Differences in Life Expectancy at the Level of EGTC TRITIA Regions

The main goal of the paper will be to compare the differences in life expectancy at birth of the four European regions that launched territorial cooperation in 2013 within the European Grouping of Territorial Cooperation TRITIA. The main actors in this effort to expand cooperation were the Moravian-Silesian Region, the Opole Voivodeship, the Silesian Voivodeship and the Zilina Self-governing Region. The four border regions at the common borders of the Czechia, Poland and Slovakia are an area where many economic and social decisions took place in a very similar way. Nevertheless, the border barrier has often acted as a major obstacle to long-term co-development. By analysing life expectancy at birth for the last twenty years since 2001, we will try to show the differences in this very important indicator of sustainable development at the level of the four monitored regions. Subsequently, we will try to justify the differences and find the causes of the differences, especially the social pillar of sustainable development. The analysis of the life expectancy at birth of these four regions will be supplemented by an assessment of its achieved level in comparison with other regions of the Czechia, Poland and Slovakia. In the case of the Czechia and Slovakia, it will be at the level of their regions (NUTS 3), in the case of Poland at the level of its voivodships (NUTS 2).
