Answer

Data on the number of males whose profiles have been added to the National DNA Database (NDNAD) by English and Welsh police forces, as at 16 July 2008, broken down by sex and the age groups requested, is shown in table 1. Equivalent data for females is given in table 2. Age is defined as the person's age at the time DNA was taken from them, not their current age. This data could only be further broken down to show which profiles were added in each of the last five years at disproportionate cost.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.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 to. 'Unknown' means that no ethnic appearance information was recorded by the officer taking the sample.
