Crime Mapping: Spatial and Temporal Challenges (2009, background): “Estimates vary, but one quantitative estimate suggests that at least 85% of crime events must be geocoded for subsequent maps to retain overall accuracy (Ratcliffe 2004b).”
The Crime Reduction Effects of Public CCTV Cameras: A Multi‐Method Spatial Approach (2009, methodology): “This dataset contained information about crime type, date, and the x-y coordinates of the crime location, as geocoded by the PPD to a successful geocoding hit rate in excess of 97%; a satisfactory level in excess of minimum geocoding levels estimated through simulation processes (Ratcliffe, 2004).”
The Predictive Policing Challenges of Near Repeat Armed Street Robberies (2012, background): “…successful hot spot policing evaluations has led to significant policy discussions (Mastrofski et al., 2010), scholars have discussed the importance of understanding the temporal stability of crime hot spots before designing strategies focused on hot spots (Johnson et al., 2008; Ratcliffe, 2004b).”
DOES WHAT POLICE DO AT HOT SPOTS MATTER? THE PHILADELPHIA POLICING TACTICS EXPERIMENT* (2015, background): “The Philadelphia Police Department’s automated system achieves geocoding hit rates in excess of 98 percent, so the data are suitable for spatial data analysis (Ratcliffe, 2004).”
An area-based nonparametric spatial point pattern test: The test, its applications, and the future (2016, methodology): “A random sample (with replacement) of the test data set is undertaken, selecting 85% of the entire test data set—this value is based on Ratcliffe (2004), but can be modified in the graphical user interface.”
THE PHILADELPHIA FOOT PATROL EXPERIMENT: A RANDOMIZED CONTROLLED TRIAL OF POLICE PATROL EFFECTIVENESS IN VIOLENT CRIME HOTSPOTS* (2011, background): “The Philadelphia system automatically geocodes crime events with a success (hit) rate in excess of 98 percent, well above an empirically derived minimum acceptable geocoding rate of 85 percent (Ratcliffe, 2004).”
