Stop and search data is based on the 43 territorial police forces in England and Wales (excludes British Transport Police) between the year ending March 2007 and March 2009. From the year ending March 2010 onwards the collection is based on 44 police forces including British Transport Police.
Population is based on 2011 Census from the Office for National Statistics broken down by ethnicity using the 16+1 ethnic categories and police force area.
There is a total population of 56,075,912 in England and Wales.
Stop and search data is collected by statisticians in Crime and Policing Analysis.
Suppression rules and disclosure control
Ethnicity of individuals stop and searched are collected on a 16+1 self-defined ethnicity codes. A small proportion of individuals did not state their ethnicity these are recorded as 'not reported' in the data. For each financial year the proportion (%) of total stops in the year that were recorded with an ethnicity ‘not reported’ are:
- 2006/07 – 10%
- 2007/08 – 7%
- 2008/09 – 5%
- 2009/10 – 5%
- 2010/11 – 4%
- 2011/12 – 4%
- 2012/13 – 5%
- 2013/14 – 5%
- 2014/15 – 6%
- 2015/16 – 9%
Number of stop and searches are provided as whole numbers to represent the number of persons stopped. Further calculations of proportions and rates are rounded to 2 decimal places.

Further technical information
- These statistics have been assessed by the UK Statistics Authority to ensure they continue to meet the standards required to be designated as National Statistics.
- Under the code of practice for the Statutory Powers of stop and search (see PACE code A), officers are required to make a record of the details of a stop and search at the time of the encounter. On request, they may be required to give a copy of the record to the person searches. This requirement reduces the risk of a stop and search going unrecorded.
- Having a universal code of practice helps to ensures that stop and searches, and their subsequent arrests are standardised across forces, both in terms of the processes involved, and the data recorded.
- A number of forces are moving towards electronic recording of stop and search encounters. This ensures that data is quickly and accurately transferred to force systems. However, this does also present challenges in terms of training officers to record stops in a comparable way.
- Some forces still use paper records to record encounters. These are more likely to involve recording errors, or may not be uploaded into force systems in a timely manner.
- Forces’ use and recording of stop and search are monitored by Her Majesty’s Inspectorate of Constabulary (HMIC). HMIC carries out regular inspections and produce reports on the inspections.
- The Home Office statisticians undertake quality assurance checks which include looking for missing/incomplete data, inconsistencies in the data, extreme values. Trend analyses also look for unusual or unexpected trends in the data. Any inconsistencies or unusual trends are flagged with forces, who are requested to either explain the trends, or resubmit to amend the data. All data are then confirmed by forces during a data reconciliation to confirm they are content for the figures to be published.
Publishing the data
- Some forces publish stop and search data to increase transparency and accountability, as well as to monitor performance. This demonstrates a need for forces to have accurate and reliable data.
