SEAMS - Standardized ethnically attributed mass surveys, version 1.1
收藏资源简介：
SEAMS integrates a large number of global and regional mass surveys, such as the World Values Surveys and the Afrobarometer. It serves two purposes: - First, it provides standardized information for major public opinion concepts, for instance on (dis-)satisfaction with government institutions, vote intentions, perceptions of belonging to a discriminated group, and ethnic self-identification. - Second, it provides systematic information on survey respondents’ ethnicity, region of residence, language, religion, and phenotype, which is linked to existing datasets, including EPR and CPSD. Thereby, it enables researchers to study how time-varying country- or group-level variables (such as democratization, GDP growth, and ethnic power-sharing) affect public opinion and vice versa. The current version integrates information from 98 unique survey waves, which together cover 2’071’315 respondents nested in 1372 country years and 148 countries. Future releases will add more variables (e.g., on left-right orientation and willingness to protest), surveys, and information on the heterogeneous question items underlying SEAMS’ standardized variables. What is new in this version (1.1): - added standardized variables on vote intentions, ethnic party vote, and ethnic self-identification - updated codebook with description of underlying survey items of these new variables
SEAMS整合了大量全球及区域大规模抽样调查数据，例如世界价值观调查（World Values Surveys）与非洲晴雨表调查（Afrobarometer）。该数据集具备两大核心用途：其一，为各类核心公众舆论概念提供标准化信息，例如对政府机构的满意度与不满情绪、投票意向、对自身属于受歧视群体的认知，以及族群自我认同；其二，提供关于调查受访者的族群归属、居住地区、语言、宗教信仰与表型特征的系统性数据，且此类信息可与EPR、CPSD等现有数据集建立关联。借此，研究人员得以探究随时间动态变化的国家层面或群体层面变量（如民主化进程、GDP增长率、族群权力分享机制）如何影响公众舆论，反之亦可研究公众舆论对上述变量的反作用。当前版本整合了98个独立调查波次的数据，共计覆盖2071315名受访者，这些受访者嵌套于1372个国家-年份样本单元中，涵盖148个国家。未来的数据集版本将新增更多变量（例如左右政治取向与抗议意愿相关指标）、调查数据源，以及SEAMS标准化变量所依托的异质性调查题项信息。 本版本（1.1）的更新内容如下： - 新增了关于投票意向、族群政党投票以及族群自我认同的标准化变量 - 更新了代码手册，对上述新变量所依托的底层调查题项进行了详细说明
