Even before the city was formally annexed by Italy, the Croatian population started to leave the city or was forced out by the authorities and Italian nationalist activists. Some 1500 government workers of Croatian nationality lost their jobs, Croatian schools and newspapers were closed, even church services in Croatian were banned. As a result, the Croatian population decreased from 15.731 in 1910 (31.71%) to only 4.970 in 1925 (10.8%). Most Croatians moved across the Rječina river to Sušak (the Rječina river would become the new border between Italy and Yugoslavia). The Italian population increased from 23.283 in 1910 (46.94%) to 36.251 in 1925 (79.1%) in large part by immigration from Italy. Most of the German and Hungarian population also left the city.
