Mothers in Prison by Race/Ethnicity
"Almost half (48%) of all mothers held in the nation’s prisons at midyear 2007 were white, 28% were black, and 17% were Hispanic. Of the estimated 147,400 children with a mother in prison, about 45% had a white mother. A smaller percentage of the children had a black (30%) or Hispanic (19%) mother."
