What are the burning issues in Swiss votes?

Since 1848, the Swiss have had their say on over 600 nationwide ballots. Which have been the most popular issues in recent times?

The Swiss go to polls about four times a year in nationwide votes. Using data compiled by the Centre for Research on Direct Democracyexternal link, which tagged all national votes with keywords, swissinfo.ch has analysed the most popular voting themes since Switzerland's first constitution in 1848. Each ballot was assigned between one to three themes.

The graphic below offers a more complete picture of vote outcomes by topic over time.

It shows three types of votes, all of which are part of Swiss-style direct democracy: mandatory referendums, optional referendums and people's initiatives. These different types of votes are explained at the end of this article.

In general, people's initiatives are rejected more often than referendums. Swiss citizens turn down about 90% of all people's initiatives, while they accept over 70% of mandatory referendums.

Although defining the main topic of a ballot can be viewed as slightly subjective, the data shows that there has been recent rise in people's initiatives on the environment, immigration and the status of women. We also know that since the 1970s, the number of national people's initiatives put to vote has increased.
