Three referendums were held in Switzerland during 1925.^[1] The first was held on 24 May on a popular initiative calling for insurance for invalidity, old age and bereavement, and was rejected by voters.^[1] The second was held on 25 October on a federal resolution on the settlement and residence of foreigners, and was approved by a majority of voters and cantons.^[1] The third was held on 6 December on a federal resolution on insurance for invalidity, old age and bereavement, and was also approved by a majority of voters and cantons.^[1]

The May referendum was a popular initiative,^[1] which required a double majority; a majority of the popular vote and majority of the cantons.^[2] The decision of each canton was based on the vote in that canton.^[2] Full cantons counted as one vote, whilst half cantons counted as half.^[2] The October and December referendums were both "obligatory" referendums, which also required a double majority.^[2]
