Genetics: Databases

Volume 481: debated on Monday 27 October 2008

To ask the Secretary of State for the Home Department how many people are profiled on the national DNA database who had samples taken whilst they were under 18 years of age; and how many of these are now adults and have not been charged or cautioned with an offence, broken down by sex. (198642)

Table 1 shows the numbers of those on the National DNA Database (NDNAD) who were profiled when under 18, regardless of their age now. Table 2 shows the number who are currently under 18. Table 3 shows the number of those who were under 18 at the time they were profiled, but are now over 18. In each case the figures are broken down by sex. 'Unassigned' means that the arresting officer did not complete the section of the form referring to the person's sex. The figures provided are for English and Welsh police forces only, and provide a snapshot of the NDNAD at 14 August 2008.

The number of profiles on the NDNAD is not the same as the number of individuals as a profile may be a replicate, that is, a profile may have been loaded on more than one occasion. This can occur if a person gives a different name, or different version of their name on separate arrests, or if a profile is upgraded. The current replication rate for the whole NDNAD is 13.3 per cent. The replication rate for various subsections of the NDNAD may differ from this so the figures for individuals are estimates.

The NDNAD does not hold information on criminal histories; this information is held on the Police National Computer (PNC). Information about the number of persons who were sampled when under 18 and have not been charged or cautioned with an offence could be obtained only at disproportionate cost.

To ask the Secretary of State for the Home Department how many (a) people and (b) people aged under 18 years were added to the national DNA database in each year since its inception. (201817)

The following table shows the number of subject profiles added to the National DNA Database (NDNAD) for English and Welsh police forces, and the number of these for people under the age of 18 years, in each year since its inception. It is not possible to add these figures to give the current position, as some profiles have been removed. The number of subject profiles held on the NDNAD is not the same as the number of individuals with a profile on the NDNAD. As it is possible for profiles from the same person 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, or because profiles are upgraded. The figures provided are for English and Welsh forces only.

To ask the Secretary of State for the Home Department how many people have their DNA profile stored on the national DNA database, broken down by (a) police force area and (b) ethnicity. (212371)

The number of subject profiles held on the National DNA Database (NDNAD) by force in England and Wales, as at 30 June 2008, is shown in Table 1.

The number of profiles is not the same as the number of individuals. This is because a number of subject profiles on the NDNAD are replicates, that is, a profile for a person has been loaded to the NDNAD on more than one occasion. This may arise for a number of reasons, such as a person giving a different name on different occasions they are arrested, or because of the upgrading of profiles from the SGM to the SGM Plus profiling system. It is estimated that at 30 June 2008,13.3 per cent. of the subject profiles held on the entire NDNAD were replicates.

However, this rate may vary between police forces, so figures for the number of individuals on the NDNAD are not given for each force.

The numbers of subject profiles, and individuals, on the NDNAD held by English and Welsh forces as at 16 July 2008, broken down by ethnic appearance, is shown in Table 2. Ethnic appearance is based on the judgment of the police officer taking the sample as to which of six broad ethnic appearance categories the person is considered to belong to. 'Unknown' means that no ethnic appearance information was recorded by the officer taking the sample.
