Notes:

(1) The figures given in the table relate to persons for whom these offences were the principal offences for which they were dealt with. When a defendant has been found guilty of two or more offences it is the offence for which the heaviest penalty is imposed. Where the same disposal is imposed for two or more offences, the offence selected is the offence for which the statutory maximum penalty is the most severe.

(2) Every effort is made to ensure that the figures presented are accurate and complete. However, it is important to note that these data have been extracted from large administrative data systems generated by the courts and police forces. As a consequence, care should be taken to ensure data collection processes and their inevitable limitations are taken into account when those data are used.

(3) The number of defendants found guilty in a particular year may exceed the number proceeded against as the proceedings in the magistrates' court took place in an earlier year and the defendants were found guilty at the Crown Court in the following year; or the defendants were found guilty of a different offence to that for which they were originally proceeded against.

(4) The number of offenders sentenced can differ from those found guilty as it may be the case that a defendant found guilty in a particular year, and committed for sentence at the Crown Court, may be sentenced in the following year.
