In 2019, more than 50,000 children migrants seeking asylum from Central and South America were held in detention facilities. Mexico has just reversed this policy and will no longer hold them as detainees. Instead, the responsibilities for housing these children have been shifted to Mexico's family development agency. This is a big win that's being applauded by the UN. "Detaining children has an impact on their psycho-emotional development in the short, medium and long term," according to the International Detention Coalition and the Institute for Migrating Women.
