According to national estimations based on Census data, almost 370 000 foreign-born persons were living in Chile in 2010, which represents an increase of around 20 000 compared with the previous year and twice the number of immigrants registered in 2002. Most immigrants in Chile are from other South American countries, with 61% from neighbouring countries. Over the past few years, Peru has replaced Argentina as the main country of origin. Between 2002 and 2009, the number of immigrants from Peru has more than tripled, from 38 000 to 131 000. They now account for 37% of the migrant population, followed by Argentines (17%), Bolivians (6%), Ecuadorians (5%) and Colombians (4%).
