A lengthily prepared secessionist attempt culminated, in Catalonia, on Autumn of 2017. A Declaration of Independence was approved by the Regional Parliament, the 27 th October, and followed by a suspension of the Autonomy Rule, dictated by Central Government, after due permission by Spanish Senate in accordance with the Constitution. This resulted in the destitution of the Regional Government and the dissolution of the Autonomous Parliament. The secessionist movement had demonstrated great force not only by mobilizing huge amounts of followers repeatedly but on elections and challenges perceived as victories against the State. A rise of influence, however, showed by unionist forces both at street demonstrations and on the last Regional election (21 th. Dec. 2017), has created a situation that appears as an entrenched draw, within a deeply divided society. I discuss here social and economic profiles that distinguish two big segments of Catalan citizenry, in relation to their options in favor of or against secession. Those profiles that can be traced to a recognizable ethno-cultural frontier based on family origins and habitual language may also contribute to enhance current tensions.
