CCR Network Heading

There’s been a 55% decrease over nine years
in domestic violence-related calls to Marin law enforcement!
This trend is not seen anywhere else in California!

Center for Domestic Peace (C4DP) is excited to share highlights from a recent study that tells us why this is happening only in Marin.

When we enlisted Dr. Bill Granados, Ph.D., a nationally recognized criminologist, to study whether there was a link between the decline in calls and C4DP’s work with law enforcement, we discovered that Marin’s rate of calls for assistance has declined steadily since 2013. This drop is statistically significant, meaning the decline is likely not due to random variation or chance.

Updated 12/2022: Bay Area and statewide comparison charts added below with the most recent available data, which brings the chart up to 2021. These numbers are reported in rates, meaning they control for population changes and difference in population between counties.

As you can see, the only story is in Marin. Only two counties saw a decline in DV-related calls for assistance, Marin and Alameda. However, Alameda’s numbers were relatively modest (15% decline) and until 2019, Alameda’s numbers showed very little variation. The county also saw a slight uptick in 2021.

Marin, on the other hand, has seen steadily stronger declines over time, with those declines actually accelerating since 2019. In 2021, the number showed an even more dramatic drop. Overall, Marin has seen a 55% decline since 2013, or has reduced it’s DV-related calls for assistance more than half.
