Data Quality Statement
- To produce this annual release on drug seizures, the Scottish Government requests data on drug supply-related crimes from Police Scotland's Analysis and Performance Unit ( APU). APU, in turn, requests this information from divisions across Police Scotland which still maintain aspects of their own Crime Management Systems defined by the previous legacy force areas.
- Data from drug possession crimes is collected via a random sample of 400 drug possession crime records per year. This sample is stratified by police division so that the sample's geographic distribution reflects the distribution of drug possession crimes across Scotland. These records are reviewed by Scottish Government statisticians.
- As part of the sampling process, the quality of the recording of drug possession crimes was checked and found to be very good, with nearly 100% of records classified correctly across 2016-17.
