Vatican City - Religion
07/09/2019
Almost all of Vatican City's little more than 800 citizens either live inside the Vatican's walls or serve in the Holy See's diplomatic corps in embassies (called "nunciatures"; a papal ambassador is a "nuncio") around the world.
The Vatican citizenry consists almost entirely of two groups: clergy working as officials of the Vatican as a state or of the Catholic Church; and the Swiss Guard.
Most of the 3,000 lay workers who comprise the majority of the Vatican work force reside outside the Vatican and are citizens of Italy, while a few are citizens of other nations.
As a result, all of the City's actual citizens are Catholic.
Catholicism is the state religion and all the places of worship inside Vatican City are Catholic.
