Cluster analysis of countries with respect to fertility rate and other demographic factors

Summary/Abstract: The paper presents cluster analysis of 180 countries. In the first stage, countries were described by 11 demographic variables. Using all the variables led to a poor class structure, thus the procedure for variables selection was performed in the next stage. Only fertility rate, children mortality rate, population aged 5–20 (% of total) and population aged 60 and older (% of total) had a significant impact on the clustering quality. The best model was built using k–medoids. As a result the countries were grouped into three clusters.
