Background Notes
Introduction
This publication provides figures for the re-offending rates of individuals released from prison in the year 2011 and 2012 (the 2011 and 2012 cohorts).
The term “offences” in this report refers to crime incidents known to An Garda Síochána and recorded as such in the Garda PULSE (Police Using Leading Systems Effectively) system. Because of timing issues with respect to the extraction of data, figures may be revised after this publication.
Data collection
These figures were produced using a combination of Garda Síochána and Prison records. Since there is no direct link between the two systems, a statistical matching protocol was devised by the CSO to match Prison and Garda records. This protocol was updated in 2019 to capitalise on technological improvements that have become available in the 5 years since the report was first published. This revised matching process was applied to the 2011 and 2012 cohorts and will be applied to all subsequent cohorts until further notice.
Due to the absence of a unique identifier in the Irish Criminal Justice system the matching process involves the comparison of individual records. In the region of 60% of all matches are matched automatically. That is, the name, address and date of the birth details for the subject in the Prison dataset corresponds exactly with those details in the Garda PULSE dataset.
Due to data quality issues and limitations on the reliability of some information provided to law enforcement authorities, the remaining 40% of matches require manual examination. There are clear guidelines in place in relation to the selection or rejection of matches, but a certain level of subjectivity is inevitable in the absence of a unique identifier.
Recidivism/Reoffending
For this report the individual must commit a recorded incident within three years of their release from prison.
Exclusions
When considering re-offending, certain offence types are excluded. These offences include mainly traffic offences and some animal welfare offences. A complete list is available on request.
Crime recording
Incidents reported, or which become known to members of An Garda Síochána, are recorded when, on the balance of probability, a Garda determines that a criminal offence defined by law has taken place, and there is no credible evidence to the contrary. If it is subsequently determined that a criminal incident did not take place, the record is invalidated and is not counted in the statistics. If a person makes a report and subsequently withdraws it, then this too is invalidated unless there is evidence to suggest that, by reasonable probability, the offence has taken place.
For criminal incidents where victim confirmation is required (e.g. assault, fraud), a criminal incident is recorded only where the victim confirms the incident or where there is evidence to suggest that by reasonable probability it occurred.
Crime Classification
A criminal incident is classified as a particular offence type at the initial recording of that incident. However, upon investigation, it may later become apparent that an alternative offence type should be used. In this event, the record is amended to reflect this. Re-classification based on court proceedings only occurs in relation to homicide offences. The classification is used in this publication is the ICCSq.
