Abstract: Somatotype of Han urban and rural students aged 7 to 18 was analysed in a group of 3088 individuals (1489 boys and 1599 girls) in Inner Mongolia with the Heath-Carer anthropometric me- thod. The results showed that major somatotype of urban and rural boys was mesomorphic ectomorphy, then were mesomorph-ectomorph and ectomorphic mesomorphy. In urban and rural girls, major somato- type was mesonorphic endomorphy, then were central and endomorphic ectomorphy. In the period from age 8 to 13, the somatotype of boys or girls has a significant difference between urban and rural students in a same age and same sex group. After 13 year, the somatotype between them is similar.There was a significant difference in somatotype between males and females of urban and rural students.
