"Among male state prisoners, violent (47%) and property (48%) offenders were less likely to report having children than public-order (60%) and drug (59%) offenders (table 6). For women held in state prison, violent (57%) offenders were less likely than drug (63%), property (65%), and public-order (65%) offenders to be a mother.
"The prevalence of being a parent differed by gender and offense for inmates held in state and federal prisons. For state inmates, female (65%) property offenders were more likely to be a parent than male (48%) property offenders. In federal prison, male (69%) drug offenders were more likely than female (55%) drug offenders to report having children.
"Among men held in federal prison, drug offenders (69%) were more likely than property (54%) and violent (50%) offenders to report having children (appendix table 5). Public-order offenders (62%) were also more likely than violent offenders to report having children. For women in federal prison, the likelihood of being a mother did not differ by offense."
