DNA: Databases

Volume 493: debated on Monday 1 June 2009

To ask the Secretary of State for the Home Department how many foreign nationals of each nationality were listed on the national DNA database on 1 April 2009. (271356)

The National DNA Database (NDNAD) stores the absolute minimum amount of personal data, and does not store the nationality or the home addresses of subject profiles. Therefore we are unable to determine how many foreign nationals are on the NDNAD.

To ask the Secretary of State for the Home Department how many people aged (a) under 10, (b) 10 to 17, (c) 18 to 20 and (d) over 20 years old in each ethnic appearance category were registered on the national DNA database in each of the last five years; and how many of these had no conviction, caution, formal warning or reprimand recorded on the police national computer. (271981)

The following tables show how many profiles were added to the NDNAD by police forces in England and Wales in each of the last five years, broken down by age and ethnic appearance. The age groups refer to an individual's age on the date that their profile was loaded to the NDNAD, not their current age. The ethnic appearance categories refer to the ethnic appearance recorded by the police officer who took the sample. “Unknown” means that no age/ethnic appearance was recorded by the officer who took the sample.

In accordance with my announcement on 16 December 2008, all profiles of under 10s have now been deleted from the NDNAD.

The number of profiles is not the same as the number of individuals. This is because some profiles are replicates—i.e. more than one profile is held for one individual. This may occur if, for example, an individual gives different names, or different versions of their name, on separate arrests. The most recent estimate of the replication rate on the NDNAD is 13.5 per cent.

It is not possible to break the information in the tables down further into the number of people in each category who had no conviction, caution, formal warning or reprimand recorded on the Police National Computer (PNC). The NDNAD does not hold information on whether an individual has a conviction.
