Note:

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 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.
