The data is presented graphically, thus clearly indicating the trends in volumes of offenders managed over time. However, totals for any given date are also tabulated and these can be located by following a link ("data spreadsheet") at the foot of each graph.
In the sequence of graphs presented, offenders are disaggregated according to gender, age, ethnicity, sentence type, offence type and various combinations of these variables. Where relevant, other forms of disaggregation are also applied.
