The PAM and CLARA algorithms were applied to the analysis of population's ageing of society in the EU and EFTA countries. In the calculations, statistics data of population by age at NUTS-2 level for the EU and EFTA countries were applied. Obtained results were compared with results of clustering based on the k-means algorithm (Hartigan-Wong).
