Question
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) 21 and over in each ethnic appearance category were registered on the national DNA database in each of the last five years; and how many of those had been (i) arrested but had no further action taken against them, (ii) charged but later acquitted, (iii) charged where such charges were subsequently dropped and (iv) given a reprimand of final warning in each of those years.
Answer

The function of the National DNA Database (NDNAD) is to match DNA profiles taken from crime scenes with those taken from individuals. It does not contain any information on whether those on it have been arrested, charged or given a reprimand or final warning.Information is available on the number of those whose profiles have been added to the NDNAD by English and Welsh police forces, as at 16 July 2008, broken down by ethnic appearance category and the age groups requested, as given in Table 1. 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 judgement 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 information was recorded by the officer taking the sample.
