Results: The mean sacral index of sacrum in males is (99.68± 7.15) and in females (109.86±8.72). Calculated range for males is (78.23-121.13)and Demarking point is <83.70. Calculated range for females is (83.70-136.02) and Demarking point is >121.13. ‘P’- Value is 0.000 which isconsidered to be statistically highly significant. Bone identified by DP is (27.77%) males and (33.92%) females.

Conclusion: Since sacrum is a component of pelvic girdle with Anatomical difference between the two sexes, it itself becomes important for identification of sex in human skeleton system.
