Family size and delinquency.
A review of the literature shows that large family size is related to greater delinquency. The relationship remains when a number of variables, i.e., income, socioeconomic status, parental criminality, and family composition, have been controlled. The higher birth rate for lower classes does not appear to be an adequate explanation for this relationship, nor does less close parent-child affectional ties or less parental supervision although all of these may have some influence. The presence of an "infectious example" may partly account for the relationship, as does overcrowding. Large family size is typically associated with the constellation of undesirable family conditions involving poor role models (e.g., poor parental behaviour, parental criminality, sibling delinquency), poor child-rearing practices (e.g., inadequate parental supervision and discipline), and competition for physical (e.g., overcrowding, low income) and psychological (e.g., lack of attention, affection, family interaction) resources. An immediate solution is to reduce the size of families by helping prospective parents plan their families, and for those who wish it, making medical abortions more readily available. The long-range solution is through research to identify variables which significantly influence the relationship between family size and delinquency. Such studies must control for birth order, sibling spacing, siblings' sex, and sex of the delinquents in these families.
