     View Summary

    本研究では、地方圏を対象として、近年の人口分布がどのように変化し、現在どのような特徴を持つのかを明らかにするために、1990年代以降の市町村および市町村よりもミクロな地域を単位とする地方圏全体の人口分布を、人口学的なメカニズムを踏まえて検討するものである。そのために、都道府県別や市区町村別単位の分析、市区町村よりもミクロな地域単位で農村及び都市の内部の人口分布変化を分析することが本研究の具体的な課題となる。
    2021年度については、2022年度以降に分析を本格化させるために必要になるデータ整備を進めるとともに、既存研究の整理や基礎的な分析を実施した。このうち、データ整備に関しては主に2点を実施した。1点目は、東京大学空間情報科学研究センターとの共同研究を申請することで1995年から2015年までの国勢調査の地域メッシュデータ利用の認可を受けて、GIS上での分析が可能な形へのデータ整備を行った。2点目は、2020年国勢調査のデータが昨年度に公表されたことを受けて、都道府県別および市区町村別に時系列で分析可能な形でのデータ整備を進めた。
    既存研究の整理や基礎的な分析のうち、前者については英文で公表された人口地理学の重要文献を収集し、知見を整理した。後者の基礎的な分析については、都道府県や市区町村を単位として、これまでの自然別社会別人口変化や今後の人口見通しへの影響について検討を進めた。また、地域人口の変化に影響を及ぼす近年の人口移動の趨勢についての検討も実施した。

    People's attitudes and behaviors are shaped by the region in which they live. In order to quantitatively understand the relationship between individuals and regions, this study constructed a multilevel geographical data that combines both types of information, conducted statistical analysis, and made the data publicly available. The study collected data on 30,000 residents of major cities in Japan, and based on detailed address information, clarified various regional differences in people's attitudes and behaviors, as well as the factors that have contributed to such regional differences. In addition, as related basic research, the impact of declining response rates in social surveys on regional analysis and the usefulness of new survey methods using the Internet environment were clarified.

     View Summary

    This research attempts to examine Japanese partnership, marriage, fertility, and inter-generational relations from an international comparative perspective. More specifically, we firstly conducted the Japanese Generations and Gender Panel Survey (GGS) and collected micro-data concerning Japanese family relations and formation. In the second place, we collected macro-data on labour policy, welfare policy, family policy, wages, education, and employment in Japan. We analyzed partnership formation, childbearing, child-rearing and inter-generational support in Japan by combining the micro-and macro-data we collected. Furthermore, thanks to a comparative analysis between Japan and other developed countries, we draw policy implications for the sustainable development of Japanese society undergoing lowest-low fertility with an ageing and shrinking population.

     View Summary

    Despite the need for reliable information on sexual orientation and gender identity, there is a lack of knowledge based on quantitative data in Japan. This research developed questions to capture sexual orientation and gender identity (cisgender or transgender) through focus groups and other methods. Using a questionnaire that includes SOGI questions and questions on employment status, economic status, mental and physical health, suicidal ideation, attitudes toward gender, family, and SOGI-related policies, and experience of being bullied, a mail survey was administered to 15,000 randomly selected residents of Osaka City in 2019. 4,285 responses were collected, and results of analysis by SOGI comparison of educational attainment, income, and physical and mental health were presented in academic conferences and papers. The research indicated the significance of including SOGI in random sampling surveys.

     View Summary

    With many of subnational areas undergoing accelerated depopulation and population aging, there have been growing concerns about the future sustainability of population reproduction at the regional level in Japan. This study investigated the spatial aspects of low fertility rates in Japan. The main results are summarized as follows:(1) we confirm that the fertility rate of foreigners has suppressed the TFR in most prefectures despite the recent growth in the foreign population; (2) we suggest that the lower fertility rate of the Tokyo Metropolitan Areas cannot be largely attributed to in-migrants from other part areas of the country; (3)we found that Okinawa Prefecture’s experience with regard to fertility does not offer an appropriate pro-fertility policy model for the mainland Japan.
    In order to facilitate solid understanding of these issues in an era of low fertility, we have published a book on the methodology of subnational population projections for practitioners and researchers.

     View Summary

    In this study, to establish geographical studies of social security, Japanese geographers who typically work individually cooperated to conduct an empirical study on the construction of community-based care systems, which is a major focus of social security policy in Japan. First, using techniques of geo-visualization in GIS, we systematically elucidated the large regional disparities in welfare, medical services, and social resources in Japan. Second, we clarified the characteristics, construction processes and problems of community-based care systems of various municipalities with different regional characteristics as well as care targets from the viewpoint of local governance. The results yielded by this collaborative approach exceed in scope and complexity those that can be achieved by conventional research by individuals working on their own.

     View Summary

    We compiled a database of survey questions used in quantitative family research in Japan. The database is organized by topics and includes a list of questions and response categories and details of the data collection method. From the database, we identified themes that can be analyzed using “integrative data analysis.” Such themes include the division of and time spent on housework and childcare; communication, companionship and decision-making between partners; relationship satisfaction; and ideas regarding families. In addition, we undertook an Internet survey (n=1271) in order to compare the response patterns when different response categories are used on the same question and when different questions are asked on the same phenomenon. We also conducted face-to-face interviews with 6 married couples on the survey questions in order to understand these response patterns.

     View Summary

    This study focuses on the methodology of local population projections. The main results are as follows. (1) The cohort component method was widely used for local population projections in national and international governments. (2) The cohort component method was applied to provide more accurate forecast than net migration models. (3) The questionnaire survey was conducted to obtain assumptions that fertility rates will change. (4) The fertility and mortality of foreign people had little influence on local population projections in Japan. (5) The household projections by municipality were examined and its practical problems were discussed.

  • 人口減少時代における持続的な地方の構築に関する人口地理学的研究

    2020  

     View Summary

    人口減少時代に入った日本では、人口の増減のあり方が地域によって多様であることから、人口分布にも変化が生じている。本研究では、1995〜2015年における地方に位置する複数の自治体を対象として、自治体内での人口分布の趨勢について整理することを試みた。対象とした自治体はいずれも島嶼部である北海道奥尻町、新潟県佐渡市、長崎県壱岐市、長崎県対馬市である。その結果、自治体内では地区によって人口変化にかなりばらつきがあること、人口維持ないし再生産されやすい地区が存在し、その様な地区が新たな地域の中心地となっている可能性があること、自治体内の人口分布は今後急速に変化する可能性があること、などが明らかになった。

  • 自然・社会増減別にみた人口変化要因の時空間パターンの変容に関する地理学的研究

    2017  

     View Summary

     本研究では、1968〜2015年における市区町村別の出生数、死亡数のデータを整理し、市区町村の人口変化に及ぼす人口の自然増減の影響について整理することを試みた。まず自然減少の市区町村について整理したところ、その数は増加傾向にあり、農山村地域のみならず県庁所在都市など人口規模の大きい都市地域でも近年は自然減少となっていた。続いて地域の人口増減と自然増減との関連を整理したところ、近年は多くの市区町村で自然減少が主たる要因となって人口が減少していた。さらに自然増減と人口構造との関連を整理したところ、人口の高齢化が進むと自然減少になる傾向がみられ、現状の出生率の水準では自然減少を避けることが当面は困難なことが明らかになった。
