A correlation of the measurement techniques and their outputs in the study of the subnational level of politics

At the beginning of the third decade of the 21^st century, the role and value of subnational research in comparative political science are further strengthened, given that the political life of society is moving in two interdependent directions: localisation and internationalisation. Instead, the specifics of the subnational topic contribute to changes and innovations in the implementation of various methodological techniques in the study of subnational units and their structural elements. However, the question of correlating outputs of techniques – objective and subjective – still remains unresolved, and therefore actualises the following formulation: how they appear equivalent in the practical plane, as their theoretical context is illustrated balanced within equivalence in spatial research politics on a subnational scale. In other words, whether the results of each technique are approximate or distinctive from each other from the point of view of the final situation. In the article, a variable degree of correlation has been demonstrated between both techniques and also a hypothesis has been presented about the nature and type of such interactions on the example of three cases (Transcarpathian, Lviv and Chernivtsi regions) in Ukraine in the period 2010–2015.
