The Impact of Sentencing on Offenders' Future Labour Market Outcomes and Re-offending - Community Work Versus Fines

Published 23 June 2015

Authors: Michele Morris and Charles Sullivan

Abstract

This study provides evidence to help inform sentencing policy by assessing the differential impact of two types of sentences (community work and fines) on adult offenders' subsequent employment, benefit receipt and re-offending. This is the first study in New Zealand to examine post-sentencing employment outcomes and benefit receipt of such offenders.

We focus on offences where we observe variation in sentencing after controlling for observable differences and examine outcomes for up to three years following conviction. This analysis uses recently-linked anonymised administrative data from the tax, benefit and justice systems within Statistics New Zealand's Integrated Data Infrastructure, which provides detailed information on all convicted offenders and their offending. Impacts are estimated by comparing the changes in post-conviction outcomes of offenders who received a fine with changes in outcomes for matched comparison groups of offenders who received a community work sentence. Matching is done using the method of propensity score matching. Impacts are estimated separately for four types of offences and for a general model that pools several types of offences together.

People sentenced to community work are more likely to re-offend within two years of conviction compared to fined offenders. There is no difference in impact on employment during the follow-up period for the two types of sentences (except in one case where there is a short-term differential impact in the year following conviction). We find that people sentenced to community work are more likely to be on benefit following conviction compared to people who are fined. We regard our estimates as an upper bound of the true differential impact of community work compared to fines on offenders' subsequent outcomes. While our method controls for observed offender characteristics, it is still possible that there are significant uncontrolled differences between the offenders who were sentenced to community work and those who were fined (eg, the differences in being on benefit could be due to differences in the level of financial support from a partner).

The results in this report are not official statistics - they have been created for research purposes from the Integrated Data Infrastructure (IDI) managed by Statistics New Zealand. On-going work within Statistics New Zealand to develop the IDI means it will not be possible to exactly reproduce the data presented here.

Access to the anonymised data used in this study was provided by Statistics New Zealand in accordance with security and confidentiality provisions of the Statistics Act 1975. Only people authorised by the Statistics Act 1975 are allowed to see data about a particular person, household, business or organisation. The results in this report have been confidentialised to protect these groups from identification.

Careful consideration has been given to the privacy, security and confidentiality issues associated with using administrative and survey data in the IDI. Further detail can be found in the Privacy impact assessment for the Integrated Data Infrastructure available from Statistics New Zealand.[1]

The results are based in part on tax data supplied by Inland Revenue to Statistics New Zealand under the Tax Administration Act 1994. This tax data must be used only for statistical purposes, and no individual information may be published or disclosed in any other form or provided to Inland Revenue for administrative or regulatory purposes.

Any person who has had access to the unit-record data has certified that they have been shown, have read and have understood section 81 of the Tax Administration Act 1994, which relates to secrecy. Any discussion of data limitations or weaknesses is in the context of using the IDI for statistical purposes and is not related to the data's ability to support Inland Revenue's core operational requirements.
