Counting rules

Definition

Administrative instructions that specify how agencies should convert incidents into statistical records: how to count multiple victims of one incident, how to classify ambiguous offences, and how to handle series crimes. Changes to counting rules are a major cause of apparent trend shifts that do not reflect real changes in crime.
