EL SALVADOR. Intipuca, La Union. 26 September, 2018. Framed photographs of family members living in the United Sates are hanged on the wall of Catalina Silva de Medina, a resident of Intipuca. Some 5.3 million Central American immigrants live in the United States, 2.9 million of them from El Salvador, a country of just 6.3 million people whose recent history has been blighted by civil war, gang violence, and economic struggles.
