Over 32,000 domestic violence 911 calls, but there’s still a lot we don’t know: An analysis of Montgomery County, Maryland 911 database

This report examines Montgomery County’s Data base of emergency police calls from 2017-2019 in an
effort to determine whether the 911 calls are appropriately flagged as inter partner violence related,
which would enable government and non-profit domestic violence agencies to identify areas in the
County where IPV is prevalent, establish the degree of violence, provide a baseline for studying trends.
The report finds the current 911 call coding system does not track the total number of emergency calls
related to IP, using non-specific codes that do not adequately describe the type of violence reported, as
well as discrepancies between what is reported by officers on the scene and the resultant coding.
