DEFINITION: Under general supervision, gathers, categorizes, and
analyzes narrative and statistical data pertaining to past and
current criminal activity; prepares and disseminates reports and
recommendations pertaining to existing and anticipated criminal
activity to sworn personnel in order to increase the effectiveness
of patrol deployment, crime prevention, and the apprehension of
suspects; and performs related duties as required.
DISTINGUISHING CHARACTERISTICS: Incumbents perform
professional-level crime analysis requiring significant education
and experience using statistics and probability, and knowledge of
law enforcement operations. The Crime Analyst is distinguished from
the Crime Data Technician by the Analyst's responsibility for
projects of greater complexity and requiring greater analytical
ability and independent judgment, and for making recommendations
with greater consequence of error. The Crime Analyst is further
distinguished from the Crime Data Technician by the Analyst's
emphasis on long range and far reaching strategic and operational
crime analysis and the use of analytical skills, as opposed to the
latter's emphasis on data collection, the use of specialized law
enforcement databases and software, and tactical crime analysis
involving current crime series in the immediate vicinity.
EXAMPLES OF DUTIES:
1. Conducts research and strategic crime analysis to identify crime
patterns and trends; analyzes long term crime patterns and trends
using probability studies and complex statistical analyses such as
random samplings, correlation, and regression analysis; develops and

physical or vehicle description profiles); forecasts future criminal
2. Prepares strategic action plans; assists operations and
management personnel in planning the deployment of resources for the
