Yes. It is estimated that the women in pornography are three times likelier to have been sexually abused as children than in the general population. Based on one survey of performers in the pornography industry, 37% of the women were raped as children.
Additionally, it is worth noting that women in the pornography industry are twice as likely to have grown up poor than in the general population. As research has proven that financial destitution significantly increases the likelihood of being subjected to sexual exploitation, it is no surprise that perpetrators of sexual violence, including pornographers and pimps, frequently target economically vulnerable women and children (and sometimes men).
