Reexamining the Minneapolis Repeat Complaint Address Policing (RECAP) Experiment, 1986-1987

Published by National Institute of Justice | Department of Justice | Metadata Last Checked: November 14, 2025 | Last Modified: 2006-01-12T00:00:00
This study reexamines REPEAT COMPLAINT ADDRESS POLICING: TWO FIELD EXPERIMENTS IN MINNEAPOLIS, 1985-1987 (ICPSR 9788). The original Repeat Complaint Address Policing (RECAP) experiment was a field study of the strategy of problem-oriented policing, which used control and treatment groups consisting of specific addresses in the city of Minneapolis. The impact of problem-oriented policing was measured by comparing the number of 911 calls received for each address during a baseline period to the number received during a period when experimental treatments were in effect. Several features of the original data distort the one-to-one correspondence between a 911 call and an event, such as the occurrence of multiple versions of the same call in the databases. The current study identifies and attempts to correct these occurrences by applying multiple levels of data cleaning procedures to the original data to establish a better one-to-one call-to-event correspondence.
