Hdi index dimensions in the context of hybrid threats

The Human Development Index (HDI index) is considered a summary index of the perception of human well-being in a selected economy. It consists of 3 sub-dimensions: the population's education, health and income. It is considered a vital indicator of the perception of the state of human development, and based on it, countries are compared in the mentioned areas. Our contribution aims to analyze the position of European countries in the context of the HDI index and, at the same time, to apply expanded indicators of education and health. Subsequently, we apply these new, supplemented dimensions in comparing the selected countries and in the context of hybrid h. Within the methodology, we use the methods of agglomerative cluster analysis and paired T-test.
