The Conviction statistics: Minors is conducted by the National Institute for Statistics based on information deriving from the Central Register for Criminal Responsibility of Minors, which is owned by the Ministry of Justice. Its statistical exploitation is the result of the collaboration agreement signed in 2007 between both institutions, updated and renewed on November 21, 2017.

The fundamental objective of these statistics is the analysis of the social demographic characteristics of under-age persons (14 to 17 years old) that have been formally convicted over the course of the reference period. It also provides information about the criminal offences committed by under-age persons that have been convicted as well as the measures adopted. Since 2017, more detailed information on sexual offences is also offered.
