The research into social stratification in Serbia, the results of which form the foundation of papers presented in this book, is continuation of a long-term scientific project of research on the transformation of class structure in the country. The project was launched in 1989, while a series of surveys since conducted created a time-series study of systemic changes of social structure, covering three points in the emerging and consolidation of capitalist social relations in Serbia: relations prevailing just before the breakdown of the socialist system, relations existent during the ten years of the blocked post-socialist transformation, and relations formed during the accelerated consolidation of capitalism in the first twenty years of the this century. Surveys made on nationally representative samples of adult population took place in 1989, 1993, 1997, 2003/2004, 2012 and 2018. The papers published in this book cover the following topics: vertical class mobility, systemic changes of relations in the sphere of economy and politics, value changes and some methodological aspects.
