During the late 1940s and in the years following the division of the Territory, up to 40,000 people (mostly Italians) chose to leave the Yugoslav B zone and move to the A zone or Italy for various reasons: Some were intimidated into leaving, and some simply preferred not to live in Yugoslavia.
1940. aastate lõpus ja territooriumi poolitamisele järgnenud aastatel otsustasid kuni 40 000 inimest (peamiselt itaallased) erinevatel põhjustel lahkuda Jugoslaavia B-tsoonist ja asuda elama A-tsooni: neist mõnda ähvardati ja mõned lihtsalt eelistasid mitte elada Jugoslaavias.
