Crime analysis
Crime analysis is the systematic collection, preparation, examination, and communication of crime-related information to understand patterns and support decisions.
Crime analysis is the systematic collection, preparation, examination, and communication of crime-related information to understand patterns and support decisions. It can address incidents, locations, times, repeat problems, or other relevant relationships. An analysis identifies findings within its data and method; it does not automatically prove who committed a crime or what caused a pattern.
What analysts contribute
The Bureau of Justice Assistance's capacity guide describes crime analysis as work involving trends, patterns, problems, and reporting to decision-makers. Maps, tables, and briefings can be outputs of that work, but preparing a visual is only one possible part of the process.
Analysts must know what each source counts. A dispatch record, an offense report, and an arrest record describe different stages and units. Combining them without preserving those distinctions can produce a precise-looking result with an unclear meaning.
Example
Hypothetical example: An analyst examines repeated theft reports around parking areas and notices a concentration during a particular time window. The report identifies incomplete location fields and recommends checking the pattern against additional information.
The finding can guide further inquiry. It does not establish that every event has the same offender or that every location in the area has equal risk. The missing fields limit the pattern's completeness.
Common confusion
A crime map displays selected information geographically. Crime analysis includes deciding what to examine, evaluating quality, and interpreting results. A map can support analysis without settling the conclusions.
Correlation describes association; it is not proof of causation or individual responsibility.
Reading the method
Look for the question, data sources, inclusion rules, period, geography, and limitations. A report should distinguish observed counts from estimates or predictions. Comparisons and recommendations are strongest when their assumptions and supporting evidence are visible, rather than inferred from a chart's appearance.
