Lifting of Under Reservation Categorisation

Following the publication of the fifth Review of the Quality of Crime Statistics in October 2023, the Central Statistics Office (CSO) has lifted the 'Under Reservation' categorisation around Recorded Crime Statistics. This is possible because An Garda Síochána have introduced a range of quality measures over the last number of years which have resulted in sustained improvement in the quality of the underlying crime data. These changes give a level of assurance to users that they can rely on Recorded Crime Statistics.

For further information see our Lifting of Under Reservation categorisation for Recorded Crime Statistics FAQ page.

Introduction

This publication provides figures for the re-offending rates of those placed on Probation, Community Service and Post Release Supervision Orders in the year 2019.

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. Due to timing issues in respect to the extraction of data, figures may be revised after this publication.

Data collection

These figures were produced using a combination of An Garda Síochána and Probation Service records. Since there is no direct link between the two systems, a statistical matching protocol was devised by the CSO to match Probation 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.

Due to the absence of a unique identifier in the Irish Criminal Justice system the matching process involves the comparison of individual records. It is not possible to find a match for all Probation records in the Garda PULSE dataset. This may be the case because of data quality issues, because the subjects name is a common one or because the subject provided incorrect details to law enforcement officials.

CSO guidelines state a minimum of 95% of records must be matched. CSO guidelines state a minimum of 95% of records must be matched. In the 2017 and 2018 cohort 100% of records were matched. 

In the region of 95% of all matches used in the publication are matched automatically. That is, the name, address and date of the birth details for the subject in the Probation 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 5% 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.

Re-offending

For this report there are two conditions which must be met in order for an individual to be classified as a re-offender:

  1. The individual must commit a recorded incident within a defined period of the date of their Probation Order. The length of the period considered varies for different cohorts. The period is 1 year for the 2019 cohort.
  2. There must be a conviction for this incident within two years of the date on which the incident was recorded.

For example, if a person was placed on a Probation or Community Service Order on December 31st, 2019 and committed an offence on the December 31st, 2020, they would be considered as having re-offended if court proceedings leading to a conviction were concluded on or before December 31st, 2022.

Exclusions

When considering re-offending, certain offence types were historically excluded. These offences were mainly traffic offences and some animal welfare offences. For re-offending analysis from 2017 onwards (both prison and probation re-offending) all offences resulting with a court conviction are classified as a re-offending offence for the purpose of measuring re-offending.

Probation type

This report considers three types of probation: Probation Orders, Community Service Orders and Post Release Supervision Orders.

Removal of the ‘Statistics Under Reservation’ designation from Probation Re-Offending Statistics

The CSO published its fifth CSO Review of the Quality of Recorded Crime Statistics in October 2023. As part of this review the CSO has lifted the ‘Under Reservation’ designation  from all Recorded Crime data disseminated after Quarter 1 (Q1) 2023.

CSO has made this decision because the terms of its various key recommendations from the Quality Improvement Proposal from 2018 and Quality Reviews have been met, principally:

  • The development and implementation of a formal data quality management system for PULSE that ensures fit-for-purpose crime data (developments throughout 2022 & 2023 culminating in quality checking and publishing of those results, with a focus on risk management).
  • An independent review conducted on behalf of AGS which found evidence of good controls for the acknowledged risks to data collection and quality.
  • There is now a senior manager (appointed in 2019) within AGS who has overall responsibility for data quality.
  • The provision of a comprehensive and publicly available document explaining how crime is recorded (2020).

In addition, a new Memorandum of Understanding has been agreed between CSO and AGS which explicitly outlines expectations concerning AGS quality checking and reporting of same. The standard quality checks of PULSE data carried out as part of this fifth CSO Quality Review show evidence of consistent high data quality levels.

AGS has worked over the past number of years to advance the assurance levels which can be provided around Garda PULSE data, and in particular the quality management developments of 2022 and 2023. This work has seen the development of quality assurance processes by AGS over the period which has culminated in the implementation of a more formal data quality management system by AGS.

The recorded crime series has been progressively improving over time with the cumulative impact of the improved data quality, assessment, and assurance measures being seen in a higher data quality level as noted in various CSO reviews in recent years.

Given the new AGS controls for quality checking and reporting, coupled with the CSO reserving the right to do its own reviews, a level of assurance has been provided warranting the lifting of the "Under Reservation” categorisation. 

However, some judgement should be exercised by users when using data produced in the earlier years of the recorded crime time series given the legacy quality issues which have been commented on in various reviews. For instance, detections data pre and post 2018 are not comparable given the improved governance controls introduced in that year. The CSO will continue to inform users of the quality of the data they are using, and of any particular issues which may need to be noted around time series comparability as they arise.

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 ICCS.

Custodial/Non-custodial court outcomes

For the purposes of showing re-offending sanctions in this publication, court outcomes have been classified to provide aggregate estimates of either a custodial or non-custodial reprimand. The outcomes in the table below have been classified for this purpose under either custodial or no-custodial sanction. In a small number of cases it is not currently possible to define the re-offending offence court outcome as custodial or non-custodial. For the purpose of this publication cases that are not classified have been excluded from the custodial / non-custodial estimates.

NUTS2 and NUTS3 Regions

The Nomenclature of Territorial Units for Statistics (NUTS) were created by Eurostat in order to define territorial units for the production of regional statistics across the European Union. In 2003 the NUTS classification was established within a legal framework (Regulation (EC) No 1059/2003).

As the administrative territorial breakdown of EU Member States is the basis of the NUTS classification, changes made under the 2014 Local Government Act prompted a revision to the Irish NUTS 2 and NUTS 3 Regions. These changes included the amalgamation of the local authorities of Tipperary North and South, Limerick City and County Councils and Waterford City and County Councils. In addition three Regional Assemblies were established (Northern & Western, Southern, Eastern & Midland).

The main changes at NUTS 3 level are the transfer of South Tipperary from the South-East into the Mid-West NUTS 3 region and the movement of Louth from the Border to the Mid-East NUTS 3 Region. There are now three NUTS 2 Regions which correspond to the Regional Assemblies established in the 2014 Local Government Act and are groupings of the new NUTS 3 Regions. The revisions made to the NUTS boundaries have been given legal status under Commission Regulation (EU) 2016/2066. The new NUTS 2 and NUTS 3 structure and classification are displayed in the table below:

Personal characteristics

CSO publish crime related statistics classified by the personal characteristics of persons linked to justice procedures. In the Probation Re-Offending publication these characteristics are based on data captured at the time of the justice sanction (probation order) being issued. These include:

  • Age categories (Years)
  • Gender/Sex categories (Male or Female)
  • Dwelling location (County or Region)
