Slaves that made it to Haiti from the trans-Atlantic journey and slaves born in Haiti were first documented in Haiti's archives and transferred to France's Ministry of Defense and the Ministry of Foreign Affairs. As of 2015[update], these records are in The National Archives of France. According to the 1788 Census, Haiti's population consisted of nearly 40,000 whites, 30,000 free coloureds and 450,000 slaves.
In Mauritania, the last country to abolish slavery (in 1981), it is estimated that 20% of its 3 million population, are enslaved as bonded labourers. Slavery in Mauritania was criminalized in August 2007. However, although slavery, as a practice, was legally banned in 1981, it was not a crime to own a slave until 2007. Although many slaves have escaped or have been freed since 2007, as of 2012[update], only one slave owner had been sentenced to serve time in prison.
