In Croatia, Scala families are predominantly Italians (from Rijeka ), rarely Croats (from Karlovac ). In the past century, relatively most of Croatian residents bearing this family name were born in Rijeka and Buzet.
Prevalence
Only a few people with faimily name Scala live in Croatia today, in three households only. There were 20 of them in the middle of the past century, and their number halved. They are located in three Croatian cities only: in Rijeka (<5), Karlovac (<5), and in Novigrad (<5).
In the sources analysed in the project Acta Croatica so far, the name is mentioned over ten times, the first time 1902 in source Hartmann's General List of Apartments in Zagreb.
