| Outline of Final Research Achievements |
In order to clarify the population dynamics of Jomon Period in western Japan, this study examined the creation of a spatial database of archaeological sites, estimates of settlement system and the size of residential groups, and a model for predicting the presence of Jomon-period sites. To examine the true change of archaeological materials, 14C dating data were examined. In order to examine the spatial bias, a prediction model of Archaeological sites was created and examined. Then, changes in society and settlement system and their factors were examined using agent-based simulations. As a result, various issues for examining population dynamics were clarified, and a perspective on methodology was obtained.

| Academic Significance and Societal Importance of the Research Achievements |
人口動態を研究するためには、様々なバイアスが存在することがこれまで指摘されてきた。本研究では、西日本における縄文時代の人口動態の評価について、従来用いられてきた遺跡数や住居址数だけではなく、年代測定、居住集団の規模、居住形態、遺跡存在予測モデルといった側面を考慮して検討を行った。統計的分析またはシミュレーションを用いることで、様々なバイアスを軽減する方法を模索し、これまでよりも精度の高い人口動態の推定ができるようになる。そして当該地域における文化・社会変化との関連を詳細に論じることが可能となる。
