Understanding surveillance statistics

- Since 1998 the surveillance of communications has more than trebled
- 525,130 "authorisations" were granted in 2009 to access communications data
- In 2009 there were 9,042 "covert human information sources" (CHIS) excluding MI5, MI6 and GCHQ


Many people, including the media, are often confused when it comes to understanding official figures on surveillance.

Three main sources of official information are published annually:

The Report of the Interception of Communications Commissioner: 2009 report (pdf)


This Report covers the issuing of warrants to intercept communications issued to the MI5, police, Special Branch and other government agencies like the UK Borders Agency. It does not cover warrants issued by the Foreign Office (which runs MI6, external intelligence agency, and Government Communications Headquarters, the UK's world-wide electronic intelligence-gathering agency, based in Cheltenham).

The published figures on warrants issued underwent a major change in 1998. Previously a single figure was published but in that year policy changed and 2,031 warrants were issued plus 172 "modifications". "Modifications" would previously have required the issuing of a new warrant - so to get comparative annual figures the number of new warrants have to be added to the number of "modifications". The 1998 changes meant that:

- previously each service provider used by an individual or organisation required a separate warrant. This was changed so that a warrant is now issued for each individual/organisation/premises and applies to all service providers used by them (phones, mobiles, internet providers, post etc). In simple terms a single warrant replaced maybe four or five separate warrants. And a single warrant can be issued against a whole organisation/premises covering hundreds of people. In theory this change should have meant that the number of warrants/modifications issued should have fallen but they did not, they grew.

- the time period of a warrant was extended, for example, warrants that used to cover three months are extended to six months.

Snapshot

Year              Warrants          Modifications          Total

1998                 2,031                  172                   2,203
2009                 1,706               5,896                   7,602

Since 1998 the surveillance of communications has more than trebled.

This report also gives the figure for "authorisations" given to access "communications data" - which refers to data concerning a phone-call, e-mail, fax, mobile phone-call (and location) and internet usage (which also reveals the "content" of the "communication"). The number of "authorisations" are phenomenal:

- 1 January 2005 - 31 March 2006: 439,054 giving an adjusted annual figure of : 351,243
- 1 April - 31 December 2006: 253,557, giving an adjusted annual figure of: 338,076
- The year 2007: 519,260
- The year 2008: 504,073
- The year 2009: 525,130

The bulk of "authorisations" are made by the police who have automated access to service providers records.

No figures are given for subsequent requests for access to the "content" of communications.
Nor for the number of successful prosecutions resulting for the surveillance.

The Report of the Chief Surveillance Commissioner: 2009-2010 report (pdf)


This report covers property "interference" and "covert human information sources" (CHIS, people asked to, and often paid, to spy covertly). Property "interference" covers homes, hotels rooms, any premises/HQ, and vehicles. The scope includes police and other law enforcement agencies, local councils and government agencies. It does not include property warrants, intrusive surveillance (eg: "bugs" recording conversations) or the use of CHIS for MI5, MI6 or GCHQ.

In the Annual Report (2009-2010) the Commissioner says that there were:

- 2,705 "property interference authorisations" plus 717 renewals, a total of : 3,422
- 384 "intrusive surveillance authorisations" (eg: bugging bedrooms) plus 643 renewals, a total of 1,027
- 15,285 "directed surveillance authorisations" by the police ("Covert", but not intrusive) plus 2.708 are already in place, a total of 16,973
- 8,477 "directed surveillance authorisations" given by "other public authorities" plus 1,287 already in place, a total of 9,764
- 5,320 "covert human information sources" for the police, with 3,722 already in place, a total of 9,042

The Intelligence Services Commissioner: 2009 report (pdf)



As noted above property warrants, intrusive surveillance (eg: "bugs" recording conversations) or the use of CHIS for MI5, MI6 or GCHQ are not covered by the Surveillance Commissioner but by the Intelligence Commissioner (Regulation of Investigatory Powers Act, Part II).

RIPA Part II covers covert surveillance (intrusive and directed) and CHIS ("undercover officers, agents and informants and the like"). While "property warrants" are issued by the Secretary of State (Foreign Office and Home Office) under Section 5 of the Intelligence and Security Act.

No figures at all are given for "property warrants" or "intrusive" or "directed" surveillance or for CHIS (who are described as "authorised to obtain information from people who do not know that this information will reach the intelligence service").
