A five-year study in Australia, he says, supported his findings. And a comprehensive study by John Jay College of Criminal Justice, published in 2004, confirmed his original estimate of the percentage of American priests involved with minors. The study found, he says, that more than six percent of priests ordained between 1960 and 1984 were alleged to have had sex with children. A longer look, from 1950 to 2002, found 10,667 children allegedly victimized by 4,392 priests. Half of their victims were found to have been between 11 and 14 years of age; about 80 percent of them were male.
