Uniform Crime Reporting Program Data: County-Level Detailed Arrest and Offense Data, 2014: Codebook
4. Methodology and Processing
Data Collection Methodology
Time Method: cross-section
Data Collector: United States Department of Justice. Federal Bureau of Investigation
Frequency of Data Collection: monthly
Mode of Data Collection: self-enumerated questionnaire
Characteristics of Data Collection Situation: The data for county-level detailed arrests and offenses
are submitted voluntarily by city, county, and state law enforcement agencies. Some agencies receive
forms directly from the FBI and return them directly to the FBI. Many others receive forms from state
collecting programs and return these forms to those programs. The state programs, in turn, forward
the reports to the FBI. Reports are sent out and collected on a monthly basis.
Control Operations: Once received, the FBI checks the agencies' reports for completeness and
arithmetical accuracy. If an unusual fluctuation is detected in an agency's crime count, the FBI
compares those counts with counts from previous reports or compares the frequencies to those of
agencies similar to the agency in question. When necessary, law enforcement agencies are contacted
to correct or explain the figures.
