Data users should not rank locales because there are many factors that cause the nature and type of crime to vary from place to place. UCR statistics include only jurisdictional population figures along with reported crime, clearance, or arrest data. Rankings ignore the uniqueness of each locale. Some factors that are known to affect the volume and type of crime occurring from place to place are:
• Population density and degree of urbanization.
• Variations in composition of the population, particularly youth concentration.
• Stability of the population with respect to residents; mobility, commuting patterns, and transient factors.
• Economic conditions, including median income, poverty level, and job availability.
• Modes of transportation and highway systems.
• Cultural factors and educational, recreational, and religious characteristics.
• Family conditions with respect to divorce and family cohesiveness.
• Climate.
• Effective strength of law enforcement agencies.
• Administrative and investigative emphases on law enforcement.
• Policies of other components of the criminal justice system (i.e., prosecutorial, judicial, correctional, and probational).
• Citizens’ attitudes toward crime.
• Crime reporting practices of the citizenry.
