According to the studies by J. Cvijić, almost 90% of the families of Šumadija descended from settler families of various Serb ethnographic groups. The Dinaric group was predominant, while other South Slavic regions are included in lesser percentages. This diverse population blended, mutually permeated and leveled, thus creating an ethnographic group (the Šumadinci), with characteristical psychical traits.
