For decades, the Catholic Church has dealt with the priest sex abuse crisis as allegations have surfaced worldwide.

The church has paid out more than $3 billion to settle sexual abuse claims, according to an analysis of BishopAccountability.org, an online database that tracks the sex abuse crisis.

More than 6,800 U.S. Catholic priests have been credibly accused of sexual abuse, according to an analysis by BishiopAccountability.org of U.S. Conference of Catholic Bishop data, and there are at least 19,000 survivors of sexual abuse by U.S. Catholic priests.

With the Archdiocese of Galveston-Houston and other Texas dioceses are expected to release lists of priests credibly accused of sexually abusing children today, here's a look back at the crisis.
