The restavek system is tolerated in Haitian culture, but not considered to be preferable[citation needed]. The practice meets formal international definitions of modern day slavery and child trafficking, and is believed to affect an estimated 300,000 Haitian children.[3] The number of child domestic workers in Haiti, defined as 1) living away from parents' home; 2) not following normal progression in education; and 3) working more than other children, is more than 400,000. 25% of Haitian children age 5–17 live away from their biological parents.[4]
