Children as young as 11 were among the 422 youngsters hauled in front of the courts and convicted last year in Northern Ireland.
Justice Minister Naomi Long revealed the shocking range of crimes children have committed in recent years - including robbery, violence against the person, fraud, motoring and drugs offences.
In some cases children aged 13 and under have been convicted of sex crimes.
More than 6,300 young people aged 16 and under have been convicted at court here since 2010. In 411 cases, the child was 13 and under.
However, the number of young people convicted each year has dropped significantly over the last decade.
In 2010, 931 children aged 16 and under appeared in court and were convicted of a crime but this fell to 422 in 2019 - a 55% reduction.
At the same time, there was also a drastic decrease in the number of children dealt with by way of out of court disposals, which include warnings, cautions and community based restorative justice.
In 2010, the youth diversion disposal methods were implemented as an alternative to court proceedings with 2,134 children aged between 10 and 16.
This fell to 764 in 2019 - a 64% reduction.
Ms Long released the information in response to an Assembly question from Green Party MLA Rachel Woods.
Explaining the drop in the number of child convictions and children receiving out of court disposals, Ms Long said: "Much of this is due to the commitment of my Department and criminal justice partners to early intervention and targeted support for children at risk of offending, with the aim of keeping them out of the formal justice system as far as possible whilst addressing their underlying needs."
A PSNI source said: "If a child of 10 or 11 is appearing in court, it's either for a very serious offence or they are a very persistent offender.
"If you can avoid putting a child into the system, then that's what you'll do because once they're in the system, that tends to be it.
"If you get them early enough, children can be diverted but it requires a lot more than the police, you need the home, social services and the education system to get on board."
The figures provided by Ms Long are broken down by age and offence category.
They include defendants aged between 10 and 13, 14, 15 and 16 from 2010 to 2019. The statistics do not provide a full account of the number of children who have appeared in court or been dealt with by the justice system as specific figures have only been provided where five or more children fall into a category.
Numbers where there are less than five children have been withheld in order to ensure no-one is identified. The figures also relate only to the main offence, so a child may have been dealt with for a number of offences but these have not been recorded.
They have shown that 1,623 children between 10 and 16 were convicted of violence against the person offences between 2010 and 2019, while 1,546 children were convicted of criminal damage over the same period.
Meanwhile, more than 700 children between 10 and 16 appeared in court and were convicted of a public order offence over the 10-year period.
The figure is likely to be so high given the number of children who become involved in rioting and attacking police during periods of unrest across Northern Ireland. In 411 cases the child was aged between 10 and 13. In 2019, children in this age bracket were convicted of crimes such as violence against the person, burglary and criminal damage.
The age of criminal responsibility - when a child is considered capable of committing a crime and old enough to stand trial and be convicted of an offence - is currently set at 10 in Northern Ireland, England and Wales.
The age of criminal prosecution in Scotland was raised to 12 back in 2011, meaning that younger children would be sent to children's hearings instead of court.
