The Crime and Victimisation Survey is a household survey about crime in Ireland carried out by the Central Statistics Office (CSO). Crime and Victimisation 2019 was part of the Health and Crime Survey, conducted via the CSO's General Household Survey (GHS) during Q2 and Q3 2019. Interviews took place during a six month interviewing period between April and October 2019. Previous Crime and Victimisation surveys have been carried out by the CSO in 1998, 2003, 2006, 2010 and 2015.

Respondents aged 18 years and over were asked to consider the period of 12 months prior to interview and to rate their response to a series of questions relating to the impact that crime has on their lives and their opinions on how effectively crime is dealt with in Ireland.

Respondents were then asked about their own personal experiences and the experiences of their household in terms of whether they had been the victim of different types of crime such as theft, assault or burglary in the 12 months prior to interview. Respondents who had experienced crime were asked additional questions, such as whether they had reported the crime to An Garda Síochána, reasons for not reporting if they didn't report, whether they felt the crime had been motivated by discrimination, and other contextual details relating to the crime.

The survey did not ask directly about sexual crimes as these are to be the focus of a comprehensive, dedicated national survey on sexual violence which is currently being developed by the CSO. However, it could be the case that victims of sexual assault may have reported on this as a physical assault in response to this survey.
