Comparison of Cranial Capacity of the Non-Tribal with Keer Tribal Population of Madhya Pradesh

Cranial capacity is one of the most important components of the physical anthropometry, which is useful in differentiation of racial and sexual differences and indirectly reflects the brain volume in different populations. This study was carried out by using linear dimensions of head (Lee Pearson's formula) on 800 healthy 20 - 25 years old subjects (of which were 400 males and 400 females) from Keer tribe and Non-tribal population of Madhya Pradesh. The mean cranial capacity and SD in Non-tribal males and Non-tribal females were 1380.524 ± 94.633 cc and 1188.758 ± 91.164 cc respectively. The mean cranial capacity and SD in Keer males and Keer females were 1252.857 ± 70.989 cc and 1094.441 ± 81.289 cc respectively. This study has shown a significant (p<0.05) difference between the same gender populations of Keer tribe and Non-tribal population, with the absolute values being higher in Non-tribal group than in Keer tribe group.
