Social disorganization theory (Shaw and McKay, 1942) holds that crime concentrates in neighbourhoods where poverty, constant turnover of residents and lack of roots stop the community from policing itself. Broken windows (Wilson and Kelling, 1982) holds that visible, uncorrected disorder —graffiti, litter, broken glass— announces that no one is in charge, drives residents off the street and opens the door to serious crime. The first is a theory of structural causes; the second, a hypothesis about a signal, turned very quickly into policing policy.

// What they shareThe common ground
Both belong to the ecological tradition: they place the explanation in the place, not the people. Shaw and McKay proved it with a finding that remains environmental criminology's best argument: in certain areas of Chicago delinquency rates stayed high for decades even though the population living there changed completely. Both also agree on the intermediate mechanism, which is informal control —neighbours who watch, step in and know one another— and that when that control is lost, the neighbourhood enters a spiral.
// Where they partThe differences that matter
The direction of cause. For social disorganization, disorder and crime are two symptoms of the same thing: a neighbourhood without resources or ties. For broken windows, disorder is a cause of crime. This is the difference most often tested, and Sampson and Raudenbush (1999) found that once poverty and collective efficacy were taken into account, the direct link between disorder and crime almost vanished.
What they propose doing. If the cause is structural, the answer is slow and expensive: housing, jobs, residential stability, associations. If the cause is the signal, the answer is quick: clean, repair and penalise minor offences. From there came the "zero tolerance" policing of 1990s New York, although Kelling denied that this was his proposal.
What kind of text each is. Social disorganization is a theory with an empirical base decades deep. Broken windows was born as a ten-page essay with one of Zimbardo's experiments as its illustration. Its political influence was immense; its scientific standing is still argued over.
// One villain, two readingsOmar Little
The West Baltimore of Omar Little allows both readings, and the series takes sides. With social disorganization you see what lies underneath: a neighbourhood without work since the industry left, families that do not last in the same house, schools that hold on to no one and no institution able to offer a thirteen-year-old anything better than the corner. Omar, Bodie or Michael are not an anomaly; they are what that place produces generation after generation. With broken windows you see the surface: the boarded-up houses, the drugs sold in plain sight. And the series shows what happens when only the surface is dealt with: the sweeps to clear corners improve the figures for a week and change nothing.
The mistake everyone makes
Filing broken windows under social disorganization as if it were its modern version. They share a neighbourhood and a mechanism, but they disagree about the cause, and their practical consequences are almost opposite. The real update of Shaw and McKay is called collective efficacy (Sampson, Raudenbush and Earls, 1997), and it is precisely the one used to cast doubt on broken windows.

Theory questionsFrequently asked questions
What is the difference between social disorganization and broken windows?
Social disorganization attributes crime to a neighbourhood's structural conditions —poverty, residential mobility, lack of ties— which prevent informal control. Broken windows attributes it to visible uncorrected disorder, which signals neglect and attracts more serious crime. For the first, disorder is a symptom; for the second, a cause.
What is collective efficacy?
It is the combination of trust among neighbours and willingness to intervene for the common good. Robert Sampson proposed it in 1997 as a development of social disorganization, and it explains why equally poor neighbourhoods have different crime rates.
Has broken windows theory been proven?
Only in part. There is evidence that disorder raises fear and that acting on specific hot spots reduces crime, but the causal link between minor disorder and serious crime weakens considerably once poverty and neighbourhood cohesion are controlled for.
