In short
Church attendance in Switzerland is now the exception rather than the rule. Only 9.4% of Swiss Catholics attend Sunday Mass, though 16.6% attend about once a month (2023). At the same time the two main churches are shrinking fast: over a decade Roman Catholics fell from 38% to 30% of the population and Reformed Protestants from 26% to 19%, while the non-affiliated rose to 36.8% in 2024, up from 23% in 2014. Evangelicals stand apart, with 30.3% attending a service at least weekly.

Switzerland was long a country split between Catholic and Reformed Protestant regions, but regular church attendance has become the exception. Only 9.4% of Swiss Catholics attend Sunday Mass, and a further 16.6% attend about once a month, according to the Swiss Federal Statistical Office. Behind that lies a deeper shift: over the past decade the two main churches have shrunk sharply while the share of people with no religion has climbed to 36.8% of the population in 2024, up from 23% in 2014. Evangelicals are the clear outlier, with 30.3% attending a service at least weekly. The figures below all draw on the Swiss Federal Statistical Office, the most authoritative source on religion and church attendance in Switzerland.

How often the Swiss attend
Formal membership in a church tells you little about lived practice in Switzerland. Among Catholics, weekly Mass attendance has become a minority habit, and even monthly attendance covers only a modest share of members. The Swiss Federal Statistical Office measures these shares through its survey on language, religion, and culture.
Only 9.4% of Swiss Catholics attend Sunday Mass, according to the Swiss Federal Statistical Office.

The decline of the main churches
The bigger story behind falling attendance is falling membership. Over the past decade both of the historic churches, the Roman Catholic Church and the Reformed Protestant (Evangelical Reformed) Church, have lost a large share of the population, driven by exits and by generational change.
Roman Catholics fell from 38% to 30% of the population over a decade, according to the Swiss Federal Statistical Office.
Reformed Protestants fell from 26% to 19% of the population over a decade, according to the Swiss Federal Statistical Office.

Who still attends: evangelicals and the rise of the nones
As the main churches shrink, two groups stand out. The non-affiliated, often called the nones, have grown into the fastest-rising group in Switzerland. At the other end, evangelical free churches keep a level of weekly attendance that the historic churches no longer approach.
People with no religion rose to 36.8% of the population in 2024, up from 23% in 2014, according to the Swiss Federal Statistical Office.
30.3% of Swiss Evangelicals attend a service at least weekly, far more than other groups, according to the Swiss Federal Statistical Office.

How we compiled these statistics
Every number on this page comes from the Swiss Federal Statistical Office and is dated to the year the data were collected. Religious affiliation shares, such as the Roman Catholic, Reformed Protestant, and non-affiliated figures, come from the structural survey of the population. Attendance shares, such as the Catholic Sunday Mass rate and the evangelical weekly rate, come from the survey on language, religion, and culture and are self-declared estimates. Where data years differ, we use the most recent published year and label it.
