Abstract: This paper studied the cephalic and facial types of Han nationality youths of 7-16 year' s old from Yulin district of Guangxi with the method of stratified random sampling. Nine items of cephalic and facial measurements of 1119 (634 males, 481 females) normal youths of Han nationality were investigated. The relationships between the youth' s cephalic and facial development and ages were compared and analyzed. Classifications are based on various cephalic and facial indices. The re- sults show that the nine cephalic and facial measurements grow with the increase of age besides the maximum head breadth, and significant difference between the males and females was found. The cephalic type of both sexes of Han nationality belongs to mesocephaly and brachycephaly according to the cephalic index; hypsicephalic type, to the length-height index of the head; acrocephalic type, to the breadth-heigth index of the head, euryprosopy and mesoprosopy, to the morphological facial index.
