Prison conditions in Chile are generally poor. Prisons often are overcrowded and antiquated, with substandard sanitary conditions. In November 2006 there were approximately 43,500 prisoners in prisons designed to hold 28,700 inmates. Prisons in the Santiago Metropolitan Region were at nearly double capacity. The 2006 Diego Portales University School of Law study on prison conditions reiterated that prison services such as health care remained substandard. Prison food meets minimal nutritional needs, and prisoners can supplement their diets by buying food. Those with sufficient funds often can "rent" space in a better wing of the prison.
