The aim of the study is to analyse the changes in the socio-economic performance of Hungarian regions in the previous decade. The first part of the paper deals with the epistemological and methodological questions of the analysis of temporal change of spatial differences of various individual and composite socio-economic indicators. In the second part the empirical analysis will be conducted at the county level (NUTS 3 level, 20 spatial units), including a wide range of economic, social and demographic variables. The analysis is concerned with processes over an eleven-year period, 2010-2020. Our methodology combines the analysis of individual indicators with the use of complex aggregated indicators composed of several indicators. Some of the counties show higher level of socio-economic performance with more developed infrastructure, higher quality of education and stronger economic base. However, the picture is not entirely uniform, there are small, moderately positive and negative movements compared to the national average.
