Answer

The information requested is given in the table. The figures show the number of subject sample profiles retained on the National DNA Database (NDNAD) at 31 March 2008, which were taken by police forces in England and Wales. The number of subject profiles is not the same as the number of individuals. It is currently estimated that 13.3 per cent. of profiles held on the NDNAD are replicates, that is, that a profile for a person has been loaded on more than one occasion. The replication rate of 13.3 per cent. should, however, be applied only over the entire NDNAD, as the replication rate for individual police forces varies considerably. The table gives the number of subject profiles for each police force only, but gives a total estimated number of individuals for all English and Welsh police forces.
