Hey all, Was wondering if anyone knew the source for the pie chart @18:00 of this vid "Child Abuse & Neglect by Relationship to Victim" - i've looked through the links above but cannot find it.... Also, would be right in assuming that step-parents are included in the "parent" category - hence the differentiation with "unmarried partner of parent"...? Would really appreciate any help on this.
