On August 24, at the University of Concepción School of Law, the book “Desiguales. Orígenes, cambios y desafíos de la brecha social en Chile” of the United Nations Development Programme (UNDP) was presented. As stated in the project’s website, one of its products is this book, which “contains data that quantify socio-economic inequality, a historical review from the times of the Conquest and a panorama of how we live inequality in the present. It also provides an analysis of the mechanisms that reproduce it and of the transformations that these mechanisms have experienced in the last decades” (Available at www.desiguales.org).
