Offender surveys. These surveys are designed to take information from offenders, often those in prison, in order to develop an understanding of the behaviour and attitudes of offenders.By interviewing a range of young offenders looking back over the previous years, they identified specific trends in anti-social behaviour, namely a peak between the ages of 14 and 16, and the relationship between offending behaviour and the use of drugs or alcohol.This kind of data helps researchers to identify potential risk factors and develop ways to prevent a person from becoming an offender, for example through treatment programmes targeted at certain age groups.

To measure which gender commits more crime you can see the population of a prison and see how many inmates are women and men

Victim surveys. One of the largest victim surveys carried out in the UK is the Crime Survey for England and Wales (CSEW). It is a face-to-face survey which collects data from 50,000 households in the UK (2016/17), who are selected at random through a “postcode lottery”. This means that not all households will be interviewed and also participants have the right to withdraw or refuse to be interviewed. Adults and children are questioned on their experiences of crime
