Exercise caution when interpreting these figures as counting rules and data collection methods
may have changed over time. Please refer to the linked data source(s) for further information.
Data extracts are snapshots drawn from live IT systems at fixed points in time to ensure consistency of
reporting. Although care is taken when entering, processing and analysing the data, the level of detail
collected is subject to the inaccuracies inherent in any large-scale recording system.
Further, these databases are dynamic and where updates to data are made subsequent to the taking of the
extracts, these updates will not be reflected in figures produced by the extract. For this reason,
current figures are unlikely to precisely match those shown here.
