Design and Analysis of "How many X's do you know" surveys for the study of polarization in social networks

调查人员收集新数据并开发新的分析方法来测量和研究美国社会网络中两极分化的各个维度。这个项目扩展了“你知道多少个X”调查的理论和实践，作为研究社会联系与社会和政治态度之间关系的一种手段。人们普遍认为，美国社会在社会、经济和政治方面正变得越来越异质。研究人员开发了新的方法，通过应用新的统计方法来研究美国的互动模式，来测试这种说法在多大程度上是正确的。这些数据是通过综合社会调查收集的，并根据熟人、友谊和信任关系的模式评估美国社会网络的规模和社会融合水平。研究人员利用这些数据来分析拥有跨越种族、宗教、收入和政治意识形态的社交网络的社会和人口预测因素。通过这样做，这项工作还将提供新的数据和数据收集工具，并提出分析这些数据的新方法，从而加强网络分析方面的研究。

The investigators collect new data and develop new analysis methods to measure and study various dimensions of polarization in social networks in the United States. This project extends the theory and practice of ``How many X's do you know'' surveys as a means of studying relations between social connections and social and political attitudes.There is a widespread perception that American society is becoming more heterogeneous along social, economic, and political dimensions. The investigators develop new methodology to test the extent to which this is true by applying new statistical methods to study patterns of interaction in the United States. The data are collected through the General Social Survey and assess the size of social networks and the level of social integration in the United States based on patterns of acquaintance, friendship and trusting relationships. The investigators use these data to analyze the social and demographic predictors of having a social network that bridges across race, religion, income, and political ideology. By doing so, this work will also enhance research in network analysis by making new data and data collection instruments available and by proposing new methods for analyzing these data.
