 From the end of World War II until 1953, according to various data, between 250,000 and 350,000 people emigrated from these regions.Since the Italian population before World War II numbered 225,000 (150,000 in Istria and the rest in Fiume/Rijeka and Dalmatia), the remainder must have been Slovenes and Croats, if the total was 350,000.According to Matjaž Klemenčič, one-third were Slovenes and Croats who opposed the Communist government in Yugoslavia, but this is disputed.
