The BCS 2000 included over 19000 respondents and the 2001 survey includes around 40,000 respondents.
Respondents are asked a series of screening questions to establish whether or not they had been the victims of crime during the reference period, and a series of very detailed questions about the incidents they reported. Basic descriptive background information on the respondents and their households was also collected to allow analysis of the sorts of people who do and do not become victims. Other information collected was on fear of crime, contact with the police, lifestyle, self-reported offending and attitudes to the Criminal Justice System, including the police and the courts.
Some years contain self-completion drugs, domestic violence, sexual victimisation or stalking files. Due to their sensitive nature, data on sexual victimisation (1994, 1998 and 2000) are currently unavailable, though it is hoped they may be deposited at UK Data Archive in the future.
Most years include an ethnic booster sample of black and Asian adults.
