In recent months, migrants at the southern border have endured grim living conditions and forced deportations. A sobering study led by researchers at Mexico’s National Institute of Public Health and published in the academic journal PLOS ONE sheds light on what migrants go through to arrive at the border in the first place. The study is based on data collected between 2009 and 2015, when more than 12,000 migrants participated in a voluntary survey about their experiences with physical, psychological, and sexual violence during their transit through Mexico.
