Several recent studies have used records of calls‐for‐service (CFS) to police 911 centers to measure crime at the address, neighborhood, and city level. This article examines the limitations of this “new” indicator of crime. After pointing out several types of error in dispatch records, we use data from an observational study of policing in 60 neighborhoods to examine empirically how these errors might bias CFS‐based crime counts and discuss the consequences of such bias. We conclude with suggestions for future research on the validity of CFS as an indicator of crime.
