Istria is the biggest peninsula in the Adriatic Sea and a multiethnic region divided between Croatia, Italy and Slovenia.
People also declared an Istrian identity in the Primorje-Gorski Kotar County, the county where the rest of Croatian Istria is located,[3] therefore making the number of people declaring an Istrian identity in Croatia a total of 25,409.
[4] Most of these people in these counties were ethnic Croats, but there were also Istro-Romanians declaring themselves as Istrian.
[3] Later, the 2021 Croatian census saw a decrease on Istrian self-designation, as 10,025 inhabitants of the Istria County used it.
[5] It has been proposed that Istria gain greater autonomy within a more decentralized Croatia.
