A study on an Indian population showed that both males (20/50) and females (28/50) had a hyperleptoprosopic face type according to the Martin and Saller face type classification (Mane et al.).
In the Garson classification of facial index there are five types: hypereuryprosopic ([less than or equal to]78.9), euryprosopic (79.0 to 83.9), mesoprosopic (84.0 to 87.9), leptoprosopic (88.0 to 92.9), and hyperleptoprosopic ([greater than or equal to]93.0) (Inaba et al.).
They observed face type as leptoprosopic (13.45 %) for females and hyperleptoprosopic (27.73 %) for males in a Brazilian population.
A study on a North-Eastern Nigerian population by Raji et al., showed that the hyperleptoprosopic face type was dominant in both sexes (70 % in males, 57.3 % in females).
The face is classified based on the FI or prosopic index as hypereuroprosopic or very short broad face (FI < 79.9), europrosopic or short broad face (FI of 80–84.9), mesoprosopic or medium round face (FI of 85–89.9), leptoprosopic or long narrow face (FI of 90–94.9), and hyperleptoprosopic
or very long narrow face (FI > 95).[sup], The facial indices in Yorubas (91.8 in males and 91.4 in females) [Table 2] examined in the present study implied that Yoruba males and females have the leptoprosopic face type.
The least common facial shape was hyperleptoprosopic (very long face) and it was 5% for both sexes.
(2013) had made a study in South Indian population and found that the dominant face type was hyperleptoprosopic, which was the least common type in Malays (5%) .
The second common type of face for males is leptoprosopic (20%) but for females it is europrosopic (24%) and the least common face type for Malays is hyperleptoprosopic (5%).

No hyperleptoprosopic female was found (Figure 2(a)).
However, though Evenks , Mongol , and Manchu  tribes belong to Mongoloid race, they show hyperleptoprosopic or very narrow face to leptoprosopic face.
