According to the Office to Monitor and Combat Trafficking in Persons, issues of human trafficking in Russia predominantly center around labor trafficking. This is due, in part, to the increase of labor migration to Russia. This labor migration has been on such a large scale that in a 2013 official statistics report there were approximately 1.1 million labor migrants reported in Moscow alone. Because of this, as well as the number of sexual exploitation cases, Russia has become an international source, transit, and destination for global human trafficking.
