This paper is an attempt to present changes of living standards, as an element of
sustainable development. In the article, the authors present a literature review concerning
the sustainable development concept and its dimensions, as well as, its linkage with the
living standard concept (and broadly – with the quality of life category). The main goal is a
statistical analysis of the living standards of the inhabitants of the Carpathian Euroregion,
which was conducted using the data from the years 2008-2016. Within the analysis, the
authors presented three groups (clusters) of regions belonging to Euroregion and analyzed
the differences between them, as well as, the main factors responsible for belonging to the
applicable group. In the article, three hypothesis were examined. Only two of them were
confirmed (one in limited scope)
