What is collective efficacy in simple terms?

It is a neighborhood's strength when neighbors trust one another and expect that someone will step in when problems arise. Research finds that neighborhoods with more of this strength have less crime.

How is collective efficacy different from social capital?

Social capital refers to networks and relational resources among people. Collective efficacy focuses on the willingness and expectation to act on those relationships for a common purpose. A neighborhood can have many ties but low collective efficacy if the will to act is weak.

Collective Efficacy

👥 Sociology By CampusDown Wiki Editorial Team Last updated October 27, 2026

Collective efficacy is a neighborhood's capacity that combines mutual trust and solidarity among neighbors (social cohesion) with their willingness to intervene for the common good (shared expectations for informal social control). It was introduced in 1997 by sociologist Robert Sampson and colleagues in a study of Chicago. It drew attention for findings that, even among equally poor neighborhoods, those with higher collective efficacy have less violent crime, and it has become a core concept in criminology and urban sociology.

Concept and background

In the early twentieth century the Chicago School proposed social disorganization theory, which held that conditions such as poverty, residential turnover and ethnic heterogeneity weaken community bonds and increase crime. Testing the theory with British data, Sampson and Groves (1989) reported that neighborhood structural conditions affect crime through friendship networks, supervision of teenage groups and organizational participation. Sampson, Raudenbush and Earls (1997) went further, defining collective efficacy as the extent to which neighbors trust and help one another and can be expected to step in when, for example, children skip school or spray graffiti.

Findings of the Chicago study

Surveying about 8,800 residents of 343 Chicago neighborhoods, Sampson and colleagues reported that neighborhoods with higher collective efficacy had lower rates of violence and victimization. Much of the effect of structural disadvantages such as poverty and residential instability on violence operated through collective efficacy. Sampson, Morenoff and Earls (1999) showed that collective efficacy differs from social capital, which refers to the quantity of networks, and that the collective efficacy of surrounding neighborhoods also shapes children's environments. Summarizing decades of research, Sampson (2012) argued that neighborhood effects endure over time.

Debates and extensions

Browning, Feinberg and Dietz (2004) pointed to a paradox of social organization in which dense personal ties can shield neighbors who commit crimes and weaken control, concluding that more networks do not always mean more collective efficacy. Reviewing neighborhood-effects research, Sampson and colleagues (2002) emphasized measuring social processes within neighborhoods rather than only their structure. Separately, psychologist Bandura (2000) used collective efficacy to refer to group members' shared belief that they can achieve goals together, extending self-efficacy to the group level. Collective efficacy is often compared with the broken windows theory, which emphasizes disorder, and is widely used in discussions of community crime prevention.
