 The surveys filtered information provided from diocesan files on each cleric accused of sexual abuse and on each of the clerics' victims to the research team so that they did not have access to the names of the accused clergy or the dioceses where they worked.The dioceses were encouraged to issue reports of their own based on the surveys that they had completed.Of the 4,392 clergy accused, 3,300 were not investigated because the cleric had already died.
