Theoretical and methodological bases of influence of social and economic factors on ethnopolitical processes in segmented societies are generalized and analyzed. The general regularities and possible consequences of the direction of their development for the general political situation in the country are revealed. Most attention is paid to conflict theories, functional approach, theories of modernization and culturological aspects of socio-economic inequality. Their critical analysis is carried out. The significant heuristic potential of existing theories and the need for their practical use are emphasized. It is noted that in most theoretical approaches, ethnicity is seen as a symbolic and social capital that can be used by political actors to achieve their political and economic goals both within the country and abroad. In this regard, it is pointed out the need to take into account the socioeconomic characteristics of ethno-national groups in the system of statistical data processing by the State Statistics Committee of Ukraine. This will make it possible to monitor the processes of ethnic social stratification in dynamics and provide research with appropriate information support. It is noted that taking into account the achievements of scientific knowledge and in order to increase the effectiveness of state ethnic policy, the application of the approach(conditionally it can be called "status quo"), which involves the transition from the paradigm "we – they" to the paradigm "I and we". The main task of this approach is to ensure that every citizen can freely and fully participate in the socio-political life of the nation, have opportunities for social mobility, while maintaining their own regional, local, national-cultural, spiritual, religious and personal identity
