Electorate
All citizens of Chile as well as foreigners residing legally in Chile for at least five years, who are 18 years of age or older on the day of the election, are eligible to vote. Enrollment in Chile is automatic for those aged 17 and older and voting is voluntary. Chileans are not allowed to vote overseas. Before 2012 voting was compulsory for life for Chilean citizens who wished to enroll.
Women's suffrage was achieved in 1934 for local elections. In 1949 voting was extended to literate women over 21. Full universal suffrage was achieved in 1970, with men and women over 18 eligible to vote, regardless of their ability to read and write.
