DNA Database

Volume 455: debated on Thursday 25 January 2007

To ask the Secretary of State for the Home Department what percentage of the population have their details stored on the national DNA database, broken down by region. (115988)

The following table contains details of the individuals from each police force area, held on the National DNA Database as at 31 October 2006, grouped into ACPO regions. It should be noted that the Database shows which force took a DNA sample from the individual concerned, not which force area the person resides in.

Note:

The number of residents in each police force area is taken from the Police Almanac (2006). The figures from the database are those at 31 October 2006. The number of profiles shown for each force and region relates to the number of people sampled by each force, not the number of those sampled who live in the force area. This explains the figure for the City of London police – the force has a very small resident population and almost all those sampled live elsewhere. Previous statistics on the number of individuals on the Database were calculated on the basis that 11 per cent. of the profiles were replicates, i.e. the number of individuals was 11 per cent. less than the number of profiles. The Database has recently advised that the replication rate is now 13.7 per cent. so the figures have now been calculated on this basis.
