Unpaid labor is still a practice in Haiti. As many as half a million children are unpaid domestic servants called restavek, who routinely suffer physical and sexual abuse. Additionally, human trafficking, including child trafficking is a significant problem in Haiti; trafficked people are brought into, out of, and through Haiti for forced labor, including sex trafficking. The groups most at risk include the poor, women, children, the homeless, and people migrating across the border with the Dominican Republic. The devastating earthquake in 2010 displaced many, rendering them homeless, isolated, and supremely vulnerable to exploitation by traffickers. The chaos following the quake also distracted authorities and hindered efforts to stop trafficking. The government has taken steps to prevent and stop trafficking, ratifying human rights conventions and enacting laws to protect the vulnerable, but enforcement remains difficult. The U.S. State Department's Office to Monitor and Combat Trafficking in Persons placed the country in "Tier 2 Watchlist" in 2017.
