Cases of child sexual abuse by Catholic priests, nuns and members of religious orders, and subsequent cover-ups, in the 20th and 21st centuries have led to many allegations, investigations, trials and convictions. The abused include boys and girls, some as young as 3 years old, with the majority between the ages of 11 and 14. The accusations began to receive isolated, sporadic publicity from the late 1980s. Many of these involved cases in which a figure was accused of decades of abuse; such allegations were frequently made by adults or older youths years after the abuse occurred. Cases have also been brought against members of the Catholic hierarchy who covered up sex abuse allegations and moved abusive priests to other parishes, where abuse continued.
