The purposes of this study are to estimate the age and sex of the human skeletal remains from the Ikenohata-shichikencho site; to reconstruct the demographic features of the Edo people; and to discuss whether the materials represent the demographic structure of the Edo people. This study analyzes the right pelvic bones of 394 individuals from the Ikenohata-shichikencho site, which are adult individuals of 15 years of age or above. The sex of 391 adult individuals was determined, resulting in 235 men and 156 women. In the age-at-death distribution of 371 individuals there is a peak around the age groups of under 30 and of 30-39, and there are few individuals above the age of 60. The sexual difference in the finding that females have a significantly younger death distribution than males could reflect the general living population of the Edo people. However, death tends to be concentrated in young individuals and thus the proportion of elderly individuals is very low. The reconstructed age-at-death distribution may include the methodological fault that leads to the systematic underestimation of age in elderly adults. If so, this denies the possibility that the age-at-death distribution of the Ikenohata-shichikencho sample represents the reality of the living population.
