Neighborhood watch

Evidence Rating  
Evidence rating: Scientifically Supported

Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.

Health Factors  
Date last updated

Residents who participate in neighborhood watches report suspicious or potentially criminal behavior to local law enforcement. Residents work together to help law enforcement solve problems, and are typically led by a block organizer who serves as the liaison with local police1. Some neighborhood watches conduct security surveys and encourage residents to mark their property with personal identifiers2.

What could this strategy improve?

Expected Benefits

Our evidence rating is based on the likelihood of achieving these outcomes:

  • Reduced crime

Potential Benefits

Our evidence rating is not based on these outcomes, but these benefits may also be possible:

  • Reduced vandalism

What does the research say about effectiveness?

There is strong evidence that neighborhood watches reduce crime; watches have been shown to reduce crime between 16 and 26%2. Neighborhood watch programs are also a suggested strategy to prevent vandalism3. Additional study is needed to confirm which neighborhood watch practices most effectively reduce crime2.

A study of neighborhood watch signs suggests that effects of these signs on individuals’ fear of burglary may vary by neighborhoods’ socio-economic condition. Signs appear to increase concerns of burglary in low income neighborhoods, especially when the sign is aged or defaced, but appear to have less effect on concerns about burglary in high income neighborhoods4.

How could this strategy impact health disparities? This strategy is rated no impact on disparities likely.
Implementation Examples

The National Neighborhood Watch and many local law enforcement agencies provide neighborhood watch volunteers with training and materials1.
