長期避難所滞在と社会的脆弱性との関連

東日本大震災被災3県の社会調査データの分析から

抄録

This study aims to analyze the relationship between social vulnerability and long-term stay in shelters after the Great East Japan Earthquake disaster. We used data from a social survey conducted in 2016 targeting disaster survivors in Iwate, Miyagi, and Fukushima prefectures. Among the respondents, we extracted responses from 308 people who used shelters and transformed the data for these respondents into person-period data. As a result, 826 observations were included in the analysis, and a discrete-time model was used to analyze this data. The results showed that age and single-person households were associated with more extended shelter stays. However, these effects were no longer observed in the Fukushima sample, and the evacuation order due to the nuclear accident affected shelter stays. Finally, the application of the analysis results to the assistance of disaster survivors was discussed.
