Abstract

Particularly since the early 2000s, the European Union (EU) has undergone significant expansion through the accession of numerous countries, and it presently comprises 27 member states. There exists a multifaceted demographic change occurring within the member states. The primary factors influencing this demographic change include the ageing of the population, intra-member state population mobility, and immigration from countries outside the Union. These components exert varying effects on each member state, and the 27 member states exhibit significantly diverse demographic structures in relation to one another. This study aims to visually illustrate the similarities and differences in the populations of EU countries by age groups. To that end, four age groups (0-14, 15-24, 25-64, and 65+) were determined in the study. The populations of the EU countries by age groups as of January 1, 2023, were sourced from EUROSTAT. The populations were subsequently analysed, followed by the establishment of the appropriate number of dimensions and the visualisation of the populations of the EU member states categorised by age groups using correspondence analysis, a dimensionality reduction technique that allows researchers to visualise the results graphically without losing significant information. The study’s findings indicate that the demographic structures of the EU member states differ from one another, revealing various groupings among them. The study thus assists decision makers in comprehending the demographic composition of member states and developing a strategic roadmap, as well as in taking various measures or steps if required.
