The John Jay report indicated that some 11,000 allegations had been made against 4,392 priests in the USA. This number constituted approximately 4% of the 110,000 priests who had served during the period covered by the survey (1950-2002).[39] The report found that, over the 52-year period covered by the study, "the problem was indeed widespread and affected more than 95% of the dioceses and approximately 60% of religious communities."
In 2008, the Church asserted that the scandal was a very serious problem but, at the same time, estimated that it was "probably caused by 'no more than 1 per cent' (or 5,000) of the over 500,000 Roman Catholic priests worldwide.
