A significant reduction in childhood poverty could cut criminal convictions by almost a quarter, according to a study conducted in Brazil. An article on the study is published in Scientific Reports. The researchers used an innovative approach involving an analysis of 22 risk factors that affect human development and interviews with 1,905 children at two points – a first interview to form a baseline (mean age 10.3) and a follow-up interview seven years later (mean age 17.8).
