Genetics: Databases

Volume 480: debated on Tuesday 7 October 2008

To ask the Secretary of State for the Home Department how many and what proportion of DNA samples were removed and destroyed from the National DNA database following a request to do so from the person from whom the DNA was taken in each year since the National DNA database has been operating, broken down by police authority area; and if she will make a statement. (197286)

The number of DNA profiles produced from samples taken from individuals by police forces in England and Wales which have been removed, for all reasons, since 2002-03, and the number of profiles held on the National DNA database (NDNAD) (for England and Wales police forces) at the end of each year, are shown in table 1. Removals broken down by police force are shown in table 2.

Information is not available breaking down removals into the number resulting from requests from the person from whom the DNA sample was taken, and the number resulting from other reasons. Details of removals before 2002-03 are not available because the NDNAD does not retain historic information; in 2002, an NDNAD management information database was created, which captures details of all record ‘transactions’, including the removal of records, and enabled the collection of this information from this point. As some profiles are duplicates, the number of profiles and the number of individuals these represent are not the same.

To ask the Secretary of State for the Home Department in how many violent offence cases in (a) Leeds West constituency, (b) Leeds metropolitan district and (c) Yorkshire and Humberside the national DNA database was used to match suspects in each year since figures are available. (213354)

Information on the National DNA database (NDNAD) is recorded and held on the basis of the police force which took the DNA sample. It is not available by parliamentary constituency or by local government authority area.

The table gives details of the number of violent offences in which a crime scene sample profile has matched with one or more subject profiles in each of the years since the 2002-03 financial year, for Humberside police, North Yorkshire police, South Yorkshire police and West Yorkshire police. Figures are not available for the years prior to 2002.

‘Violent offences’ cover the offences murder/manslaughter, attempted murder, other suspicious death, wounding and less serious assault.

Note:

Some of the offence codes used on the NDNAD cover more than one of the recorded crime classifications e.g. murder/manslaughter.

To ask the Secretary of State for the Home Department what proportion of the prison population in England and Wales has a profile on the national DNA database. (219355)

The purpose of the National DNA database (NDNAD) is to match DNA profiles taken from individuals with those taken from crime scenes. It therefore holds only the information necessary for this function, and does not contain criminal records or information on whether those on it are in prison. There are, however, good reasons for believing that the great majority of the prison population has a profile on the NDNAD. Police forces have had the power to retain DNA taken from those convicted of recordable offences since the establishment of the DNA database in 1995. For the first few years this power was exercised in relation to more serious offenders, but from 2000 onwards additional funding was made available under the DNA Expansion Programme to make it standard practice to take samples from all offenders. Since the extension of powers to take DNA samples to all those arrested for recordable offences, taking a DNA sample in the custody suite has become routine procedure. In addition, two prisoner sampling projects have been undertaken, most recently in 2003, to take DNA from any prisoner who had not already been sampled, for example because they had been imprisoned before DNA sampling was widely practiced.

To ask the Secretary of State for the Home Department pursuant to the answer of 8 January 2008, Official Report, column 454W, on genetics: databases, how many people have had their DNA profile removed from the national DNA database since January 2008. (220917)

Between 1 January and 31 August 2008, 148 subject profile records were deleted from the NDNAD under the exceptional case procedure (i.e. following a request to the chief officer of the responsible force from the person concerned). This covers records loaded by English and Welsh forces only.

To ask the Secretary of State for the Home Department (1) how many (a) children and (b) adults resident in the non-metropolitan county of Hampshire had their DNA recorded on police files in each of the last five years, broken down by local authority area; (222293)

(2) how many (a) children and (b) adults resident in Southampton had their DNA recorded on police files in each of the last five years.

Information held on the National DNA database (NDNAD) is available on the basis of the police force which added the DNA profile, not the address of the person sampled. Information is, therefore, not available on the number of residents of Southampton and the different local authorities in non-metropolitan Hampshire who have had a DNA profile added. Information is, however, available on the number of profiles added by Hampshire constabulary in the last five years, as shown in the following table. These do not necessarily relate to residents of Hampshire.

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 upgrading of profiles from the SGM to the SGM Plus profiling system. It is estimated that 13.3 per cent. of the subject profiles held on the entire NDNAD are replicates. However, this rate may vary between police forces, so figures for the number of individuals are not given for particular forces.

To ask the Secretary of State for the Home Department (1) how many people had DNA samples stored on the National DNA database at the most recent date for which figures are available; (222730)

(2) how many people had a DNA profile on the National DNA database in each of the last 12 months, broken down by (a) sex and (b) ethnic origin.

As at 17 September 2008, there were 4,991,871 subject profiles retained on the National DNA database (NDNAD) which had been added by English and Welsh police forces, which equates to an estimated 4,327,952 individuals. 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 upgrading of profiles.

Table 1 shows the number of subject profiles loaded to the NDNAD by English and Welsh police forces in each of the last 12 months, broken down by gender. ‘Unassigned’ means that no gender was recorded by the police officer who took the sample.

Table 2 shows the number of subject profiles loaded to the NDNAD by English and Welsh police forces in each of the last 12 months, broken down by ethnic appearance. 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. ‘Unknown’ means that no ethnic appearance was recorded by the officer taking the sample.

To ask the Secretary of State for the Home Department how many people of each (a) ethnicity, (b) age group and (c) sex in each ward of Greater Manchester have a DNA sample stored in the national DNA database. (223773)

Information held on the National DNA database (NDNAD) is available on the basis of the police force which added the DNA profile, not the address of the person sampled. Information is, therefore, not available on the number of people in each ward of Greater Manchester who have had a DNA profile added. Information is, however, available on the number of profiles added by Greater Manchester Police (GMP). These do not necessarily relate to residents of Greater Manchester. Tables 1-3 give figures for subject profiles on the NDNAD added by GMP, as at 17 September 2008, broken down by age, ethnic appearance and gender.

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 upgrading of profiles. It is estimated that 13.3 per cent. of the subject profiles held on the entire NDNAD are replicates. However, this rate may vary between police forces, so figures for the number of individuals are not given for particular forces.

Table 1 shows the number of subject profiles loaded to the NDNAD by GMP, broken down by ethnic appearance. 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. 'Unknown' means that no ethnic appearance was recorded by the officer taking the sample.

Table 2 shows the number of such subject profiles broken down by current age, not the age when sampled.

Table 3 shows the number of such subject profiles broken down by gender. 'Unassigned' means that no gender was recorded by the police officer who took the sample.
