社会調査の回収率は,標本から母集団の傾向や地域差を適切に推定するための重要な指標である.本研究では,回収率の地域差とその規定要因を明らかにすることを目的として,全国規模の訪問面接・留置調査を実施しているJGSS(日本版総合的社会調査)の回収状況個票データを分析した.接触成功および協力獲得という二段階のプロセスを区分した分析の結果,接触成功率・協力獲得率には都市化度や地区類型によって大きな地域差がみられた.この地域差は,個人属性や住宅の種類などの交絡因子,さらに調査地点内におけるサンプルの相関を考慮した多変量解析(マルチレベル分析)によっても確認された.したがって,回収状況は個人だけでなく地域特性によっても規定されていることが示された.しかし,接触成功率・協力獲得率には説明されない調査地点間のばらつきが残されており,その理由の一つとして,ローカルな調査環境とでも呼びうる地域固有の文脈的要因の存在も示唆された.

The response rate is an important indicator of the reliability and validity of a sampling survey. Recently in Japan, especially since 2005, major social surveys have experienced a substantial decline in response rates, and researchers have become concerned about the worsened survey environment. In this paper, we sought to examine the regional differences in survey response rates and their individual and geographic determinants.<br>The data we used were individual data on survey responses to the national representative sample survey with face-to-face interviews in Japan (JGSS: Japanese General Social Surveys) in 2005 and 2006. We distinguished the two-stage process of survey response: (a) whether the investigator was able to meet with those surveyed; and (b) whether they participated in the survey. The differences were then analyzed based on individual and regional characteristics. Large regional differences, measured by the degree of urbanization and neighborhood typology, were observed in both processes. This means that the regional difference in the response rate was also large, because the rate can be obtained by multiplying (a) by (b). We also performed multivariate analysis adjusted for individual attributes such as age, gender, and house type and considering the clustering nature of the samples within the same surveyed area (i.e., multilevel analysis). The results showed that the regional differences in the survey response remained statistically significant, although they were partially explained by the respondents' individual attributes.<br>The current study elucidated that the survey response rate to a face-to-face interview is determined by geographic factors as well as individual attributes of the respondents. Additionally, we confirmed regional variations in the survey response rate between surveyed areas which cannot be explained by the degree of urbanization and neighborhood type, indicating the existence of “local survey environments” that have geographically unique and contextual factors that affect the response rate.
