摘要：Clustering method is a widely used technique for discovering the structure of a statistical population.
Classical clustering techniques have as result a partitioning of the elements of a considered set so that
any element of the initial set belongs only to one cluster. The fuzzification of these techniques is their
natural extension reflecting to a greater extent the reality that an element can belong to multiple clusters
at the same time. This paper shows a classification of Romania’s counties depending on their
demographic structure determined by age groups, by using fuzzy clustering techniques.
