IntroductionThis paper presents an analysis of the data of the technical team (psychologist, social worker and educator) of the juvenile court of Toledo (Spain) from 2001 to 2012. MethodologyDescriptive study of the annual series of a sample of 3,333 juvenile offenders and their psychosocial, educational and criminal characteristics. ResultsIn the latter years of the series there tends to be infractions of greater gravity committed by older boys. ConclusionsJuvenile delinquency in the province of Toledo remained constant from 2001 until 2009, when a sharp increase was observed, which lowered again during the years 2011 and 2012. However, in the latter years of the series (starting 2008) an increase in the gravity of the acts is noted, with the number of crimes increasing more significantly than the misdemeanours. The team has also detected that perhaps institutions underestimate the diagnosis of the juvenile misdemeanours, even in mental health issues, such as abuse of alcohol and other substances. Therefore, these minors may not achieve the benefits of the justice youth system.
