Abstract
This article reveals the socio-economic factors of centrifugal tendencies in the modern Spain (the Basque Country case) from 2009 to 2020. A correlation is revealed between the preferences of Basques regarding the territorial and political structure of Spain and a number of socio-economic factors such as GDP per capita, the unemployment rate, the level of average wages and the Consumer Price Index. The article also acquaints readers with the attitude of the Basques towards the regional government and their assessment of the economic situation in the region. The author concludes that one of the key factors is the Consumer Price Index, since as the price level rises, separatist sentiments also grow. Another important factor is the attitude of citizens towards the regional government: despite the assessment of the economic situation (bad or good), if the attitude towards the regional government is positive, centrifugal tendencies become more intense.
