Background: Stature is considered to be one of the “big fours” in forensic anthropology. Though Carrea's Index was published as early as 1920 it has not been validated in any other population apart from the Brazilians.Aim: The present study was conducted to validate Carrea's index in stature estimation in two different racial populations in India.Materials and Methods: The study was carried out in a sample of 100 persons comprising of 25 Aryan males, 25 Aryan females, 25 Dravidian males, and 25 Dravidian females in the age group of 18–30 years. The maximum and minimum stature of all individuals was estimated by Carrea's Index. The actual stature was measured by an anthropometer. The estimated stature was compared with the actual stature and percentage of success was calculated.Results: The Carrea's Index was found to be valid in predicting the stature of 80% Dravidian and 84% Aryan males, the difference being statistically insignificant (Fisher Exact test–0.16; P = 0.99). The stature of 76% of females in both Aryan and Dravidian races was successfully predicted by Carrea's index. Regression analysis showed that the minimum estimated height was more valid in estimating the stature of Aryan and Dravidian population.Conclusion: The validity to use Carrea's index in Aryan and Dravidian population was evaluated and found to be valid.
