| Outline of Final Research Achievements |
The purposes of this study are to examine non-adult skeletons from the Sakai-kango-toshi 871 (SKT 871) site in Edo-period (AD 17-19th centuries) Japan, to estimate their age-at-death distribution, and to discuss whether paleodemographic estimates can yield appropriate mortality patterns of them. The use of the Bayesian method for fetal age estimation, assuming uniform priors, yielded a peak of deaths at 10 months of gestation. The age-at-death distribution obtained from the whole population further indicated the peak of deaths being at the fetal stage and the number of deaths decreasing with age. The concentration on full-term of gestation implied deaths related to birth, which is consistent with natural mortality. Another important finding of this study is that individuals aged less than 7 years accounted for about 98% of the deaths and there was no burial for adults.
