual audits using street-view imagery, lowering the cost of large studies.

When to use it
Use broken-windows / disorder assessment when you need a reliable, comparable measure of physical and social disorder across neighborhoods to study its relationship to crime, fear, or health, or to evaluate disorder-reduction and order-maintenance interventions. Systematic social observation is appropriate when you can standardize routes, units, and coding and observe enough units per neighborhood for reliable aggregation. It is less suitable when disorder must be inferred from residents' subjective perceptions alone (which conflate disorder with crime and bias), and analysts should be cautious about treating measured disorder as a clean cause of crime given the strong confounding by underlying structural conditions.
Strengths & limitations
- Replaces subjective impressions of 'disorder' with a standardized, observer-coded measure comparable across places.
- Distinguishes physical from social disorder, allowing their separate relationships to crime and fear to be examined.
- Ecometric multilevel aggregation yields neighborhood estimates with quantified reliability rather than noisy averages.
- Directly operationalizes an influential, policy-relevant theory, enabling rigorous empirical tests of it.
- Extends naturally to scalable virtual audits using street-view imagery, lowering the cost of large studies.
- Field observation is labor-intensive and captures a single time slice, missing temporal variation in disorder.
- Disorder and crime share strong structural antecedents, so observed associations are heavily confounded and hard to interpret causally.
- Coding schemes vary across studies, limiting comparability of 'disorder' scores between projects.
- Observed physical/social disorder can diverge from residents' perceived disorder, which is itself biased by neighborhood composition.
- Reliable neighborhood estimates require many observed units, raising cost and constraining the number of areas studied.

Frequently asked
Does disorder actually cause crime according to broken-windows research?
The evidence is mixed and contested. Wilson and Kelling proposed a causal spiral from disorder to serious crime, but Sampson and Raudenbush's systematic observation found that, except for robbery, the disorder–crime association largely reflected shared structural antecedents like concentrated disadvantage and weak collective efficacy. The current consensus is that disorder is more a symptom of, and sometimes a modest contributor to, the same conditions that produce crime than a clean independent cause.
What is the difference between physical and social disorder?
Physical disorder refers to deterioration of the built environment — graffiti, litter, broken windows, abandoned cars, vacant lots — while social disorder refers to disruptive behavior in public space, such as loitering, public drinking, drug dealing, and fighting. Disorder assessments typically score them as separate scales because they can have different sources and different relationships to crime and fear.
How is observed disorder different from perceived disorder?
Observed (systematically coded) disorder is recorded by trained raters or imagery against a fixed protocol, aiming for objectivity and comparability. Perceived disorder is what residents report, which is valuable but confounded: perceptions are shaped by crime, fear, and the racial and class composition of the neighborhood, so two areas with the same observed disorder can be perceived very differently. Good designs measure both and treat them as distinct constructs.
