A 2003 study on commercial sex exploitation of children, carried out by Hope Case Foundation and Uganda Youth Development Link, reveals that child commercial sex is on the increase worldwide, with about 1.8 million children being exploited. In Uganda, many students and school dropouts engaged in commercial sex. A study conducted in the districts of Mbale, Busia, Kabarole and Lira shows that, of the 728 children (90.3% of these girls and 9.3% boys) interviewed, only 35% still go to school while 70% of the children don't stay with their parents. Of the 728, 95% are paid money for sex, 16% get food, while 11% get free entry to discotheques as payment for sex.
