The government started naming some of the dead on Tuesday. Nine had died in fires, one was electrocuted and five were shot, four of those by the security forces.
Eleven of the fatalities were in the Santiago region, while a Peruvian and an Ecuadorian were among the dead.
Chile’s human rights institute said more than 200 people had been taken to the hospital, almost half with gunshot wounds, while many others suffered eye injuries from pellets.
Since the unrest began, more than 2,600 people have been detained.
Tuesday saw almost none of the violence, looting or torching of public property and private businesses that marked the first few days of protest.
However, television images showed looters in one town smashing a bus into a department store before ransacking it.
In central Santiago, many shops and businesses that were closed on Monday reopened. Commuters and shoppers formed long lines at bus stops and supermarkets.
Only one of the Santiago metro’s seven lines – which normally carry three million people a day – was operational, although a fleet of 4,300 public buses took up much of the slack.
More than half of Santiago’s 136 metro stations suffered heavy damage during last week’s protests.
