Abstract: In 1995, a total of 1564 Mongolian students ( 723 boys and 841 girls) aged 7 to 19 years were somatotyped according to the Heath-Carter somatotyping method. Findings indicated that male mean somatotypes changed slightly with growth. Most of individual somatoplots distributed in mesomorphic and mesoectomorphic zone on the somatochart. For female, mean soma to types varied greatly , shifting from central to mesaendomorph. Comparisons of male and female somato type means showed significant dimorphism in 11— 19 years groups. From comparing Mongolian student 's somatotype means with those o f Han and other foreign groups ( especially for male) , it is concluded that there are differences among different ethnic groups.
