This development, which confirms the findings of Casparini and others (2011), took place in parallel with a sharp reduction in income inequality once the country had overcome the 2001-2002 crisis. Other cases in which school segregation has clearly increased are Colombia, Ecuador, Nicaragua, Peru and Uruguay. Between 1992 and 2011, the index of isolation rose from 0.274 to 0.391 in Argentina, from 0.217 to 0.318 in Colombia, from 0.244 to 0.301 in Ecuador, from 0.164 to 0.229 in Nicaragua, from 0.236 to 0.338 in Peru and from 0.332 to 0.382 in Uruguay.
