There are 618 citizens of the state, and is composed of clergymen and lay people who, with exceptions, retain Vatican citizenship only as long as they reside and exercise an office within the territory of the state.
Only 246 people (including 104 members of the Swiss Guards) live within the walls.
About half of the citizens therefore do not reside in the Vatican State, but in other countries, above all for service reasons (in particular diplomatic staff).
The conferment and loss of citizenship, authorizations to reside in the territory of the State, and the formalities for access are governed by specific provisions, issued in line with the Lateran Treaty.
Citizenship is not acquired either because you are the son of Vatican citizens, or because you are born inside the walls, but by concession of the Pope, who therefore can revoke it.
Inside the Vatican City, in the shadow of the dome of St. Peter’s Basilica, there are ordinary everyday scenes. Of course, the families of the Swiss guards in particular animate the life of the Vatican courtyards.
In the courtyard of Apostolic Almsgiving, for example, it is easy to find “parked” the bicycles that children use especially in the afternoon, after school and after the closure of the Vatican pharmacy, or Annona, when the streets of Vatican City have less car traffic.
