Police: Databases

Volume 698: debated on Tuesday 5 February 2008

asked Her Majesty's Government:

How many individuals' data are stored on the National DNA Database; and, of those, how many (a) are convicted criminals; (b) are currently serving a sentence; (c) have not been convicted of a crime; and (d) have never been charged with a recordable offence. [HL1307]

On 31 December 2007, there were 4,264,451 individuals with a DNA profile retained on the National DNA Database (NDNAD). Of these, an estimated 4,011,954 were sampled by police forces in England and Wales.

The most recent figures available on the number of convictions of those on the NDNAD were published in an Answer given in another place, (Official Report, Commons, 13 December 2007, col. 761W).

It is not possible to provide details of people who are currently serving sentences except at disproportionate cost. It is not possible to provide details of those who have never been charged with a recordable offence.

asked Her Majesty's Government:

In the past year, how many sets of fingerprints and biological samples have been taken without consent by each police force in England and Wales. [HL1309]

Data on the number of sets of fingerprints taken without consent are not held centrally by the National Policing Improvement Agency (NPIA) and cannot therefore be provided.

Available information relating to DNA samples indicates that approximately 690,000 DNA samples were taken without consent by police forces in England and Wales in 2006-07. The numbers of profiles derived from these samples which were actually loaded on to the DNA database, broken down by force, are shown in the attached table. (Three forces did not return data and figures for these have been estimated). The numbers of samples taken and profiles loaded are higher than the number of persons involved, as some persons are sampled more than once.

asked Her Majesty's Government:

For how many individuals aged 10 to 18 they have bioinformation stored. [HL1515]

As at 21 January 2008, the National DNA Database (NDNAD) held 362,812 profiles from individuals between the ages of 10 and 18 (up to their 18th birthday), from all forces in the United Kingdom, (this includes England, Wales, Scotland, Northern Ireland and the Channel Islands). The number of profiles held on the database is not indicative of the number of individuals. As it is possible for a profile to be loaded on to the NDNAD on more than one occasion, some profiles held on the NDNAD are replicates. This can occur, for example, if the person provided different names, or different versions of their name, on separate arrests.

At present, the replication rate is 13.3 per cent, that is, the number of people whose details are loaded is 13.3 per cent fewer than the number of profiles. Therefore, the estimated number of individuals between the ages of 10 and 18 as at 21 January 2008 is 314,558. Individuals who were under 18 at the time that a DNA sample was taken from them, but were over 18 on this date, are not included in the figures.

The IDENT1 database, which holds fingerprints records, cannot provide information on the ages of individuals.
