The contribution presents findings from the research on a constitution of new ethnic identities in Alps-Adriatic region. The key question dealt here with was to which extent the recent demographical processes impact the peripheral, mountainous, and ethnically specific cross-border region between Slovenia and Italy. In lay and professional discourse there is still omnipresent mentality of extinguishing Slovene minority in Italy. Applying various demographical methods the article resolves the demographical processes and quantifies the extent of the local Slovene speakers. The author argues that the recent demographical processes of heavy depopulation tend to stabilize towards stagnation. Depopulation is stronger in the Slovenian part of the region, though the traditional Slovene-speaking areas in Italy aren’t as threatened as the adjacent Friulian areas. New migration trends along with the generally low fertility contribute to changes in traditional dualistic structure and bring refreshment to remote parts of the border region as well.
