To ask the Secretary of State for the Home Department what his estimate is of the proportion of violent crimes in each of the last five years where (a) alcohol and (b) illegal drug use were involved. [98173]
Police-recorded crime statistics can not provide information on the proportion of violent crime where alcohol and/or illegal drug use are involved. The British Crime Survey (BCS) reports on the victim's perception of offenders in violent incidents. Violent crime measured by the BCS can be classified into four sub-groups: domestic, mugging, stranger and acquaintance violence. The following tables show the proportion of violent incidents in which victims felt that the offender/s was under the influence of drink or drugs, firstly for all violence reported to the survey and then separately for the breakdown by individual types of violence. It should be noted that sweeps of the BCS were not conducted in 1997 or 1999.
