Study to prepare summary profiles of four groups (Māori boys, Māori girls, non-Māori boys, and non-Māori girls) appearing in the Children’s Court from April 1959 to March 1960. The data was taken from Child Welfare Punch Cards which are derived from Case Reports and the sample included all children between the ages of 10 and 17 involved in Children’s Court cases from April 1959 to March 1960, excluding technical and minor traffic offences. The profiles created for each of the four groups detail average age, education, employment history, family situation and locality, previous notice, present offences, and the outcome of their court appearance. These profiles show that in areas where non-Māori delinquent children are ‘handicapped’, the Māori children are handicapped more frequently and probably more severely (e.g higher incidences of ‘broken homes’ and unsatisfactory schooling). Māori children were also more likely to come from ‘larger’ families, have one or both parents deceased, be ‘more retarded academically’, have committed offences of dishontest, be unemployed (if left school), and receive harsher sentences. Māori children were less likely to be living with their ‘natural’ parents. These differences between offenders were concluded to likely represent the wider population in general.
