Danish constitutional and electoral age referendum, 1953

A constitutional and electoral age referendum as held in Denmark on 28 May 1953. Both proposals were approved by voters, leading to both a new constitution taking effect on 5 June, and the electoral age being lowered from 25 to 23 years, also starting on 5 June. Voter turnout was 59.1% for the constitution question and 57.1% for the voting age question.

According to the previous constitution of 1915, with changes from 1920, in order for a new constitution to pass, it must first be passed in one Rigsdag, which must then be disbanded, a new parliamentary election called, and the new parliament must then also pass the constitution, in unchanged form; and finally, a majority of voters in a referendum, with a requirement of at least 45% turnout, must also pass the proposed constitution. When the referendum took place on May 28, 1953, it concluded the last of these three steps, and the constitution could take effect on June 5.

The Ministry of Education of Denmark lists the changes from the previous constitution as follows:

One of the proposed changes in the new constitution was that the electoral age would now be decided by laws that required a binding referendum. Prior to the 1953 referendum, the electoral age was 25 years. The electoral age portion of the referendum asked whether the new electoral age should be 23 or 21 years, with 30.0% voting for 23 years and 25.0% for 21 years, thus passing the former of the two.
