In rare cases, a free agent is included only if that player later signs with an NFL team.The data comes from media reports and public records.It cannot be considered fully complete because records of some player arrests might not have been found for various reasons, including lack of media coverage or accessible public records.

According to a 2004 research study by the John Jay College of Criminal Justice for the United States Conference of Catholic Bishops, 4,392 Catholic priests and deacons in active ministry between 19 have been plausibly (neither withdrawn nor disproven) accused by 10,667 individuals of the sexual abuse of a youth under the age of 18.

Estimating the number of priests and deacons active in the same period at 110,000, the report concluded that approximately 4% have faced these allegations.

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 numerous 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.

Members of the Church's hierarchy have argued that media coverage was excessive and disproportionate, and they have also argued that such abuse also takes place in other religions and institutions.

A critical investigation by The Boston Globe in 2002 led to widespread media coverage of the issue in the United States, which was later dramatized in Tom Mc Carthy's film Spotlight in 2015.

For this reason there is insufficient data to be able to accurately ascertain current rates of child sex abuse, or to claim that abuse in the Catholic Church has fallen in recent decades.

The Commission revealed 7% of Australian priests between 1950–2009 were accused of abusing children, and that one Catholic order had 40.4% of their non-ordained members with allegations against them in this period.

This may be due in part to the more hierarchical structure of the Church in Third World countries, the "psychological health" of clergy in those regions, and because Third World media, legal systems and public culture are not as apt to thoroughly discuss sexual abuse.
