Genetics: Databases

Volume 487: debated on Wednesday 4 February 2009

To ask the Secretary of State for the Home Department with reference to the answer of 15 September 2008, Official Report, columns 2069-70W, on genetics: databases, what her most recent estimate is of the number of DNA samples taken and loaded onto the national DNA database since 31 March 2008 which would not previously have been taken prior to the entry into force of the Criminal Justice and Police Act 2001; and if she will make a statement. (251165)

The National DNA Database is designed to match DNA taken from crime scenes with that taken from individuals. It does not hold information on whether those with records on it have convictions, as this is not necessary for this purpose. Some data on whether those on the NDNAD have convictions is available from the police national computer (PNC), but not as part of its routine functions and not within the cost limit for parliamentary questions. However, the National Policing Improvement Agency does obtain this information periodically and this was last done at the end of March 2008. The information is due to be obtained again at the end of March 2009.

To ask the Secretary of State for the Home Department (1) how many new profiles have been added to the national DNA database since December 2008, broken down by age group; how many have been added by each police force; and if she will make a statement; (251184)

(2) with reference to the answer of 5 March 2008, Official Report, columns 2669-70W, on genetics: databases, how many and what proportion of new DNA profiles added to the national DNA database in each month since 18 January 2008 relate to individuals aged (a) under 16, (b) 16 to 18, (c) 19 to 20, (d) 21 to 30, (e) 31 to 40, (f) 41 to 50, (g) 51 to 60 and (h) over 60 years, broken down by police force responsible for the profile being added; and if she will make a statement.

The figures given in Table 1 show the number of profiles added to the National DNA Database by English and Welsh forces during the period 1 to 22 January 2009, broken down by age group and the police force which added the profile.

The figures given in Table 2 show the number of profiles added to the National DNA Database by English and Welsh forces during the period 18 January to 31 December 2008, broken down by age group and the police force which added the profile. It is not possible to break this information down by month except at disproportionate cost.

The age breakdown in both tables is based on the age of the subjects as at 22 January 2009. The figures show the number of profiles added to the database. Some of these may since have been deleted.

A proportion of DNA profiles held on the NDNAD are replicates, that is, a profile for a person has been loaded on more then one occasion (this may be because the person gave different names, or different versions of their name, on separate arrests, or because of upgrading of profiles). It is estimated that 13.3 per cent. of profiles held on the NDNAD are replicates. Therefore, the number of individuals on the NDNAD is approximately 13.3 per cent. less than the number of subject profiles. The presence of these replicate profiles on the NDNAD does not impact on the effectiveness and integrity of the database.

To ask the Secretary of State for the Home Department what her most recent assessment is of the contribution made by the national DNA database to the detection of crime; and if she will make a statement. (252550)

The National DNA database is a key police information tool which contributes to the efficiency of crime detection. It has a key role to play in contributing to detection outcomes, eliminating the innocent from inquiries, focusing the direction of inquiries resulting in savings in police time and in building public confidence that elusive offenders may be detected and brought to justice.

It is estimated that over the period April 1998 to end September 2008, there have been approximately 290,000 detections in which a DNA match was available or played a part in solving the crime. A breakdown of this figure by year is given in the following table. It includes figures for quarters 1 and 2 of 2008-09 to 30 September 2008.
