That is the second sentence in this short essay in The Atlantic. Here is an excerpt:

In Haiti … human trafficking is a problem at the best of times. Even without the pandemonium unleashed by a 7.0 earthquake, an estimated quarter-million Haitian children are trafficked within the country each year. These slaves, known as restavecs, are typically sold or given away to new families by their own impoverished parents. Physical and sexual abuse is common for restavecs. Many owners use the girls as in-house prostitutes, sending them to live on the street if they become pregnant.

Not all of these trafficked children end up as domestic slaves within Haiti:plenty of others are promised work in the Dominican Republic but are instead sold to work in agricultural fields or brothels across the border. Poor children who escape a life in bondage most often end up in street gangs; if they are fortunate, they may be accepted into overcrowded orphanages.
