An inquiry examining institutional sex abuse in Australia has heard 7% of the nation's Catholic priests allegedly abused children between 1950 and 2010. In one religious order, over 40% of church figures were accused of abuse.

The full scale of the problem emerged on Monday, when the commission released the statistics it has gathered. Gail Furness, the lead lawyer assisting the commission in Sydney, said more than 1,000 Catholic institutions across Australia were identified in claims of sexual abuse, with a total of 1,880 alleged perpetrators between 1980 and 2015. The average age of the victims was 10.5 for girls and 11.5 for boys. On average, it took 33 years for each instance of abuse to be reported.

I think it would be worth digging into these institutions outside of Australia...
