the 2005–06 school year, and girls' enrollment was lower than boys'. Approximately 11 percent of students attended private Arabic-language schools, or "medersas", most of which taught core subjects including math, science, and foreign languages. An unknown number of primary school-aged children throughout the country attended part-time Koranic schools teaching only the Koran. These schools are partially funded by students, who are required to beg for money. The government provided subsidized medical care to children as well as adults, but the care was limited in quality and availability. Boys and girls had equal access to medical care. Statistics on child abuse were unreliable, and reported cases of abuse were rare, according to local human rights organizations. The social services department investigated and intervened in cases of child abuse or neglect. Most cases of sexual exploitation go unreported, and a government study recommended that the country strengthen its laws to protect children.

Women may legally marry at age 18 (or at age 15 with parental consent) and men at age 21. Underage marriage was a problem throughout the country with parents in some cases arranging marriages for girls as young as nine.

The victims were usually from the central regions of the country and not a specific ethnic group. Women and girls were trafficked from Nigeria for sexual exploitation, mainly by Nigerian traffickers. The law prohibits the contractual use of persons without their consent. Penalties increase if a minor is involved and range from five to 20 years' imprisonment. Although legal protections and measures are in place, parents of child victims were reluctant to file charges, and cases often languished within the justice system. During the year there also were reports of trafficking in persons between Mali and its neighbors, primarily Guinea, Burkina Faso, and Côte d'Ivoire. For example, in March security forces in Sikasso arrested two Ivorian nationals for trafficking 34 boys from Côte d'Ivoire, ranging in
