 The percentage of Chileans with household incomes below the poverty line – defined as twice the cost of satisfying a person's minimal nutritional needs – fell from 45.1% in 1987 to 11.7% in 2015, according to government polls.Critics in Chile, however, argue that poverty figures are considerably higher than those officially published; until 2016, the government defined the poverty line based on an outdated 1987 household consumption poll, instead of more recent polls from 1997 or 2007.According to critics who use data from the 1997 poll, the poverty rate goes up to 29%; a study published in 2017 claims that it reaches 26%.
