For more details see: data source and enrichment methodology; data spreadsheet; offence category.

The large and sudden trend changes appearing above relate more to policy and process changes rather than reflecting sudden social change. The upward movement in numbers on supervision for assaults starting in 1992/93 relates to police process changes and increased focus on domestic violence. The downward movement in numbers on supervision for burglary during the 1980s can be seen to be matched by an opposite trend below indicating a move to a different sanction approach for burglars rather than only social change.
