3 regions/countries of Europe in which Indo-European languages do NOT predominate are :
Uralic languages are spoken in:
Estonia: Estonian
Finland: Finnish and Swedish
Hungary: Hungarian
Explanation :
The Uralic or Uralian language family consists of 38 languages spoken by approximately 25 million people, predominantly in Northern Eurasia
Uralic is a large and diverse family of languages spoken in northern and eastern Europe and northwestern Siberia. Among the better-known Uralic languages are Finnish, Estonian, and Hungarian.
The most demographically important Uralic language is Hungarian, the official language of Hungary.
Two other Uralic languages, Estonian and Finnish are also spoken by millions.
Indo-European divided into different branches because of isolation of different speakers. Basque is the only non-Indo-European language currently spoken in Europe.
Finnish, Hungarian and Estonian belong to the Uralicfamily, and Basque has no genetic relation to any other language.
A core-periphery relationship is is defined by the exploitation of the periphery countries by the core countries. The last one is the only one that shows some type of exploitation. I hope this helps.
