asked Her Majesty's Government:

How many individuals' data are stored on the national fingerprint database; and, of those, how many (a) are convicted criminals; (b) are currently serving a sentence; (c) have not been convicted of a crime; and (d) have never been charged with a recordable offence. [HL1308]

The number of individuals with fingerprints stored on the national fingerprint database is 7,356,285. The database does not store details of convictions. Information relating to the conviction status of those on the database could be obtained only at disproportionate cost.
