Sažetak
Our presentation has two goals. The first goal is to demonstrate a possibility for clustering of data suitable for presentation in the form of a histogram, i.e. to find units (or in our case populations) that are similar by structure to each other. Similarity or distance of the items has to be defined by a distance measure. There are wide range of measures that can be used. Among others, we will use the Euclidean distance. The second goal is to demonstrate a possibility for graphical visualization of the population pyramids and the geo-spatial presentation of the clustered data using R programming language. As an example, we use census data from the Croatian Bureau of Statistics for 20 Croatian counties and the City of Zagreb for the years 2001 and 2011. Visualization and clustering of counties directs attention on change in populations’ age structure and indicates that pattern of population aging is different among counties in Croatia.
