According to a new U-M study, 4 in 10 children in the United States grow up in homes where a parent or residing adult is involved in the criminal justice system. Michael Mueller-Smith, assistant professor of economics and a faculty associate at the Institute for Social Research Population Studies Center, notes that the adult or parent has faced at least one criminal charge, was convicted of a felony or spent time in prison. The faculty expert further highlights the impact on future generations.
