The recidivism rate reduces with age, according to new Central Statistics Office (CSO) probation figures.
For the 2013 probationers, 73.6% of offenders under 18 re-offended within three years, compared with 27.5% of those aged 45-64.
Reoffending rates, overall, are also decreasing slowly.
A total of 28% of probationers in 2013 reoffended within one year, down from a total of almost 36% of probationers in 2008 who did so.
The CSO report shows that re-offending by those sentenced to probation supervision in 2013 was 45.3%, compared with 54.6% in the 2008 cohort.
Males are more likely to reoffend than females (45.9% for males compared with 41% for females for the 2013 cohort across a three-year period), but the gap between them is decreasing.
The majority of those sentenced to probation do not reoffend within three years of their sentence.
Close to three-in-ten offenders managed by the Probation Service reoffend within one year; and four in ten reoffend within two years.
There is considerable geographical variation in the level of reoffending.
Data for the 2015 cohort shows that 16.7% of individuals with a Mayo address reoffend within one year, compared with almost half (49.1%) of individuals with an address in Westmeath.
Those with a burglary conviction are more likely to commit more offences, while sexual offenders are least likely to do so.
The report also shows variations, depending on whether the individual was sentenced to a community-service order, a probation order or post-custody supervision.
Overall, those sentenced to a community-service order were less likely to reoffend than those sentenced to a probation order (41.6% compared with 49.6% for the 2013 cohort over a three-year period).
Justice minister Charlie Flanagan said that the Criminal Justice (Burglary of Dwellings) Act 2015 was enacted as a response to repeat offending, and targets repeat burglary offenders through bail measures, and providing for consecutive sentencing for repeat offending.
