Query: What percentage of voters rejected the separation of church and state in 1980?
Context: The Swiss Constitution of 1848, under the recent impression of the clashes of Catholic vs. Protestant cantons that culminated in the Sonderbundskrieg, consciously defines a consociational state, allowing the peaceful co-existence of Catholics and Protestants. A 1980 initiative calling for the complete separation of church and state was rejected by 78.9% of the voters. Some traditionally Protestant cantons and cities nowadays have a slight Catholic majority, not because they were growing in members, quite the contrary, but only because since about 1970 a steadily growing minority became not affiliated with any church or other religious body (21.4% in Switzerland, 2012) especially in traditionally Protestant regions, such as Basel-City (42%), canton of Neuchâtel (38%), canton of Geneva (35%), canton of Vaud (26%), or Zürich city (city: >25%; canton: 23%).
