The Use of Cluster Analysis to Assess the Threats of Poverty or Social Exclusion in EU Countries: The Case of People with Disabilities Compared to People without Disabilities

Abstract

The main research objective was to assess the range of threats related to poverty or social exclusion in EU countries among people with disabilities as compared to people without disabilities. The research used the available poverty determinants, including the percentage of low work intensity, the percentage of low income, the percentage of material deprivation, the poverty risk rate, the percentage of severe disability, living conditions and population income, and the overall risk of household poverty or exclusion, which are available in Eurostat databases. The data used in the research relates to 2018 and was published in 2021. The research used cluster analysis, more specifically one of the agglomeration clustering methods, i.e., Ward’s method. Separate cluster analysis using Ward’s method was carried out for people with disabilities and for people without disabilities. The analysis identifies two clusters among people with disabilities and two clusters among people without disabilities. In the group of people with disabilities, cluster 2 includes 19 countries with a higher risk of poverty or social exclusion, while cluster 1 includes eight countries with a lower risk of poverty or social exclusion. In turn, in the group of people without disabilities, cluster 2 includes nine countries with a higher risk of poverty or social exclusion, while cluster 1 includes 18 countries with a lower risk of poverty or social exclusion.
