"Mothers in state prison (58%) were more likely than fathers (49%) to report having a family member who had also been incarcerated (table 11). Parents in state prison most commonly reported a brother (34%), followed by a father (19%). Among mothers in state prison, 13% reported a sister and 8% reported a spouse. Six percent of fathers reported having a sister who had also been incarcerated; 2%, a spouse.

"While growing up, 40% of parents in state prison reported living in a household that received public assistance, 14% reported living in a foster home, agency, or institution at some time during their youth, and 43% reported living with both parents most of the time (appendix table 11). Mothers (17%) held in state prison were more likely than fathers (14%) to report living in a foster home, agency, or institution at some time during their youth. Parents in federal prison reported lower percentages of growing up in a household that received public assistance (31%) or living in a foster home, agency, or institution (7%). These characteristics varied little by gender for parents held in federal prison.

"More than a third (34%) of parents in state prison reported that during their youth, their parents or guardians had abused alcohol or drugs. Mothers in state prison (43%) were more likely than fathers (33%) to have had this experience. Fewer parents (27%) in federal prison reported having a parent or a guardian who had abused alcohol or drugs."
