Switzerland is a Christian country. Two-thirds of its population are either Catholic or Protestant (Reformed Evangelical). Freedom of religion in Switzerland also allows other religious communities to practice such faiths as Judaism, Islam and Buddhism.

Most people living in Switzerland are Christians. In addition to those who identify as Reformed Evangelical and Roman Catholic, there are followers of free churches and Orthodox Christianity. Switzerland is also home to other religious communities – Jewish, Buddhist, Muslim, Hindu, Sikh and more.

Switzerland's religious landscape has changed considerably in the last 40 years. While migration has resulted in religious pluralism, the number of people – particularly city dwellers – with no religious affiliation is growing.
