Outline of Final Research Achievements	In this study, we analyzed the phenomenon of double aging for housing and residents, which is expected to generate a reserve army of vacant houses. The geographical factors behind the occurrence of vacant houses and the measures to prevent their occurrence were examined. A survey of suburban housing complexes in metropolitan areas where rapid aging is predicted was also conducted to identify the different causal factors for vacant houses depending on regional characteristics, such as household composition and living environment, as well as the maintenance and community conditions for aged houses. The study also identified areas where measures should be proposed to stimulate demand for resettlement using GIS to capture regional differences in the current distribution of vacant houses and differences in the occurrence of vacant houses in the future.

Academic Significance and Societal Importance of the Research Achievements	行政による現状の空き家政策は管理不全に陥った放置空き家等に重点が置かれ、今後の空き家の増加が懸念される大都市地域では、その発生を未然に防ぐ対策が喫緊の課題となる。本研究では地理学の視点から、特に高齢化が目立つ近郊住宅団地内の地区レベルでも空き家の発生要因に差があることを把握し、予防対策を優先すべき地区選定の必要性を指摘した。また、予算や人的資源に制約のある自治体の空き家予防対策を補完する手段として、予備軍となる高齢単身・夫婦世帯を優先対象とし、自治会やNPO、民間事業者等と連携した円滑な相続や住宅流通等に関する相談・支援体制の強化の重要性を提起した。
