Factor analysis by principal components with the Warimax rotation has been conducted on 26 anthropometric traits of 2200 children aged 6.75 to 17.25. Mean values of traits have been calculated at half-year intervals within each sex. Two orthogonal components accounting 96.5% of the total variation have been chosen. Individual factor values have been analysed to determine their relationship with age. The classification of objects is constructed by the cluster analysis in the space of factors. Four different morphological types within each sex have been found. The age limits between the revealed clusters differ for both sexes.
