Through Voting, Democracy and World War II

History

In 1891, the South African Republic, commonly known as the Transvaal Republic, set a voting age of 18 years. The effort was, like later legislation expanding voting rights for women and impoverished whites, in part an attempt to skew the electorate further in favor of Afrikaner interests against uitlanders.

Prior to the Second World War of 1939–1945, the voting age in almost all countries was 21 years or higher. The U.S. state of Georgia lowered its age to 18 by referendum in 1943, for all elections including Congress and President, on the basis that many under 21 were at war; Kentucky followed suit in 1955. In 1946, Czechoslovakia became the first state to reduce the voting age nationally to 18 years, and by 1968 a total of 17 countries had lowered their voting age.

Australia, Japan, Sweden and Switzerland had lowered their voting age to 20 by the end of the 1960s.

Many major democratic countries, beginning in Western Europe and North America, reduced their voting ages to 18 years during the 1970s, starting with the United Kingdom (Representation of the People Act 1969), Canada, West Germany (1970), the United States (26th Amendment, 1971), Australia (1974), France (1974), Sweden (1975) and others. It was argued that if young men could be drafted to go to war at 18, they should be able to vote at the age of 18.

In the late 20th and early 21st centuries voting ages were lowered to 18 in Japan, India, Switzerland, Austria, the Maldives, and Morocco. By the end of the 20th century, 18 had become by far the most common voting age. However, a few countries maintain a voting age of 20 years or higher, and a few countries have a lower voting age of 16 or 17.

2020 to 2021

The vast majority of countries and territories have a minimum voting age of 18-years-old as of October 2020. According to data from the ACE Electoral Knowledge Network, 205 countries and territories have a minimum voting age of 18 for national elections out of 237 countries and territories the organization has data on as of October 2020. As of the aforementioned date, 12 countries or territories have a minimum voting age of less than 18, with 3 countries or territories at 17-years-old, and 9 countries or territories at 16-years-old. 16-years-old is the lowest minimum age globally for national elections, while the highest is 25-years-old which is only the case in the United Arab Emirates (UAE). This age of 25 was also the case in Italy for Senate (upper house) elections until it was lowered to 18 in 2021. Italy's lower house of Parliament, the Chamber of Deputies, has had a minimum voting age of 18 since 1975, when it was lowered from 21.
