DNA: Databases

Question
To ask the Secretary of State for the Home Department how many new profiles have been added to the national DNA database by each police force in each month since 8 July 2009; and if he will make a statement.
Answer

The figures in table 1 show the number of subject profiles added to the National DNA Database (NDNAD) by English and Welsh forces and the British Transport Police in each month between 9 July 2009 and 15 October 2009, broken down by the police force which took the sample.The figures in table 2 show the number of crime scene profiles added to the NDNAD by English and Welsh forces and the British Transport Police in each month between 9 July 2009 and 15 October 2009, broken down by the police force which collected the sample.The number of subject profiles held on the NDNAD is not the same as the number of individuals. 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 currently estimated that 13.8 per cent. of subject profiles held on the NDNAD are replicates. The replication rate of 13.8 per cent. should only be applied over the entire database however, as the replication rate for individual police forces varies considerably. The presence of these replicate profiles on the NDNAD does not impact on the effectiveness and integrity of the database.
